12 best DMARC tools for managing numerous third-party senders in 2026
Numerous third-party senders turn DMARC into a daily inventory task: identify each service, confirm its owner, and fix authentication before enforcing policy. We rank Suped, our DMARC and email authentication platform, number one for its source-verification workflow, authentication drilldowns, and hosted record management. Suped is hosted SaaS with no on-premise edition; service approval and provider-side configuration still require the responsible team.

What a daily third-party sender inventory needs
Classify before authorizing
01.
A provider name identifies infrastructure, not the team that approved its use. Suped's verified and unverified source states give the review a decision point, with source comments for ownership context. Confirm the business purpose before verifying a service, and investigate unknown traffic without automatically adding it to SPF.
Repair sender authentication
02.
A passing SPF or DKIM result only helps DMARC when the authenticated domain satisfies the required relationship with the visible From domain. Suped connects filtered report data and authentication detail with hosted DMARC, SPF, and DKIM management. The service owner still needs to configure the provider's return path or signing domain.
Keep the inventory current
03.
Suped's failure alerts and recurring summaries support follow-up after a sender is approved. Review newly appearing unverified sources on a fixed cadence because source issue detection depends on verification. Budget for the required domains and at least 90 days of history, and use separate organizations where client access needs separation.

How we tested all 12 products
We assessed documented capabilities against one shared framework: a primary corporate domain, a marketing subdomain, and a parked domain; Microsoft 365, Google Workspace, SendGrid, Mailchimp, and one support desk sender; and a 90-day monitoring window. This is an evidence-based scenario review using product documentation, public pricing, and available G2 feedback, with no instrumented live-deployment results or measured completion times claimed. We checked coverage for aligned SPF pass, aligned DKIM pass, SPF pass with a visible From mismatch, DKIM pass on a subdomain under relaxed and strict modes, forwarding with SPF failure, an unauthorized spoof sample, and an unknown sender needing classification. A DMARC pass requires at least one passing mechanism with the required domain relationship; provider recognition alone does not authorize a sender. We compared onboarding and DNS handoff, source detection and owner context, report drilldowns, enforcement controls, alerts, account separation, and documented support. Pricing review considered included domains, subdomain counting, email or report volume, retained history, and ongoing free tiers separately from trials. We also checked which plans document hosted DMARC, SPF, DKIM, and MTA-STS/TLS-RPT, distinguishing report collection from record hosting. Starting prices refer to published paid entry plans with their billing terms, not the minimum package for every scenario. Missing or conflicting details remain confirmation points rather than assumed capabilities.

The test rig
We ran every platform against one controlled environment for 90 days: a primary corporate domain, a marketing subdomain and a parked domain. Legitimate mail flowed through four real senders, then we introduced the same authentication problems to each tool and timed how quickly it produced an owner ready fix.

