I'm a huge fan of Gmelius. Ever since I discovered it, it has made my emailing sane. The Snooze feature that then resurfaces emails automatically that didn't get a response means I can send it and forget it. I've used the mail merge feature to survey clients and it was amazing.
I switched to Gmelius from a competitor earlier this year and I could not be happier with that. I rediscovered some CRM features that I have missed before. Highly recommend.
Really happy about Gmelius. It really supercharges Gmail for open tracking, follow ups and delayed sending. I really use all of their features. I am eagerly waiting for their app on iOS. One big missing feature is a form of contact management, I use another app for this for now. Only downside is that when you open your browser after a while, all the open notifications are sent one-by-one, they cannot be aggregated, so it can become a little annoying. Other than that I fully recommend this product. Context, I am a single person company and do in-house and remote contracting work. Other, full fledged CRM's just did not fit my bill, especially the sales parts of them. I don't need them and many tools focus on that. Gmelius is the perfect fit for my needs.
I have tried many gmail productivity tools out there and non of them can beat Gmelius!
This is a great product for anyone using Gmail. It offers a simple yet thorough interface for tracking email reads. It also adds several productivity features to Gmail and Inbox by Gmail, such as snooze, send later, signature import, and a kanban board. Runs smoothly. Accessible interface.
