MailHardener excels in its core DMARC reporting capabilities, offering a robust dashboard that meticulously breaks down DMARC, SPF, and DKIM authentication results. We found its email source identification to be quite precise, helping to quickly pinpoint legitimate senders and unauthorized activity.
Beyond basic DMARC, MailHardener provides strong support for advanced email security standards. It includes SPF flattening, which is a lifesaver for domains with many SPF records, and robust tools for BIMI and MTA-STS/TLS-RPT implementation. This focus on hardening the entire email security posture is a clear strength.
SendForensics, while offering DMARC reporting, places a significant emphasis on overall email deliverability. Its DMARC analysis is solid, providing insights into email authentication, but it really shines in its deliverability testing features, which include spam tests and inbox placement checks. This broader scope is great for marketers and those focused on reaching the inbox.
The platform also offers valuable tools for analyzing email content and identifying potential red flags that could trigger spam filters. While it supports DMARC, SPF, and DKIM, its strength lies less in advanced protocol implementation like MTA-STS and more in providing actionable insights to improve email campaigns, which is a different, but equally important, angle.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
MailHardener's interface is clean and functional. We found the DMARC reports easy to navigate, with clear visual breakdowns of authentication results. Setting up domains and policies felt straightforward, particularly for users already familiar with DMARC concepts. The focus is on clarity and providing the necessary data without excessive frills.
While the setup process is logical, some of the more advanced features, such as configuring custom DMARC policies or troubleshooting SPF issues, require a foundational understanding of email authentication. For a DMARC novice, there might be a steeper learning curve, but the tool provides sufficient guidance within its UI.
SendForensics offers an intuitive and visually appealing dashboard, especially for those new to email deliverability. The deliverability tests are simple to run, and the results are presented clearly, highlighting areas for improvement in a user-friendly manner. This makes it accessible even for users who are not deep into the technicalities of email protocols.
However, we did encounter occasional lag times when running tests or rendering email previews, as noted by some users. While generally easy to use, these minor performance hiccups can sometimes disrupt the workflow. The DMARC reporting, while present, is integrated into the broader deliverability suite, which might feel less focused for pure DMARC management.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
MailHardener provides support primarily through a ticketing system and a comprehensive knowledge base. We found the documentation to be quite detailed, offering solutions for common issues and clear explanations of DMARC concepts. For self-starters, this resource is invaluable.
Our interactions with their support team, when necessary, were generally responsive and knowledgeable, particularly for DMARC-specific queries. While not always instant, the quality of technical assistance was reliable. They clearly specialize in email security protocols.
SendForensics also offers support via a ticketing system and a guide section. The guide is helpful for understanding their deliverability tests and how to interpret results. For straightforward questions, the self-help resources are good.
However, we observed that response times for support tickets can vary, sometimes taking a few hours, other times a few days. While helpful, this inconsistency could be a concern if you require rapid assistance for time-sensitive deliverability issues. They are strong in deliverability but sometimes slower on the DMARC side.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
MailHardener is exceptionally well-suited for organizations that prioritize robust email authentication and comprehensive DMARC enforcement. If your primary goal is to prevent phishing and spoofing attacks, and you need detailed insights into your DMARC compliance, MailHardener is a strong contender. It's particularly beneficial for companies with complex email infrastructures.
For MSPs, MailHardener offers specific plans and features tailored for managing multiple clients' DMARC setups. Enterprises requiring stringent email security and SMBs looking for a solid DMARC foundation will find it highly effective. It’s less about marketing deliverability and more about securing your sending domain.
SendForensics is ideal for email marketers, agencies, and businesses where email deliverability is a paramount concern. If your main objective is to ensure your legitimate emails land in the inbox and avoid spam folders, its suite of deliverability tests and content analysis tools will be incredibly valuable.
While it offers DMARC reporting, it’s best for SMBs and enterprises that view DMARC as part of a broader deliverability strategy rather than a standalone security focus. MSPs can use it for client deliverability, but its DMARC features might be less extensive than dedicated DMARC platforms. It's a great tool for optimizing campaign performance.

Drawbacks and what to watch out for

While both MailHardener and SendForensics offer valuable services, we've identified some areas where each could improve. MailHardener, despite its strong DMARC focus, might present a steeper learning curve for beginners and lacks the granular deliverability testing of its competitor. SendForensics, on the other hand, occasionally suffers from performance lags and sometimes has inconsistent support response times, and its DMARC features are less specialized compared to dedicated security platforms.
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.

Increase your email deliverability with Send Forensics
What do you like best about SendForensics? Easy to use, interface is intuitive to navigate, our whole team can access and use the product with a single sign-on. There is no limit to the number of email tests you can send to Send Forensics to test, so it is not an issue to test every single campaign prior to launch to maximize deliverability. What do you dislike about SendForensics? Lag time has been an issue in the past - emails not rendering in Send Forensics has slowed down my work flow. Support team response has varied from a few hours to a few days to respond to a ticket. Also flags items within email template that are required by CANSPAM law, like our physical mailing address. Also can be glitchy, where previews of emails with flagged content does not render. What problems is SendForensics solving and how is that benefiting you? We run all our emails through Send Forensics prior to launch, to catch spammy words/copy and to improve the likelihood that our emails will reach inboxes of our customers.

SendForensics Review - How it helped us test and get to inboxes
What do you like best about SendForensics? I like that it shows keywords that we can change flagged words to, similar words that you can update and exact content issues. I also like the live inbox placement testing. It also tells you if you should go ahead and send or make some changes and optimize. Send Forensics has different sections that they look at - vocabulary and copywriting, coding and layout, link quality and data collection. Most of our issues fall under the vocab and copywriting/content. The support and the guide section is also really helpful and most of the things we have questions on get answered pretty quickly there. It also is a good price for the service that you get. We looked and did free trials for a lot of companies, and feel Send Forensics gives you a lot of what we needed for a very reasonable price. What do you dislike about SendForensics? You really have to learn to use it and see the correct patterns. Sometimes we will test something and change what they told us to, and when we retest we are hitting less inboxes or getting a lower deliverability than before. Lots of trial and error. Recommendations to others considering SendForensics: Do the free trial, test it out and make sure it works for you first. But if you want to fully see what it can do, pay the low price of $49 a month and do some testing. You will likely get some insights you were not receiving before and it'll help you out moving forward with getting into inboxes. What problems is SendForensics solving and how is that benefiting you? With our current mailing system, we weren't seeing inbox placement and spam score testing. So this is helping a lot by telling us whether the main providers or not would have it fall into the inbox or spam folder. We've come to realize some words that are flagged so we can make the changes before even testing it in Send Forensics, so you do learn a pattern about how these things work. Send Forensics even goes as far as to show you your reputation, deliverability score, blacklists, errors, etc.

Valuable tool that everyone serious with email marketing should use
What do you like best about SendForensics? SendForensics gives you a lot of information regarding your emails, without this tool you would have to use several other tools to be able to view all the information, and it would be much harder to do any real analysis of your “email health”. What do you dislike about SendForensics? I would like more details, especially regarding errors found in “Vocabulary & Copywriting” and “Coding & Layout”. Recommendations to others considering SendForensics: Run the trial and spend an hour investigating, you can quickly see if this is a tool for you. What problems is SendForensics solving and how is that benefiting you? Email marketing is difficult to succeed with, doesn't matter how much money we throw at it. SendForensics enables us to trim and adjust our email campaigns so that we get the maximum possible return on our investment. It's so much faster to find out how to improve our email campaigns with SendForensics.