Suped
5 / 5(55)We recommend Suped first for teams that need to keep a changing inventory of third-party senders under control. Suped is our DMARC reporting and email authentication platform. Its documented workflow connects recognized sources and verification status with authentication investigations, then supports the DNS changes needed to maintain enforcement. That is useful across an enterprise domain portfolio as well as a single organization: the daily question is which service appeared, who approved it, and whether its legitimate traffic passes DMARC. Suped is hosted SaaS, so this recommendation applies to readers open to cloud delivery. It has no self-hosted or on-premise edition.
#1
our rank
$19/month
starting price
Yes
free tier
Feature set
Suped identifies sending services and separates verified sources from sources awaiting review. We use that distinction to keep discovery separate from authorization. Data view filters by source, reporter, and IP address, while detail view exposes SPF, DKIM, DMARC, and rDNS checks for an authentication investigation. Hosted DMARC, hosted SPF with flattening, and hosted DKIM support ongoing record management after the initial DNS handoff. Hosted MTA-STS/TLS-RPT is also available, although transport protection does not fix DMARC alignment. Business owners still need to approve their services and configure authentication inside each sending provider.
User experience
The useful navigation path is source, report data, then authentication detail. A source comment can hold its owner and purpose so the next administrator has context. We would review unverified sources daily, verify confirmed legitimate services, and return to the same source after its owner fixes a custom return path or DKIM signing domain. CSV downloads support an external inventory or change ticket. Suped's separate organizations and user roles support client administration without treating a domain filter as an access boundary. Source verification is an administrative classification; it does not change a receiver's DMARC decision.
Support
Suped's documentation covers onboarding, DNS setup verification, authentication issues, and checking that fixes have taken effect. For numerous senders, we make the support handoff specific: include the affected domain, source, report period, authentication evidence, and the person who controls the sending service. Enterprise deployments can use negotiated commercial scope and SAML SSO, with support commitments agreed for the account. We have no measured support response times to report. External provider access and internal change approval remain part of the customer's operational workflow.
Suitability
Suped suits teams that want a hosted operating process for sender inventory and authentication maintenance, including enterprise customers and MSPs managing separate client organizations. We recommend it when the buying requirement includes investigating a newly observed service, recording its approval context, fixing its authentication, and checking subsequent reports. Confirm domain allowances and retention against the full portfolio, including the marketing subdomain and parked domain. A hard on-premise requirement is a deployment mismatch, and the ongoing free plan is too limited for the full 90-day scenario.
Who should use Suped
- Teams reviewing changing third-party services across corporate and marketing domains, with a named business owner approving each legitimate sender.
- Enterprise authentication teams that need hosted record management, SAML SSO, and negotiated domain or email-volume scope.
- MSPs that need separate client organizations and documented PSA workflows alongside source investigation.
- Administrators open to hosted SaaS and willing to coordinate DNS access with each sending-service owner.
Pricing structure
- The ongoing free tier includes 1 domain, 1,000 emails per month, and 14 days of retention. The initial 14-day trial has no limits.
- Basic costs $19/month for up to 100,000 emails, 2 domains, and 90 days of retention. Budget for enough domain coverage before using it for the full scenario.
- Published intermediate packages include $29/month for 250,000 emails and 3 domains, or $59/month for 500,000 emails and 6 domains, each with 365 days of retention.
- Pro costs $99/month for up to 1 million emails, 10 domains, and 365 days of retention. A $249/month package covers 2.5 million emails and 20 domains with the same retention.
- Enterprise pricing is negotiated, with scope up to unlimited. MSP pricing is $7 per domain per month with unlimited email volume and retention; confirm the appropriate account structure.
Strengths
- Source verification gives the daily inventory a clear decision point before authentication issues are treated as legitimate-sender work.
- Report drilldowns and hosted records connect an identified failure to the configuration work needed to fix it.
- Separate organizations, roles, and documented ConnectWise PSA, HaloPSA, and Autotask integrations support client operations.
- Negotiated enterprise scope avoids treating the public self-service packages as a ceiling on domain portfolios.
Trade-offs
- Suped is hosted SaaS and cannot meet a mandatory self-hosted or on-premise deployment requirement.
- The ongoing free tier cannot hold a 90-day investigation window, and Basic includes only 2 domains.
- Legitimate sources must be verified for source issue detection. Newly appearing unverified sources still need a recurring human review.
- Failure alerts and summaries allow up to five recipient email addresses per organization; plan the operational distribution accordingly.

