Kevlarr focuses primarily on DMARC reporting, providing detailed insights into email authentication, mail flow, and potential spoofing attempts. We found its dashboard effective for quickly understanding where emails originate and whether they are DMARC compliant. It excels in filtering out 'noise' such as forwarded emails, which can often clutter DMARC reports.
Beyond core DMARC, Kevlarr offers an API for automation, which is a significant plus for organizations looking to integrate DMARC data into their existing security workflows. It also provides tools to help configure SPF and DKIM, ensuring a comprehensive approach to email authentication. The ability to generate both technical and non-technical reports is a useful feature for communicating with different stakeholders.
InboxMonster provides a broader suite of email deliverability features, with DMARC monitoring being one component among many. Its 'Deliverability suite' offers tools for inbox placement, spamtrap and blocklist (or blacklist) monitoring, and reputation analysis. We noticed a strong emphasis on real-time insights and proactive identification of deliverability issues.
In addition to DMARC, InboxMonster's platform includes creative proofing, device renderings, and accessibility analysis, which are valuable for email marketers. While it offers an API, its primary strength in this area seems to be its comprehensive range of deliverability tools rather than deep DMARC-specific automation. We found its approach more geared towards optimizing overall email channel performance.
How easy is each product to use
User experience
Kevlarr generally offers a clean and intuitive interface, making it straightforward for users to get a clear overview of their email flow and DMARC status. Setting up domains is relatively easy, often with custom DMARC policy generation assistance.
However, we found that navigating some parts of the user interface can sometimes require a bit of searching to find specific pages or detailed statistics. While functional, it might benefit from further refinement to enhance discovery for less frequent users.
InboxMonster presents a powerful yet intuitive platform, lauded for its user-friendly design and ease of onboarding. Its dashboard effectively consolidates crucial information for deliverability and inbox placement, even for those without a strong technical background.
Despite its overall ease of use, the sheer volume of features and data sets can be overwhelming initially. Some users might find it challenging to conduct in-depth analysis independently without guidance, needing time to familiarize themselves with all available metrics and tabs.
Which product has the best support
Support
Kevlarr’s support is frequently highlighted as outstanding and personal. Reviewers consistently praise the responsiveness and helpfulness of their team, especially during setup and when addressing specific DMARC configuration issues.
The support team provides direct assistance, often going the extra mile to guide users through implementation and problem-solving. We found this hands-on approach valuable, particularly for companies new to DMARC enforcement.
InboxMonster offers what they call 'white glove set up' and real-time platform support, which we found to be a significant strength. Their account representatives and deliverability consultants are consistently praised for being knowledgeable, proactive, and instrumental in providing actionable insights.
Users often describe the support as a true partnership, with consultants actively monitoring accounts and offering strategic recommendations to improve deliverability. This level of dedicated, expert guidance is a key differentiator, especially for organizations tackling complex deliverability challenges or dealing with mailbox providers.
Who should use each product
Suitability
Kevlarr is particularly well-suited for Managed Service Providers (MSPs) and small to mid-sized businesses (SMBs) who need a clear, affordable, and focused DMARC monitoring solution. Its multi-domain overview and straightforward implementation align well with the needs of MSPs managing multiple client domains.
For enterprise clients, Kevlarr offers robust DMARC insights and API capabilities for integration, making it a strong choice for those with existing security systems that need to ingest DMARC data. It's ideal for organizations prioritizing email authentication and spoofing prevention as a core security concern.
InboxMonster is an excellent fit for mid-market to enterprise-level organizations, particularly those with sophisticated email marketing programs where deliverability directly impacts revenue. It's highly suitable for teams that require a comprehensive suite of tools for inbox placement, reputation, and creative testing.
While also beneficial for SMBs with significant email reliance, its higher price point and extensive feature set might be overkill for very basic DMARC needs. MSPs could leverage its comprehensive tools, but the pricing structure seems more aligned with larger, direct clients managing high email volumes and complex deliverability programs.

Drawbacks and what to watch out for
When considering Kevlarr, we've noted that while its interface is clean, some users find it challenging to navigate to specific detailed analytics without a learning curve. There's also feedback about limitations in classifying domains and difficulty in discerning 'active' domains, which can impact billing. For InboxMonster, a common observation is the initial complexity due to its extensive feature set, potentially overwhelming new users. Its pricing for advanced features or add-ons can also accumulate, making it a more significant investment.
We have pulled the average ratings from G2 for each product, and also included the most recent negative reviews for each product in full. Positive reviews tend to have less detail and have a higher chance of being fraudulent, so negative reviews are a better signal for your decision.

