Interestingly, I went the other way. I used to have mutt for years, then went through a dark phase (macOS Mail.app, Evernote and Things) and finally concluded to Emacs with mu4e. Integrating mail with Emacs was the best idea ever, because Emails include either todos or serve as reference in projects.

Do you use GMail? If so, how much pain is was to configure your setup to connect to it reliably? And handle multiple e-mail accounts? I ask, because in the past I toyed with switching to using Emacs as my e-mail client, but aways got stuck on configuring the whole setup to work reliably and seamlessly.
I'm using Mu4e with 4 different mail accounts, though and it's completely seamless and easy to compose.