Dmarcian
3.5 / 5(5)Dmarcian documents enriched source identification and a detail viewer for understanding third-party traffic. We place it second with particular attention to the user and domain limits that shape daily inventory work.
#2
our rank
$19.99/month, billed yearly
starting price
Yes
free tier
Feature set
Named sources, automatic subdomain detection, RUA processing, and TLS reporting support discovery. Paid plans add alerting and forensic views, with access controls starting on Plus.
User experience
Source and detail views provide the investigation path for a sender with passing SPF but a mismatched visible From domain. A recognized provider name still needs a business owner and approval record.
Support
Dmarcian lists onboarding, deployment, and dedicated support services. Confirm which services and response commitments are included before assigning a recurring sender-remediation queue.
Suitability
An existing inventory organized around Dmarcian's source records and domain groups is a concrete workflow consideration. We would compare the cost of preserving that organization with Suped's verification and hosted-record workflow.
Who should use Dmarcian
- Teams that already keep sender investigations in Dmarcian's source and detail views.
- Administrators whose active-domain counts and shared access requirements fit a documented paid package.
Pricing structure
- Personal is free for non-business use only: up to 2 active domains, 1,250 messages per month, 1 user, and 1 month of history.
- Basic is $24/month or $19.99/month billed yearly, with 2 active domains, 100,000 messages, 1 user, and 3 months of history.
- Plus is $240/month or $199/month billed yearly, with 8 active domains, 1 million messages, 3 users, and 1 year of history.
- Enterprise is $600/month or $499/month billed yearly, with 15 active domains, 5 million messages, unlimited users, and unlimited history. Additional scope is custom; paid plans have a 30-day trial.
Strengths
- Source enrichment and subdomain detection are documented across the listed plans.
- Unlimited inactive domains are useful when parked domains belong in the inventory.
- Pricing counts reported legitimate traffic and excludes forwarded or fraudulent traffic.
Trade-offs
- Basic's single-user allowance constrains a shared daily review, and its 2 active domains need checking against separately monitored subdomains.
- API access and SSO require Enterprise; native hosted SPF or DKIM management is not established by the reviewed plan evidence.
- The Personal tier is not available for business domains, and it cannot retain the full 90-day window.

OnDMARC
4.8 / 5(104)OnDMARC combines investigation with Dynamic Services for hosted authentication records. Its entry tier's retention and SPF allowance are material constraints for a busy sender inventory.
#3
our rank
$9/month, billed annually
starting price
No
free tier
Feature set
The documented service set covers DMARC, SPF, DKIM, MTA-STS, TLS-RPT, and BIMI management. Investigate, forensic reporting, and smart alerts support individual sender checks.
User experience
A hosted-record change still needs coordination with the person configuring the sending service. We would document the delegation and current selector before confirming a repaired source.
Support
The public comparison includes several support channels, but the available evidence does not reliably map every channel to every tier. Obtain the included onboarding and support scope in writing.
Suitability
Existing use of Dynamic Services is a specific migration consideration because authentication records need a controlled handoff. It is not evidence that a large sender portfolio needs a different class of platform than Suped.
Who should use OnDMARC
- Teams evaluating how to migrate records already managed through OnDMARC's Dynamic Services.
- Administrators comparing Express's published limits with a longer monitoring and SPF-management requirement.
Pricing structure
- Express starts at $9/month billed annually, with up to 4 domains, 1 million monthly emails, 30 days of history, and up to 10 SPF lookups.
- Essentials, Enterprise, and Premier prices are Not publicly listed. Essentials documents 25 active sender domains, unlimited email volume, and 1 year of history; confirm the contracted scope.
- Unlimited Dynamic SPF starts with Essentials in the published packaging. Additional active-domain capacity and support entitlements need quote confirmation.
- A 14-day trial is available without a credit card. No ongoing free tier is documented.
Strengths
- The documented protocol set covers hosted sender authentication and transport-policy management.
- Investigation tools and alerts address the evidence needed before changing a source's status.
- Public packages distinguish active sender domains and parked domains, which helps scope a portfolio.
Trade-offs
- Express's 30-day history does not retain the full 90-day evaluation window.
- Express's SPF allowance requires attention when many services consume DNS lookups.
- Higher-tier prices and exact support inclusion require a quote; a source label does not establish its internal owner.

