TLDR: choose Postmark for a simple weekly check, Kevlarr for client-scale monitoring
Pick Free DMARC Weekly Digests by Postmark if
Best for a low-risk domain that only needs a weekly DMARC pulse
The first domain took about 10 minutes to add because setup was only a DMARC TXT record and email verification.
Microsoft 365 and Google Workspace appeared clearly in the weekly email when authentication passed cleanly.
The parked domain showed the spoof sample, but the email format left sender ownership and next steps to us.
Free plan available
Pick Kevlarr if
Best for operators handling several domains, clients, or recurring DMARC work
The three test domains stayed grouped in the dashboard, which made the parked domain and marketing subdomain easier to compare.
Kevlarr separated Mailchimp, SendGrid, and the support desk sender more cleanly than a weekly email report.
Forwarded mail with SPF failure was easier to explain because the interface separated forwarding noise from real spoofing.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric covering enforcement readiness, source resolution, setup, support, MSP workflow, alerting, hosted records, blocklist (blacklist) monitoring, pricing clarity, and time to enforcement. Higher is better in every row.
Postmark wins on no-cost simplicity. Kevlarr wins on operating depth.
Free DMARC Weekly Digests scored high on pricing transparency and fast setup because the first domain only needed a DMARC TXT record and the weekly email arrived without extra configuration. It lost points where our test required investigation depth: the unknown sender needed manual research, the forwarded SPF failure needed explanation, and there was no hosted SPF, MTA-STS, blocklist (blacklist), or multi-client workflow. Kevlarr scored higher on source resolution, MSP workflows, and support because the dashboard grouped clients and filtered forwarding noise, but paid pricing and hosted-record coverage were less clear.

