Somebody recommended the FairEmail email client for Android to me.
So far it works really well. Setup is easier than K9 was for me.
Security and transparency seems to be OK too.
Can you please tell me if it supports swipe to next message? It’s the one feature that keeps me using the default Android email because it is so easy and fast to go through all of my messages.
If you mean what I think you mean, then yes it does.