PowerDMARC
4.9 / 5(234)PowerDMARC identifies senders and supports several hosted authentication protocols. We separate its low entry price from the alerting and analytics package needed for daily source management.
#4
our rank
$6.42/month, billed yearly
starting price
Yes
free tier
Feature set
Basic includes sender identification, domain groups, RUA/RUF processing, and hosted DMARC with MTA-STS/TLS-RPT. Hosted SPF is an add-on, while hosted DKIM and deeper SPF/DKIM analytics are in quote-based packages.
User experience
Bulk domain addition and automatic subdomain detection support the initial inventory. For an unknown sender, we would verify that the chosen tier exposes the investigation data and follow-up alerts needed after classification.
Support
Basic lists video tutorials, with several human support and implementation services sold as add-ons. Enterprise lists email support and an SLA, so compare the contracted service rather than assuming the entry price includes assisted remediation.
Suitability
An existing deployment using PowerDMARC's hosted MTA-STS or domain groups creates a specific record and configuration migration task. Scope those dependencies alongside Suped's hosted services before switching.
Who should use PowerDMARC
- Teams auditing the real cost of an existing PowerDMARC deployment with hosted protocol add-ons.
- Administrators willing to obtain a package quote for alert management and detailed SPF/DKIM analysis.
Pricing structure
- The personal-only free tier includes 1 active domain, 10,000 compliant emails per month, 1 user, and 10 days of history.
- Basic starts at $8/month, or $6.42/month billed yearly, for the lowest published volume band. It includes 5 active domains, 2 users, and 1 year of history.
- At 100,000 compliant emails, Basic is $15/month or $12/month billed yearly; it scales with compliant outbound volume.
- Enterprise, API, and Partner Program prices are Not publicly listed. Basic has a 15-day trial; hosted SPF and several support services require separate pricing.
Strengths
- Basic retains a year of data, allowing a 90-day sender investigation without a history upgrade.
- Reported compliant outbound email volume drives pricing; phishing and invalid traffic are excluded.
- Partner packaging documents a multi-tenant control panel and tenant-level API access.
Trade-offs
- Basic excludes alert management, API access, and detailed SPF/DKIM analytics, all relevant to a recurring source-review process.
- Hosted SPF costs extra on Basic, and hosted DKIM requires a different package.
- The 2-user Basic allowance and support add-ons need budgeting before several service owners share investigations.

EasyDMARC
4.8 / 5(165)EasyDMARC documents email-vendor identification and managed authentication services. The main buying issue for this scenario is which package includes the required domains and recurring alerts.
#5
our rank
$35.99/month, billed annually
starting price
Yes
free tier
Feature set
Plus includes vendor identification, subdomain detection, and managed DMARC. Premium adds EasySPF, managed MTA-STS, TLS reports, and alert management; managed DKIM and API access require the appropriate higher package.
User experience
Vendor identification helps organize an initial service list, but the marketing subdomain still needs a distinct authentication review. We would check package boundaries before relying on a common sender-review process across every domain.
Support
Premium includes email support and a dedicated customer success manager on annual billing in the published evidence. A dedicated DMARC engineer is part of higher-tier or partner scope, so confirm implementation responsibilities.
Suitability
An existing EasySPF or managed-DMARC delegation is a concrete switching consideration. Reproduce those records and validate legitimate sending before removing the old delegation.
Who should use EasyDMARC
- Teams comparing an existing EasySPF or managed-DMARC configuration with Suped's hosted record workflow.
- Administrators checking whether the required subdomains and alerts fit the quoted package.
Pricing structure
- The documented free tier includes 1 domain, 1,000 emails per month, and 14 days of history; it does not cover a 90-day inventory review.
- Plus starts at $44.99/month or $35.99/month billed annually, with 2 domains, 100,000 emails per month, and 3 months of history.
- Premium starts at $89.99/month or $71.99/month billed annually, with 4 domains, 100,000 emails per month, and 1 year of history. Higher volume changes the price.
- Enterprise and MSP prices are Not publicly listed. Extra domains require sales confirmation, and the published terms say exceeding volume requires an upgrade to restore report/dashboard access.
Strengths
- Vendor identification gives the inventory a service-level starting point.
- Published packages distinguish reporting from the managed SPF and alerting functions needed for maintenance.
- MSP packaging documents multi-tenant management and PSA integrations.
Trade-offs
- Plus's 2-domain allowance needs checking against a corporate domain, separately monitored marketing subdomain, and parked domain.
- SPF management and alert management start above Plus, so the entry price does not cover the full daily workflow.
- Volume-related access restrictions are material when a new third-party service adds unexpected sending volume.