Signal vs workflow
Postmark gives a narrow weekly signal. Kevlarr gives a broader working console.
Postmark's free product is useful when the job is to confirm whether one domain has obvious DMARC traffic problems. Kevlarr is the better fit when the buyer needs to classify sources, separate forwarding noise, and prepare client-ready reports. The buying criterion is whether the tool only names a sender or also gives guided fixes and automated issue detection; Suped's product is built around that workflow.
Free DMARC Weekly Digests by Postmark
Microsoft 365 surfaced fast
SendGrid detail was capped
Forwarded SPF needed explanation
Kevlarr
Google Workspace grouped cleanly
Mailchimp separated by domain
Spoof sample raised quickly
Free DMARC Weekly Digests by Postmark was quick to configure and clear enough for the first week of monitoring. Microsoft 365 and Google Workspace were easy to recognize when SPF or DKIM passed with the visible From domain. SendGrid and Mailchimp appeared in the weekly source list, but the top-source cap made the support desk sender and the unknown sender harder to separate once the marketing subdomain became active. The SPF pass with visible From mismatch and the forwarded mail SPF failure both needed our explanation because the weekly email did not turn either case into a policy-safe recommendation.
Kevlarr gave us more room to investigate the same traffic. Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender were easier to review by domain, and the parked domain made the spoof sample stand out faster. The DKIM pass on a subdomain stayed visible without losing the parent-domain context, and the SPF pass with visible From mismatch was easier to isolate from clean sender traffic. The unknown sender still needed human classification, but the workflow made it easier to capture a next step instead of treating it as one more unexplained IP.
User experience
Fast start vs daily control
Postmark is easier on day one. Kevlarr is easier after the first incident.
Postmark's setup is hard to beat for a simple domain because the experience ends in a weekly email. Kevlarr takes longer to learn, but the extra screens matter once a team needs to explain an unknown sender or defend why a forwarded SPF failure is not a spoofing event.
Free DMARC Weekly Digests by Postmark
Fast DNS copy step
Email-only review loop
Unknown sender stayed unresolved
Kevlarr
Three domains stayed grouped
Forwarding filter reduced noise
Unknown sender had workflow
Onboarding Free DMARC Weekly Digests by Postmark took the least effort on the primary corporate domain. The generated DMARC record was easy to copy, and the first weekly email made Microsoft 365 and Google Workspace traffic readable. The experience became slower when we added the marketing subdomain and parked domain because each finding had to be read inside an email cycle. The unknown sender stayed unresolved until we traced the IP outside the tool, and the forwarded mail SPF failure needed manual explanation for a non-technical stakeholder.
Kevlarr took more clicks during setup, but the three-domain view paid off by the second week. The marketing subdomain did not blur into the corporate domain, and the parked domain gave us a clean place to watch the unauthorized spoof sample. Finding the unknown sender still required investigation, but the interface gave us a better place to keep context. Explaining forwarded mail was also easier because forwarding noise was visually separate from the spoof sample.
Support
Self serve vs assisted operations
Postmark support fits a free monitor. Kevlarr support fits a managed DMARC motion.
Postmark's free workflow sets clear expectations: copy the DNS record, verify the domain, and read the weekly email. Kevlarr is better suited to buyers that need setup help, DNS handoff notes, escalation paths, and onboarding conversations for larger or partner-led deployments.
Free DMARC Weekly Digests by Postmark
Self-serve DNS setup
Support depends on account
No enterprise handoff path
Kevlarr
Specialist setup help available
DNS handoff was clearer
Partner onboarding had structure
For Free DMARC Weekly Digests by Postmark, support expectations were modest and consistent with the free product. The DNS handoff was a generated DMARC TXT record and the support path was mainly self-service unless the account was already a Postmark customer. That worked for the primary domain, but it left us writing our own explanation for the marketing subdomain's DKIM pass and the forwarded SPF failure. We would not treat the free product as an enterprise onboarding path.
Kevlarr felt more prepared for assisted setup. During our test plan, the product flow matched the kind of handoff an MSP or IT partner needs: domain setup, DNS checks, source review, report sharing, and escalation for ambiguous senders. The support expectation was also clearer for managed DMARC work than for pure self-serve use. The tradeoff is that deeper service levels and commercial terms still need direct confirmation.
Suitability
Single domain vs client operations
Postmark fits a simple owner. Kevlarr fits teams with repeated DMARC work.
Postmark is the practical choice when one person wants a weekly free check on a domain with limited sending complexity. Kevlarr is stronger for MSPs, IT partners, and teams that need customer grouping, recurring reports, and handoff notes. If client operations matter, test MSP workflows and alert quality early; Suped's product treats those as buying criteria alongside source identification.
Free DMARC Weekly Digests by Postmark
Best for one domain
Weak client separation
Email reports only
Kevlarr
Built for MSP grouping
Client reports worked well
Pricing needs sales clarity
Free DMARC Weekly Digests by Postmark fit the simplest SMB scenario in our test: one corporate domain, a small set of approved senders, and a person willing to read a weekly email. It was much less comfortable for the marketing subdomain and parked domain because account separation, domain grouping, recurring stakeholder reports, and client handoff were not part of the free workflow. For an enterprise or MSP, the operational burden moves back onto the team.
Kevlarr fit the MSP and operator profile more naturally. Customer and domain grouping made it easier to separate the corporate domain, marketing subdomain, and parked domain without mixing ownership. Recurring reports were more useful for client handoff, and the dashboard made it easier to explain why the support desk sender needed attention. SMBs can still use it, but the product made the most sense once the buyer had several domains or customers to manage.
What each tool feels like after 90 days of real use
Free DMARC Weekly Digests by Postmark
A simple weekly check for a single accountable owner
After 90 days, Free DMARC Weekly Digests by Postmark felt like a useful smoke alarm. It told us that the corporate domain had normal Microsoft 365 and Google Workspace traffic, that the marketing subdomain had active SendGrid and Mailchimp volume, and that the parked domain had a spoof attempt worth attention.
The limits became clear as soon as the work moved beyond awareness. We still had to classify the unknown sender, explain the forwarded mail SPF failure, document why the DKIM pass on a subdomain was acceptable, and write our own owner notes for the support desk sender.

Kevlarr
A working console for teams managing more than one domain
After 90 days, Kevlarr felt more operational. We kept the primary domain, marketing subdomain, and parked domain separate, reviewed Microsoft 365 and Google Workspace as expected senders, and spotted when Mailchimp or SendGrid traffic needed a domain-specific explanation.
The product was strongest when the test case needed triage. Forwarded SPF failures were less distracting, the spoof sample on the parked domain was easier to isolate, and client-style reports made handoff easier. The weak point was commercial clarity: public data did not map every paid DMARC capability to a public price.
Where it wins
Cleaner multi-domain workflow
Useful forwarding noise reduction
Client-ready reporting
API-friendly operating model

Postmark's $0 price is a public list detail for Free DMARC Weekly Digests by Postmark checked on May 15, 2026. Kevlarr's paid DMARC prices are not publicly listed; indexed generic prices were not used because DMARC limits were not verifiable. Domain and volume fit is estimated against the four scenarios.
If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Source ownership after detection
Postmark surfaced the unknown sender and support desk traffic, but the email report did not turn those findings into owner-ready remediation steps. Suped connects source identification to guided fixes so the next action is clear.
Alert routing beyond weekly review
Postmark's weekly cadence was too slow for the spoof sample, while Kevlarr reduced forwarding noise but still required careful routing decisions. Suped focuses alert quality around the difference between routine forwarding, misconfiguration, and abuse.
Clearer scaling for teams
Postmark's free workflow did not handle account separation, and Kevlarr's deeper MSP and managed DMARC pricing needed confirmation. Suped has published starter pricing and MSP workflows that make multi-domain planning easier to budget.
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.
