I've tried so many Linux email clients - why Aerion just replaced Geary as my top pick

Jack Wallen/ZDNET Follow ZDNET: Add us as a preferred source on Google. Linux has several email clients, but this new one is tops for me. This app supports several email accounts, is free to use, and is open source.

For the longest time, Geary has been my default email client . It's lightweight, simple, and offers a nice, modern GUI. But I've always been bothered by certain issues with this client. For example, if I use Geary with a tiling window manager, the GUI doesn't always behave properly depending on where I place it. If the Geary window isn't wide enough, when I click an email, the email consumes the entire app (instead of leaving the email list and sidebar visible). Also, when I launch Geary on Pop!_OS, the app sometimes doesn't appear until I run the geary command. Although these aren't exactly deal-breakers, they're annoying. Also: Here's my favorite email trick for cleaning up inbox clutter - automatically So, when I heard about a new, cross-platform email client available for Linux (as well as MacOS and Windows), I had to try it out. The client in question is called Aerion , an open-source app that is Linux-first, privacy-focused, lightweight, and efficient. The GUI is well laid out, so anyone can jump in and start using the app right away, with no learning curve. Aerion is sponsored by 3DF, a Hong Kong-based IT consultancy that calls itself "Asia's leading technical operations partner." For those concerned about the trustworthiness of 3DF and Aerion, you can view the source code for the email app in the official GitHub repository . Aerion isn't chock full of features, so you don't have to worry about getting overwhelmed; it's basic, easy, and clean.
