"Empowers Proactive Deliverability Monitoring"
4.5/5
What do you like best about Inbox Monster?

I find Inbox Monster very useful for continuously monitoring the tracking and deliverability for our sending domain. It helps take proactive measures and troubleshoot any issues to understand the root cause and suggest fixes. The initial setup was fairly easy, with the account manager handling most of the configuration, which made things smooth. It's been really effective in flagging spam traps and deliverability concerns proactively, helping to maintain our domain's reputation. Review collected by and hosted on G2.com.

"Proactive Support and a Comprehensive Deliverability Testing Suite"
4.5/5
What do you like best about Inbox Monster?

-Proactive customer support: Dedicated deliverability expert who flags issues and intervenes before they affect campaigns.

-Ease of use: Intuitive and straightforward UI makes everyday monitoring easy.

What do you dislike about Inbox Monster?

Nothing immediately jumps out. ...I wish we always had a concrete reason for a given "blip" in deliverability. That's just not reality though. But Inbox Monster does a good job identifying/explaining potential root causes and suggesting mitigation steps. Review collected by and hosted on G2.com.

"Detailed IP & Domain Insights with Fast Spam Trap and Authentication Visibility"

"Exceptional Deliverability Insights and Support"
5/5
What do you like best about Inbox Monster?

We use several dedicated IPs to send millions of promotional and transactional emails to our members each month. Maintaining a strong sender reputation and tracking inbox placement rates is extremely important for our business.

For the past several years, we've used Inbox Monster to monitor these metrics.

The Inbox Monster platform is intuitive and easy-to-use, and their customer support has been exceptional. On multiple occasions, we've been able to use Inbox Monster's reporting to identify and resolve deliverability issues before they have widespread impacts on our business. Review collected by and hosted on G2.com.

What do you dislike about Inbox Monster?

No downsides to speak of. I'm happy with the platform. Review collected by and hosted on G2.com.

"A deliverability must-have."
5/5
What do you like best about Inbox Monster?

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.

"Review of InboxMonster"
5/5
What do you like best about Inbox Monster?

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.

Response from Laura Sullivan of Inbox Monster

Thank you so much for the feedback. We love that it feels like a partnership to you, too. We'll be sure to follow up about benchmarking tools. Thanks for your partnership!

"Josie + InboxMonster has helped our email team tremendously!"
4/5
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. 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.
