Glockapps offers a comprehensive suite of email deliverability tools, extending beyond DMARC reporting to include spam testing, IP reputation monitoring, and uptime monitors. Their DMARC reporting provides detailed insights into authentication results, helping users identify and troubleshoot issues related to SPF, DKIM, and DMARC alignment.
We found the content analysis and spam score features particularly useful for pre-send checks. While strong in core DMARC functionalities like source and forward detection, it integrates these within a broader deliverability toolkit designed for a more self-service approach to email health.
InboxMonster specializes in high-touch email deliverability consultancy, with its platform offering robust tools primarily for monitoring inbox placement, spam trap detection, and reputation analysis. Their DMARC reporting, while present, is often part of a larger, hands-on service package aimed at actively improving overall email performance.
The platform excels at providing weighted inbox placement insights and real-time alerts. Instead of just raw data, InboxMonster focuses on actionable intelligence, often delivered through their professional services team, which is a key differentiator in how their features are leveraged.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
Glockapps presents a functional interface with a lot of data. For users who understand email deliverability concepts, navigating through the various reports and tools is relatively straightforward. The dashboard allows for quick access to spam tests, DMARC reports, and other monitoring features.
However, for newcomers, the sheer volume of information can sometimes feel overwhelming. While powerful, some aspects of the interface could benefit from further simplification to make it more accessible for those without a deep background in email infrastructure.
InboxMonster offers a clean and intuitive user interface, particularly for its core deliverability monitoring features. While the platform itself provides comprehensive data, a significant part of the user experience comes from their dedicated support team, who often interpret complex data for clients.
Users consistently praise the platform's ease of use and the clarity of its reporting, especially when paired with the insights from their consultants. The learning curve for leveraging all features independently can be steep, but their white-glove service mitigates this by guiding users through the most critical aspects.
Which product has the best support

Support

LogoLogo
First comparison imageSecond comparison image
Glockapps provides support primarily through online channels, offering chat and email assistance. We've found their responses to be generally helpful for technical queries related to their platform's functionalities. Documentation and FAQs are also available for self-service troubleshooting.
However, direct phone support is less common, with calls sometimes directed to an answering machine. For users needing highly personalized, hands-on guidance for complex deliverability issues, the support model can feel less proactive compared to highly consultative alternatives.
InboxMonster is renowned for its exceptional, high-touch customer support, often described as a true partnership. Their model typically includes a dedicated deliverability consultant who actively works with clients, providing actionable insights and managing issues directly with internet service providers (ISPs).
Users consistently highlight the proactive nature of their support team, with consultants often identifying and flagging issues before clients are even aware. This consultative approach is a core part of their offering, making them a strong choice for those who value expert guidance over self-service.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Glockapps is well-suited for a broad range of users, from small businesses (SMBs) to larger enterprises, and even managed service providers (MSPs) who prefer a more self-directed approach to email deliverability. Its free tier offers a starting point for individual users, while paid plans scale with message volume.
It's particularly effective for marketing teams and email administrators who want a robust toolkit for ongoing monitoring and troubleshooting, provided they have some internal expertise. While it provides comprehensive data, it's less ideal for organizations seeking extensive hands-on consultancy for deliverability challenges.
InboxMonster is an excellent fit for mid-market to enterprise-level organizations, including MSPs managing complex email programs for multiple clients. Its high-cost, high-value model is designed for businesses that require a dedicated expert partner to navigate intricate deliverability landscapes.
It's particularly beneficial for companies where email is a critical revenue channel and where the cost of deliverability issues is high. While SMBs might find the pricing steep, larger organizations will appreciate the comprehensive service, strategic guidance, and proactive problem-solving offered by the InboxMonster team.

Drawbacks and what to watch out for

Glockapps, while offering a wide array of tools, sometimes struggles with customer support responsiveness and user onboarding for less technical users. Some historical reviews also point to billing confusion and policy changes. InboxMonster's primary drawback is its higher price point, which may be prohibitive for smaller organizations, and a slight learning curve for fully leveraging the platform independently without continuous consultant input.
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.

Ridiculous payment confirmation policy
What do you like best about GlockApps? I used to use this app all the time, unfortunately their policies have made it unusable What do you dislike about GlockApps? Was asked to provide bank statements and a photo ID to buy an upgraded plan. Totally over the line in terms of privacy and unnecessary for a piece of software. What problems is GlockApps solving and how is that benefiting you? Not email deliverability

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.

Great toolset and helpful account support
What do you like best about Inbox Monster? The toolset is very robust and they are consistently adding to the functionality. The account support has also been great and incredibly proactive.

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.

Good Software, immoral practice
What do you like best about GlockApps? Good software with great email delivery analysis. To be able to test on a freemium and see if it land into the inbox of Gmail, Outlook and other accounts is great. The analysis feature detects most of the issues. What do you dislike about GlockApps? Their email delivery consulting service is a scam, they advertise a money-back guarantee, and during the consultation, they only try to upsell you instead of giving the right solution. They don't provide the invoice for the purchase, and even when asked multiple times, they ghost you as soon as you request the money-back garantee. Also, their email delivery analytics does not detect link issues with Microsoft accounts. What problems is GlockApps solving and how is that benefiting you? It help detect email delivery issue, used it to detect why email did not landed into microsoft account. I wasn't able to find the real reason with Glockapps but it helps to know if the email were delivered or not into Microsoft email accounts (hotmail, outlook,...)

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.

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.

Good App for Spam tests
What do you like best about GlockApps? Detailed report from various email servers and basic suggestions to overcome the trouble. What do you dislike about GlockApps? It will be helpful if we can figure out the reason or where the missing emails are. What problems is GlockApps solving and how is that benefiting you? To check the domain reputation of users and suggest ways to improve

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
