Everest presents itself as a robust, all-in-one email success platform. We found its DMARC reporting features to be integrated seamlessly into a broader deliverability ecosystem. This means you are not just getting DMARC insights, but also a suite of tools that address pre-send, in-flight, and post-send email performance.
Beyond DMARC data, Everest provides extensive reputation monitoring across IPs and domains, inbox placement testing, and email validation. Key features we appreciate include: a customizable dashboard that aggregates various data sources such as Google Postmaster Tools and Microsoft SNDS, and the ability to track engagement analytics to understand subscriber behavior.
InboxMonster's feature set is keenly focused on deliverability and reputation management, offering valuable insights into how emails land across different service providers. We particularly noted its weighted inbox placement analysis, which can be critical for businesses with diverse subscriber lists.
The platform excels in offering real-time insights into blocklist (or blacklist) and spam trap monitoring. While its DMARC reporting is effective, the emphasis often lies in the accompanying consulting services, ensuring that the data translates into actionable strategies for improving email channel performance. Their Creative Suite also adds pre-send design and accessibility tools.
How easy is each product to use

User experience

First comparison imageSecond comparison image
Our hands-on experience with Everest revealed a clear interface and generally easy navigation. The customizable dashboards are a standout feature, allowing us to tailor the view to our specific daily needs without being overwhelmed by extraneous data. Setting up these dashboards and integrating with various ESPs, such as Salesforce Marketing Cloud, felt straightforward.
However, some users have noted a learning curve, especially with the sheer volume of information available. While the platform aims for a 360-degree view, we found that navigating to very specific data points could sometimes require a few extra clicks or prior knowledge of where everything resides, a minor critique in an otherwise well-designed tool.
InboxMonster offers a user-friendly and intuitive platform. We found it easy to grasp, even for those less versed in the intricate details of email deliverability. Its reports are designed to be actionable, which means less time deciphering complex charts and more time implementing solutions. The ability to share campaign reports directly via a link also streamlines team collaboration.
Despite its overall ease of use, some reviews indicate that the platform's numerous features and tabs can be a bit overwhelming when attempting in-depth analysis independently, outside of scheduled consultations. We believe that while the initial learning curve is minimal, maximizing all features might require leaning on their strong support system.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
Everest's support structure, particularly its Customer Success Managers, often receives positive remarks. We experienced responsive and diligent assistance, especially during the setup phase and when dealing with platform-side issues. They are clearly invested in helping users leverage the platform effectively, offering advice and guidance.
That said, some feedback suggests that after initial onboarding, the level of proactive engagement can vary, and getting highly technical questions resolved might take longer. While there are office hours for support, a dedicated, consistently proactive account manager for day-to-day issues isn't always a given, which could be a drawback for teams needing constant, deep dives into technical challenges.
InboxMonster truly shines in its customer support and consulting services. Our experience, and consistently echoed in feedback, highlights their hands-on approach and proactive engagement. Their team often identifies and flags potential deliverability issues before we even notice them, providing actionable insights and remediation plans.
The support extends beyond platform usage, with consultants often acting as subject matter experts, guiding strategy, and even coordinating directly with email service providers on behalf of clients. This deep, personalized partnership makes InboxMonster an excellent choice for organizations seeking not just a tool, but also expert guidance to navigate complex deliverability landscapes.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Everest is well-suited for a broad range of users, from SMBs to large enterprises, especially those seeking a comprehensive, integrated platform for all their email deliverability and analytics needs. Its tiered pricing model with granular volume-based options makes it accessible for smaller senders, while the Professional and Enterprise editions cater to larger teams requiring advanced features and higher volumes.
For MSPs, Everest's multi-domain monitoring capabilities with 'child accounts' could be beneficial, though its primary focus is not explicitly on multi-client management. Enterprises will appreciate the detailed reporting, API access, and the ability to integrate various data sources into a single dashboard for a holistic view of email program health.
InboxMonster is an excellent fit for mid-market to enterprise-level organizations that value hands-on support and expert guidance alongside a robust deliverability monitoring platform. SMBs might find the starting price point higher, but those with critical email programs could justify the investment for the personalized service.
For MSPs and enterprises, the exceptional customer service, proactive issue resolution, and consultative approach are significant advantages. We believe InboxMonster is particularly strong for those who might not have in-house deliverability experts and need a partner to actively help navigate complex email ecosystems and improve sender reputation effectively. It offers a true partnership, which can be invaluable.

Drawbacks and what to watch out for

Everest faces scrutiny for its sales practices and perceived difficulties in platform transitions, with some users noting a lack of detailed metrics for major ISPs. InboxMonster, while highly praised for support, has a higher entry cost and some users find its extensive data overwhelming without guidance, leading to potential underutilization of features.
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
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 What problems is Everest solving and how is that benefiting you? Helped delivery to MS-based email

Josie + InboxMonster has helped our email team tremendously!
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.

Good for Beginners in Deliverability...Could be Better for Pros
What do you like best about Everest? Setting up Dashboards to monitor all deliverability metrics What do you dislike about Everest? Support is okay, but it could be lot better Navigational aids are not comparable to other industry-rated tools. Recommendations to others considering Everest: New to the deliverability landscape, this tool is perfect for you, but if you are an industry pro and understand the ins and outs of deliverability I would look elsewhere. What problems is Everest solving and how is that benefiting you? Improving inbox placement Lowering spam complaints

What problems is Inbox Monster solving and how is that benefiting you? Inbox Monster is helping us manage and get insight into deliverability problems when they arise. There is a great toolset that is built behind this management and the additional tools with respect to content rendering is super helpful.

Review after using more than 2 months
What do you like best about Everest? 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.

Valuable Deliverability Insights
What do you like best about Inbox Monster? Inbox Monster provides a lot of valuable insights into how are email deliverability is across many different email service providers. What do you dislike about Inbox Monster? Inbox Monster has many features and data sets, but not all of the data feels immediately actionable and I don't understand what every feature does. What problems is Inbox Monster solving and how is that benefiting you? Before Inbox Monster, we couldn't see where our emails were landing or what seeds were having deliverability issues.

It's been really difficult to switch over to Everest from Return Path due to seedlist testing issues
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.

A Game-Changer for Email Deliverability
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.

So far not so good
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!

Great tool with excellent consulting support
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
