I am moving away from Protonmail as they do not support certain integrations and features I need for business applications. I just bought a year of email service from NameCheap mostly because it was cheap and I already have my domain with them. I want to get away from having 3 different applications on my phone for different email services I have and would like to have a desktop client for my computers.
I am currently running Fedora 35 KDE Plasma on both my desktop and laptop as well as an iPhone. Ideally same/similar application for both devices but at this point I just need to consolidate so I would settle for one application for my computers and another for my iPhone.
Any suggestions?
