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!
Our team has used Gmelius for close to two years and the features really enhance the productivity of our team. Collaborating with home-office staff is easy and efficient. The batch emails and sequences features are incredibly useful - and we love that it's all part of a very affordable package!
