I would use FastMail's web interface full time if I could but I have different accounts on different providers and if I want to use them with a single UI, I have to use a regular desktop client. Can you please convert your web interface into a generic mail user agent which works with all imap and smtp servers? This would be a much nicer solution than redirecting or fetching mails into a single account and imho your web interface feels snappier than MailMate on macOS and eMClient on Windows.