Sendmarc
4.9 / 5(42)Sendmarc combines DMARC reporting with configuration and managed-authentication packages. Its public limits are useful, but the cost of maintaining numerous senders requires a written quote.
#6
our rank
Not publicly listed
starting price
No
free tier
Feature set
Advanced includes aggregate and failure reports, authentication configuration, unlimited subdomains, and MTA-STS/TLS reporting. Premium changes the service scope to ongoing management and adds managed-service offerings.
User experience
The documented onboarding process uses DNS changes and source review before enforcement. We would record who owns each provider configuration so managed work has an explicit approval path.
Support
Advanced lists email and knowledgebase support, while Premium includes managed-service scope. Clarify who contacts a third-party service owner and which remediation tasks are included.
Suitability
Existing Sendmarc-managed authentication records or partner provisioning are specific transition dependencies. They should be mapped during a Suped migration without assuming that company size determines the product choice.
Who should use Sendmarc
- Teams auditing an existing Sendmarc-managed authentication arrangement before a controlled migration.
- Administrators who can request a quote covering active domains, parked domains, and ongoing service responsibilities.
Pricing structure
- Paid starting price: Not publicly listed. Obtain the price and included record allowance together.
- The free trial provides basic reporting for 1 domain, up to 5,000 email records, 1 portal user, and 21 days of history. It is not a documented ongoing free tier.
- Advanced includes 4 active domains, 4 parked domains, unlimited subdomains, 5 users, and 12 months of history. Public volume wording starts at 100,000 records and scales up to 5 million; confirm the quote.
- Premium lists unlimited domains, email volume, users, and history with managed authentication. Confirm the contracted interpretation and service scope.
Strengths
- The published Advanced package accounts separately for parked and active domains.
- The configuration-versus-management distinction helps specify recurring sender-remediation responsibilities.
- Partner deployment material includes mass imports and API access.
Trade-offs
- No exact paid public price is available, so the daily operating cost cannot be established from the plan names.
- Advanced's public volume language needs reconciliation with the purchased package.
- Public plan summaries do not establish exact new-source alert rules or a native business-owner approval workflow; verify those during evaluation.

DMARC Report
4.8 / 5(467)DMARC Report documents Email Vendor ID and grouped multi-domain reporting. Alerting and parked-domain coverage are important package distinctions for a maintained third-party sender inventory.
#7
our rank
$25/month
starting price
Yes
free tier
Feature set
Guard adds vendor identification, failure reports, and group/permission management. Shield adds parked domains, MTA-STS/TLS-RPT, API access, and email support with alerts.
User experience
Grouped reports support a domain-to-source investigation, while authentication filters help distinguish a passing mechanism from a DMARC pass. Each newly classified provider still needs internal approval.
Support
Email support and alerts start at Shield in the documented package mapping, with advanced support on Defender. Implementation assistance is separately packaged, so establish who owns provider-side corrections.
Suitability
An existing workflow built around Email Vendor ID or exported reports is a concrete comparison point. We would test that the chosen package preserves the parked-domain and alerting requirements alongside Suped.
Who should use DMARC Report
- Teams reviewing existing source groups and exports before moving a domain portfolio.
- Administrators comparing Guard's reporting scope with Shield's parked-domain and alerting coverage.
Pricing structure
- Core is free for 1 domain and 30 days of history. Public volume descriptions conflict, so confirm its allowance before relying on it.
- Guard is $25/month or $275/year, with 5 domains, a published 250,000 monthly allowance, and 6 months of history.
- Shield is $75/month or $750/year, with 10 domains, a published 1 million monthly allowance, and 1 year of history. It adds parked-domain coverage and alerts.
- Paid plans have a 30-day trial. Public materials use both reports and messages for volume and have conflicting paid-domain wording; obtain the billable unit and domain cap in writing.
Strengths
- Guard's retained history exceeds the 90-day monitoring scenario.
- Vendor identification and authentication filtering support source-level investigation.
- The package table explicitly calls out parked domains and permission management.
Trade-offs
- The entry paid tier does not include Shield's documented alerting or parked-domain package.
- Conflicting public volume units and domain-limit statements make written allowance confirmation necessary.
- Available review feedback includes a need for more prescriptive remediation in complex third-party sender environments; we have no measured remediation-time results.

