The platform is easy to use, very intuitive, and we've had EXCELLENT support from our account rep David. He helped us through our transition from a shared IP to a dedicated IP, in conjunction with a major company rebrand, and the addition of new sending subdomains. With his guidance and expertise, it went more smoothly than I could have possibly imagined. The reports are insightful and clear. We're beyond pleased with the service we've received, and I'd consider Inbox Monster a must-have addition for providing peace of mind when it comes to something as critical as deliverability. Review collected by and hosted on G2.com. What do you dislike about Inbox Monster? Have not found anything to dislike. It's been a great product for us. Review collected by and hosted on G2.com. What problems is Inbox Monster solving and how is that benefiting you? We ran into deliverability issues while on a shared IP and made the business decision to transfer to a dedicated IP, along with separate sending subdomains. Inbox Monster helped us a) come to the conclusion that this was the best option for us based on our volume and sender reputation and b) helped us immensely throughout the transition. We made this critical move with minor issues, and any we ran into (ie. Microsoft), our rep David handled quickly and expertly to minimize any interruptions. Review collected by and hosted on G2.com.

We have the opportunity to work with InboxMonster, and I can confidently say their service has been nothing short of outstanding. From the outset, their team, specially Anna Kotlikov, demonstrated a level of professionalism, expertise, and commitment that exceeded our expectations. What truly sets InboxMonster apart is their deep understanding of the email ecosystem. They provide clear insights, actionable data, and strategic recommendations that help us improve inbox placement, monitor our sender reputation, and optimize our deliverability practices. Every interaction with their team was thoughtful and results-driven. Their platform is powerful yet intuitive, giving us the transparency we need to make informed decisions quickly. The support team is highly responsive, knowledgeable, and genuinely invested in our success — it felt more like a partnership than a vendor relationship. InboxMonster's dedication to excellence, attention to detail, and proactive communication made a measurable impact on our email program. I would wholeheartedly recommend their services to any organization looking to take email deliverability to the next level. Review collected by and hosted on G2.com. What do you dislike about Inbox Monster? One potential area for improvement would be the addition of benchmarking tools or industry comparison data within the platform. While InboxMonster offers robust visibility into our own deliverability and performance, having the ability to measure results against industry standards or peer groups would add helpful context, especially when reporting to stakeholders. This isn’t a limitation by any means, but rather an opportunity to add even more strategic value for users. Review collected by and hosted on G2.com. What problems is Inbox Monster solving and how is that benefiting you? InboxMonster is solving key challenges around inbox placement visibility, sender reputation management, and proactive alerting. By giving us real-time insight into where our emails are landing across major inbox providers, we can address deliverability issues before they impact performance. The platform also helps us monitor domain and IP reputation across blocklists and spam traps, allowing us to protect our sender health. Additionally, customizable alerts ensure we’re immediately notified of any sudden changes, so we can take action quickly. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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.

I've been in the deliverability space for over a decade and have used all of the major players, including ReturnPath (now Validity) & SparkPost (now MessageBird) - and we've always found ourselves back at Inbox Monster. The application is intuitive, the reports generated are useful and actionable...but what makes Inbox Monster top is the team of experts working behind the scenes. Their knowledge of the best practices, ESP policies, and reputation recovery is above most in the industry. Review collected by and hosted on G2.com. What do you dislike 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. Review collected by and hosted on G2.com. 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.
