Discover the #1 alternative to Boomerang!

Gmelius is becoming a common upgrade for Boomerang users. Especially for small and medium-sized teams searching for the next-level. When it comes to email management and team collaboration, our feature set is a perfect fit.

At Gmelius we understand our success depends on the success of our users. It’s what wakes us up every morning; providing teams with the tools they need to achieve their goals.

Ex-Boomerang users credit a few of our key features for their satisfaction. Our shared labels for example, easily manage all of your project and client-specific communications. While Gmelius’ kanban boards give each team member a clear visual of the projects at hand.

With access to the rest of our features – all integrated into your Gmail inbox – your team will be well-equipped to succeed.

Our sales reps were using another sales tool that was cumbersome and didn’t work consistently… When I found Gmelius and saw a live demo, I knew we’d found a match with the needs of our team. It’s been very well received, and the product support is outstanding.