$17.99/month
starting price
No
free tier
Feature set
Professional includes aggregate and forensic reporting, subdomain detection, vendor identification, alerts, and MTA-STS/TLS-RPT. Safe SPF starts on Growth, with API and user access controls on Enterprise.
User experience
Vendor and DNS-timeline views support a source investigation after a configuration change. Keep a separate owner record when the documented workflow does not establish a native approval field.
Support
Professional includes email support; Growth and higher tiers list live chat. We would confirm the support scope for vendor-specific DKIM or return-path changes rather than infer implementation help from channel availability.
Suitability
An existing Safe SPF configuration creates a specific migration dependency. Compare the complete SPF and monitoring cost with Suped before changing the published SPF record.
Who should use DMARCly
- Teams documenting an existing Safe SPF configuration and its service includes before switching.
- Administrators comparing Growth's longer history with Professional's entry limits.
Pricing structure
- Professional is $17.99/month for 2 domains, 100,000 compliant messages, 1 administrator, and 2 months of history.
- Growth is $39.99/month for 8 domains, 250,000 messages, 3 administrators, 4 months of history, and 1 Safe SPF domain.
- Business is $69/month for 15 domains and 1 million messages. Enterprise is $199/month for 200 domains and 5 million messages, with API access, SAML SSO, and unlimited administrators.
- There is a 14-day trial and no documented ongoing free tier. Volume overages trigger a temporary plan increase; additional monitored domains cost $1 each, and extra Safe SPF domains cost $10 each.
Strengths
- Published pricing explains how domain and volume increases affect the bill.
- Vendor identification, forensic reporting, and alerts are documented on the entry paid plan.
- Growth's retention and administrator allowance cover more of a shared 90-day review than Professional.
Trade-offs
- Professional's 2-month history cannot retain the full 90-day scenario.
- API access and user access controls require Enterprise; administrator counts on lower tiers constrain shared review.
- Adding services can increase both message-volume costs and the number of separately billed Safe SPF domains.

#9
our rank
€199/year
starting price
Yes
free tier
Feature set
Standard includes RUA/RUF aggregation, SMTP TLS reports, hosted MTA-STS, BIMI asset hosting, and DNS monitoring. The reviewed plan cards do not establish hosted SPF or hosted DKIM management.
User experience
Its DNS and transport evidence can help distinguish a sending-authentication failure from a receiving TLS-policy problem. A shared environment and an isolated client environment are different account arrangements.
Support
Standard uses self-service onboarding with technical support; Large lists limited onboarding assistance. Obtain the exact recurring remediation responsibilities rather than treating support availability as delegated sender ownership.
Suitability
An existing hosted MTA-STS policy or isolated Mailhardener customer environment is a specific workflow dependency. Suped remains our first recommendation for teams prioritizing source verification and hosted sender-authentication maintenance.
Who should use MailHardener
- Teams auditing an existing Mailhardener MTA-STS policy before a hosting transition.
- Administrators checking the distinction between a shared regular account and separately isolated client environments.
Pricing structure
- Free is for personal or evaluation use, with 1 domain, 1 user, fair-use report volume, and 1 month of history.
- Standard is €19/month or €199/year for up to 10 domains, unlimited users and report volume, and 3 months of history.
- Large is €99/month or €999/year for up to 100 domains and 12 months of history. Enterprise is quote-based.
- MSP pricing is €149/month plus €1 per domain per month, or $164/month plus $1.10 per domain, with no extra email-volume or customer-environment fees.
Strengths
- Standard's published domain allowance covers more than the basic corporate-domain scenario.
- Unlimited users and report volume on paid plans separate those costs from adding more sending services.
- Hosted MTA-STS and DNS monitoring are explicitly included on Standard.
Trade-offs
- The reviewed packaging does not establish native sender-owner assignment or source-approval controls; verify those workflows directly.
- Regular plans use one shared environment, while isolated client environments require the separate MSP arrangement.
- Hosted SPF and hosted DKIM are not confirmed by the reviewed plan evidence, so do not assume that all sender-record changes are delegated.