Josie + InboxMonster has helped our email team tremendously!
4.0 / 5
What do you like best about Inbox Monster?
I'm newer to the email team that utilizes InboxMonster but from what I've gathered from my coworker who has worked with Josie and InboxMonster for over a year, Josie was instrumental in providing actionable insights to enhance deliverability.
What do you dislike about Inbox Monster?
We don't have a proper CRM tool to leverage so InboxMonster isn't as much a problem as the tool we're using for email.
What problems is Inbox Monster solving and how is that benefiting you?
At the beginning of the year, the team discussed solutions such as better domain/IP allocation, stricter demark policies, and monitoring iCloud; they also noted the impact of email frequency and rogue franchisees on complaint rates. Next steps included investigating unsubscribe inconsistencies, exploring click activity data, discussing IP address optimization, and a future demo of Inbox Monster's "Creative Projects" tool; Josie Garcia will also provide further ISP and deliverability information. Most recently, Josie shared SendGrid-specific recommendations, best practices, and provided platform training, including user management, notifications, campaign tagging, subscriber insights, and spam trap analysis.

A Game-Changer for Email Deliverability
4.5 / 5
What do you like best about Inbox Monster?
Inbox Monster has been a life saver for our email program. We have worked with Josie for just under a year, but the amount of dedication and support she provided to analyze our deliverability, help us come up with an action plan to remediate our poor deliverability and sender reputation, and ongoing monitoring of trends after working through our issues, has played a significant role in the health and success of our email marketing.
Josie is always quick to respond and will walk through the issues with us, giving us valuable insights and recommendations along the way. My team does not have a strong background in deliverability, but Josie and the Inbox Monster team, has made a very technical part of email marketing very easy to understand and action against, allowing us to grow our skillset while also educating the rest of the company on deliverability best practices to ensure we do not fall into the same mess that we worked so hard to pull ourselves out of.
In October 2024, we found out, with the help of Inbox Monster, that our inbox rate with Gmail was at 1% with low sender reputation. After working with Josie, we were able to increase and maintain our Gmail inbox rate to 95-100% with high sender reputation within 4 months. I cannot recommend Inbox Monster enough.
What do you dislike about Inbox Monster?
Email deliverability is overwhelming. This is not an Inbox Monster issue. The team at Inbox Monster is incredibly knowledgeable and gives so much information. A lot of the time, the analysis is easy to follow while meeting with the Inbox Monster team, but the amount of numbers and tabs within the platform make it a little difficult to follow on our own. We have a wonderful support team who are willing to meet at our cadence to discuss, but it's a bit difficult to do our own analysis outside of those meetings.
What problems is Inbox Monster solving and how is that benefiting you?
Inbox Monster helps provide valuable insight to our email deliverability and sender reputation.

Kevlarr gives us the possibility to automate DMARC Reports
5.0 / 5
What do you like best about Kevlarr DMARC Monitoring?
Thanks to using Kevlarr we are able to utilize their API and pretty much automate the entire process.
It was sold to us saying that everything done in the webconsole can be done through the API and it was not a lie.
Because of the API we were able to onboard/start Kevlarr completely automated, this made the implementation a breeze.
Ever since we switched to Kevlarr we are more on top of problems and we also have some auto-remedation set up, this was not possible with our previous product.
What do you dislike about Kevlarr DMARC Monitoring?
The user interface is not the best in my opinion, it usually takes some time for me to find the right page. but since we extensively use the API this is not really a big problem. (Could also be that I am not using the interface enough to be used to it)
What problems is Kevlarr DMARC Monitoring solving and how is that benefiting you?
Monitoring of DMARC gives you good insight of email deliverability issues for your customers.
It's important to identify these problems as soon as possible, but in reality its way to easy to forget about it.
Thanks to Kevlarr we are on top of this, we automatically get alerts when something needs our attention.

Great tool with excellent consulting support
4.5 / 5
What do you like best about Inbox Monster?
Clear reporting to understand our deliverability/inboxing, as well as domain/IP reputation factors. And the consulting services offered save us a ton of time, as they leverage existing relationships with email providers to troubleshoot/address inboxing issues. Super easy to use and onboard as well.
What do you dislike about Inbox Monster?
Everything is worth it, but the tool costs more than other deliverability platforms, however, that's largely because they are taking on the work of coordinating with email providers
What problems is Inbox Monster solving and how is that benefiting you?
They offer a one-stop shop of crucial information to understand our sending domain/ip health, and most importantly, offer services that help us work with email providers quickly and effectively. This saves our team a ton of time we would otherwise have to spend coordinating with each ESP
