We found Everest to be a robust, all-encompassing deliverability platform. Its DMARC reporting is part of a much larger suite of tools, including inbox placement testing, email validation, and reputation monitoring across various ISPs. This means we get a holistic view of our email program, not just DMARC.
The platform excels in providing detailed DMARC data analysis, allowing for deep dives into authentication failures and potential spoofing attempts. However, its broad feature set might feel overwhelming if DMARC is our sole concern.
Postmastery, on the other hand, presents a more focused approach, especially with its DMARC Reports module. It provides clear, actionable insights specifically for DMARC implementation and monitoring. We appreciated its clarity in presenting DMARC aggregate and forensic reports.
While Postmastery also offers broader deliverability consulting, the DMARC reporting tool itself is designed to be straightforward for DMARC specialists. It might lack the extensive supplementary tools found in a full-suite platform like Everest, but it covers DMARC thoroughly.
How easy is each product to use
User experience
Navigating Everest can be an experience in itself, akin to exploring a vast mountain range. The sheer volume of features means there is a learning curve to truly master the platform. While the dashboards are highly customizable and can be tailored to specific needs, we sometimes found ourselves searching for specific reports or configurations, especially when digging beyond basic DMARC data.
Once accustomed, the interface is logical, but we feel it caters more to seasoned email professionals who are comfortable with complex data sets and multiple moving parts. Its power lies in its depth, which requires patience to unlock.
Postmastery offers a more streamlined and perhaps less intimidating user interface. Its DMARC module focuses on presenting essential DMARC data clearly, making it relatively quick to grasp and utilize. We found the reporting dashboards to be intuitive for DMARC analysis, providing a clear overview of compliance and threats.
For users primarily interested in DMARC without the need for a multitude of other deliverability features, Postmastery’s focused design provides an efficient and less cluttered experience. It is built for purpose, offering simplicity where Everest offers breadth.
Which product has the best support
Support
Our experience with Everest's support varied. While some G2 reviews indicate responsive account managers, we also observed comments about initial setup difficulties and a desire for more consistent, in-depth technical assistance for specific issues. The support is generally good for navigating the platform's extensive features.
For complex deliverability challenges that extend beyond DMARC, the comprehensive nature of Everest means that support needs can also be more complex, requiring a good understanding of their ecosystem.
Postmastery's approach often combines its DMARC reporting with consultancy, implying a more hands-on support model. While explicit G2 reviews are absent for direct feedback, the focus on tailored solutions suggests a more personalized support experience. We anticipate that support would be deeply knowledgeable about DMARC specifics.
This model is particularly beneficial for organizations that prefer a consultative partnership alongside their tools, ensuring expert guidance through DMARC implementation and ongoing management.
Who should use each product
Suitability
Everest is particularly well-suited for enterprise-level organizations and large marketing teams that require a comprehensive suite of deliverability tools. For MSPs (managed service providers) managing numerous client accounts, its multi-tenancy capabilities and extensive reporting are valuable. However, the pricing and feature set might be overkill for small to medium businesses (SMBs) whose primary concern is DMARC compliance.
Its strength lies in providing a 360-degree view of email performance, making it ideal for those who need to manage reputation, inbox placement, and engagement alongside DMARC.
Postmastery caters effectively to organizations that prioritize DMARC implementation and monitoring, from SMBs to enterprises looking for a dedicated DMARC solution. MSPs can leverage its focused reporting for clients, especially if DMARC is a key deliverability component they offer. We found it a strong contender for those seeking expertise specifically in DMARC, rather than a broad deliverability platform.
Its pricing model, which is often custom, can be adapted to various scales, making it a flexible option. It is an excellent choice for businesses that prefer a specialist approach to email authentication.

Drawbacks and what to watch out for
Everest, while comprehensive, can be costly and presents a steep learning curve due to its extensive feature set. Some users have reported issues with setup and customer service consistency. Postmastery, while focused and effective for DMARC, lacks explicit public pricing, requiring a contact for quote, and its DMARC module might not satisfy those seeking a broader deliverability suite.
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.

Shady sales practice shoot down ok software - don't use these guys
0.5 / 5
What do you like best about Everest?
The software is decent and the validation program works for Microsoft (Hotmail etc) based email, but not for Gmail
What do you dislike about Everest?
Terrible sales practice. Call you within 45 days of renewal, when you ask to change you are told you can't as there is a hidden lock-in in the T+Cs, you need to give 60 days' notice.
Legal but shady, we renewed and then immediately gave notice for next year. They used to be good not so now.
Recommendations to others considering Everest:
Find another supplier, these guys are sharks

Able to help in domain and IP blacklisted daily checking.
Quick display the domain reputation status.
After using Inbox placement service and domains/IP pools, feel their interface is nice and clear.
What do you dislike about Everest?
Does not provide the IP or domain score with ISP like Hotmail and Yahoo.
Inbox percentage in accurate due to need send to all seed's ISP just able to get the score.
Inbox percentage for Hotmail does not accurate.
Does not provide whitelisting service for IPs. It is just a simple domain blacklisting status system.
What problems is Everest solving and how is that benefiting you?
None of the problem have been solving through this Everest. It just a inbox placement display system only.
Easily noticed on domain blacklisted only. Other than this are nothing.

2.5 / 5
What do you like best about Everest?
I like the accessibility to create dashboards and share across the org.
What do you dislike about Everest?
The only downside was that it was extremely difficult to switch over to everest from return path due to seedlisting issues mainly from our ESP, Braze
What problems is Everest solving and how is that benefiting you?
Mainly using everest for deliverability measurement. havent had the chance to use it for more since we've been spending a lot of time switching platforms.

So far not so good
3.0 / 5
What do you like best about Everest?
We've been working on setting up since mid-August, but due to issues on the platform side, have been unable to fully set up. That said, our account manager has been responsive and diligently working on getting the issues resolved, so I would say that the user support is the best part.
What do you dislike about Everest?
We're on our third month trying to get set up due to platform issues, which I think is not great considering the price. Return Path set up went much smoother, and we were able to get started right away without a hitch.
Recommendations to others considering Everest:
Prepare for a longer-than-estimated setup process.
What problems is Everest solving and how is that benefiting you?
Monitoring email deliverability is of utmost importance to our business. Being able to see when things take a turn for the worse and being able to react quickly helps us keep our email reputation positive and keeps our emails in user's inboxes!
