In-Depth Email Rendering Previews, but Navigation Limits Slow Reviews

The rendering page from the creative tools is what I use. This tool offers many tabs that allow for an in-depth review of the email. The preview tab allows for a quick overview of the rendering on many different devices, allowing us to adapt the codes to fix problems before they occur

Clear Deliverability Insights, Proactive Support

I really appreciate how prepared Anna is for our monthly calls. She brings a packed agenda, and it feels worth our time to hear her recommendations, insights, and best practices. She’s proactive about identifying things for us, always available for questions in our shared Slack channel, and I feel taken care of. I’m impressed by how smart she is in this space and by the guidance she gives us. Inbox Monster helps us get a high-level view of what affects our deliverability and email reputation, identify issues, and address them proactively. It makes email deliverability make sense. The dashboard is pretty user friendly, and I appreciate the inbox alerts. They show us when there’s a problem and make it easy to see the affected ISP, campaign, and inboxing rate, with a link to view the campaign in the dashboard. The email alerts are really valuable and convenient because we don’t have to go into the platform every day; we can take an alert to Slack, tag Anna, and ask her to look into it.