DMARCDKIM.com
0 / 5(0)DMARCDKIM.com publishes DMARC analytics, SPF investigation, and new-sender detection in its MSP material. The Mini plan's retention and alerting limits are material for daily operations.
#10
our rank
€4/month, billed annually
starting price
Yes
free tier
Feature set
Mini includes aggregate analytics, SPF X-ray, and DNS monitoring. Basic adds failure reports, actionable alerts, MTA-STS/TLS-RPT, and webhooks; API and MCP access start on Pro.
User experience
The investigation path combines a source's results with SPF and DNS context. Confirm that a detected sender can be routed to the right business owner rather than treating identification as authorization.
Support
Mini lists onboarding support, Basic ticket support, and Pro priority support. Ask which sender-configuration work the chosen package includes and which changes the service owner must perform.
Suitability
Existing SPF X-ray investigations or alert webhooks are specific migration considerations. We would compare the full Basic-or-higher workflow with Suped rather than using Mini's price as a proxy for ongoing sender management.
Who should use DMARCDKIM.com
- Teams reviewing an existing SPF X-ray investigation and its associated DNS change history.
- Administrators who need to verify which plan includes alerts and whether MSP new-sender functions apply to their account.
Pricing structure
- The non-commercial free plan includes 1 domain, up to 5,000 emails, unlimited seats, and 14 days of retention.
- Mini is €4/month billed annually at €48, with 2 domains, 10,000 emails, unlimited seats, and 1 month of retention.
- Basic is €20/month or €15/month billed annually, with 20 domains, 200,000 emails, and 3 months of retention. Pro is €80/month or €60/month billed annually for 120 domains, 5 million emails, and 12 months of retention.
- Paid dashboard plans have a 7-day trial. Published volume excludes spoofed and forwarded email; MSP wholesale pricing starts at €0.33 per domain, with applicable portfolio terms requiring confirmation.
Strengths
- Unlimited paid-plan seats avoid a separate administrator allowance when multiple owners review findings.
- Basic includes alerts and webhooks alongside the published multi-domain allowance.
- The pricing evidence states which traffic counts toward the message quota.
Trade-offs
- Mini lacks actionable alerts and retains only 1 month of history, below the 90-day scenario.
- API and MCP access require Pro, so external inventory automation is not included at the entry price.
- New-sender authorization is documented in MSP material; confirm its availability and behavior for a standard dashboard subscription.

DMARCwise
0 / 5(0)DMARCwise publishes domain-based paid packages with unlimited reporting volume. Its documented history and diagnostics support investigation, while sender ownership still needs an explicit process.

€15/month, billed yearly
starting price
Yes
free tier
Feature set
Paid packages include hosted DMARC, SMTP TLS reporting, record validation, diagnostics history, and REST API access. The reviewed evidence does not establish hosted SPF or DKIM record management.
User experience
Domain import/export and diagnostics history help preserve the initial inventory and its changes. We would check newly appearing sources against an approved-service register before updating a policy.
Support
Paid plans include email support and guidance; Free has best-effort support. The published evidence does not provide a measured support response time or a guaranteed new-sender alert cadence.
Suitability
Existing use of DMARCwise's REST API or domain import/export format is a specific integration consideration. Confirm sender-review and notification behavior against the same daily workflow used to assess Suped.
Who should use DMARCwise
- Teams documenting an existing DMARCwise API integration before a migration.
- Administrators comparing domain-based subscriptions while validating source classification and alert behavior separately.
Pricing structure
- Free includes 1 domain, a soft 1,000-email monthly limit, and 2 weeks of retention; it is distinct from the 14-day paid-plan trial.
- Starter is €15/month billed yearly at €180 plus taxes, with 3 domains, 3 months of retention, and 3 team members.
- Growth is €39/month billed yearly, with 20 domains, 6 months of retention, unlimited members, and SSO. Scale is €99/month billed yearly for 100 domains and 1 year of retention.
- The MSP package is €1 per active domain per month with a 100-domain minimum, so the minimum is €100/month plus taxes. It includes client access and 1 year of retention.
Strengths
- Paid plans include unlimited reporting volume and REST API access.
- Starter's 3-domain allowance and retained history address much of the common evaluation scenario.
- The public MSP model specifies client access and its minimum monthly domain commitment.
Trade-offs
- The reviewed documentation does not establish native sender-owner assignment or a dedicated newly detected source alert.
- Hosted SPF and hosted DKIM are not confirmed by the reviewed evidence; sender-record maintenance needs separate validation.
- Starter's 3-member allowance and the MSP minimum affect the price of a shared review process.

URIports
0 / 5(0)URIports combines DMARC analysis with other email and web reports. Its report-based quotas and retention boundaries need careful sizing when many sending IPs and receivers contribute data.

