Comments about Apple Mail as an Alternative to Thunderbird

Guest
I have used Thunderbird with IMAP for years, but the tiny font problem on Mac is now a dealbreaker, and with my decades of emails and folders, Thunderbird is flailing when fetching ail or moving folders. Apple Mail does what I need it to: manage multiple Gmail accounts, not be too slow, and let me adjust font size. The arrangement of folders/mailboxes in Apple Mail is not as intuitive as Tbird but I can deal with that.

As a Firefox user, I have tried to love Thunderbird but it just can't compete with Outlook, IMHO.

It works. Much less buggy. Better integration with Windows. Encryption/Signing.Works over remote desktop without losing pieces of itself. Search is crappier though.

It doesn't let you read existing email, it's a chat client that uses an IMAP mail server as its back end

Delta chat (as the name also indicates) is for chatting, and it uses email as a backend. This means user will chat as if they are on WhatsApp or etc. but in background DeltaChat communicates via sending and receiving emails.

It's an IM over Email client meant to replace messenger type apps.
