Using a Fully Featured Email App on the Mac

I’ve been looking for an application to use for my email and provide integrated encryption. I was using the Apple mail application which was great except it didn’t do the GPG after the update to macOS Sierra. I was using Postbox for a while, but it’s not reliable. Too many bugs! Then I moved on to using the application called Spark. Spark doesn’t do encryption at all and now I have found Airmail 3 which looks just as good as Spark but does GPG encryption with a plug-in. I also tried Thunderbird which was okay but pretty ugly. So now I have AirMail 3 working I’m quite happy because I don’t have to do the encryption manually. There are lots of settings and customisation possible with Airmail 3. Fingers crossed it will pass the test of time in the stability department.