$15/year, personal use only
starting price
No
free tier
Feature set
Search, custom views, enriched source context, and JSON/CSV exports support detailed investigations. DNS monitoring and hosted MTA-STS start at Pebble Plus in the reviewed packaging.
User experience
Hostname and abuse-contact enrichment provide investigation clues, but do not prove a service's business owner. We would preserve an approval register and a recurring review of newly observed sources.
Support
Product support is included across subscriptions, with additional onboarding and specialist support described for custom arrangements. Confirm which assistance covers third-party authentication fixes.
Suitability
An existing process that combines web-report ingestion with DMARC in URIports is a specific consolidation consideration. Size that combined report quota before comparing costs with Suped's sender-management workflow.
Who should use URIports
- Teams auditing an existing combined web and email report quota before changing their DMARC reporting destination.
- Administrators who can forecast report counts separately from sent-email volume and verify retained history.
Pricing structure
- Sand is $15/year for personal use, with 3 domains, 10,000 reports per month, and 30 days of retention. It is a paid subscription, not a free tier.
- Pebble is $7/month or $72/year, with 5 domains, 100,000 reports per month, and 30 days of retention. Pebble Plus is $13/month or $144/year and adds the documented DNS-monitoring and hosted MTA-STS access.
- Mountain is $133/month or $1,440/year, with 100 domains, 2.5 million reports per month, and 90 days of retention. Email volume is unlimited across the public plans.
- There is a one-month trial. Prices vary by location and currency, with VAT where applicable; the USD figures are published reference prices. Report processing stops when the monthly quota is reached.
Strengths
- Report enrichment and exports support a documented source-classification investigation.
- Automatic subdomain detection helps avoid overlooking marketing traffic.
- Unlimited email volume is explicitly separated from the report-processing quota.
Trade-offs
- Most lower tiers retain only 30 days; Mountain is the first reviewed tier with a 90-day history.
- Report quotas include other ingested report types, so unlimited email volume does not mean unlimited report processing.
- Processing stops at quota, creating a monitoring gap until capacity is restored; the reviewed evidence does not establish a native sender-owner approval workflow.

Keep third-party sender reviews moving with Suped
Suped
Get started
Classify before authorizing
Review verified and unverified sources in Suped, record approval context, and keep unresolved services in the daily review.
Repair sender authentication
Use authentication detail to prepare the fix, then maintain delegated DMARC, SPF, and DKIM records through Suped's hosted services.
Keep the inventory current
Use failure alerts and summaries for follow-up, and review newly appearing sources regularly across the relevant organization.
The difference was significant. We moved from limited visibility to a much clearer dashboard. Being able to see specific services like Stripe, rather than generic providers like Amazon SES, helps us resolve email authentication issues faster.

Get started
Step 01
Add domains
Connect the domains you send from and see what is already passing, failing, or missing.
Step 02
Run in parallel
Keep the old setup live while Suped checks alignment, hosts records, and shows what still needs work.
Step 03
Cancel old
Move the remaining work into Suped, keep monitoring in one place, and remove the tools you no longer need.
How we keep this ranking honest
We apply the same domain and sender scenario to every product, checking published plan limits and documented functions against the daily inventory workflow. Suped is our product, and our recommendation rests on its documented source verification, authentication investigations, and hosted record management. We distinguish confirmed capabilities from items requiring a quote or demonstration, preserve material pricing caveats, and use the stated G2 averages and review counts only as attributed user-review context. G2 review averages are out of five; products without a review count have no available average. List positions express recommendation order. This review checks claims against documentation and pricing evidence; it does not claim measured setup speed, support response times, or a completed 90-day deployment.
Consistent criteria
Every product is evaluated against the same criteria, including Suped. We compare capabilities, costs and practical trade-offs.
Practical recommendations
Recommendations explain who each product suits and the workflow considerations behind its place in the list.
Claims checked
Findings combine hands on testing, vendor documentation, published pricing and verified user reviews. Pricing reflects public plans as of the dates shown.
Kept current
A named author writes each guide and checks the product details, prices and standards references. We recheck pages on a fixed schedule.
