Switching from Mimestream to Kanmail

Mimestream is a polished, Mac-native Gmail client. People tend to leave it for three reasons: it’s subscription-only (no one-time purchase), it’s Mac-only, and it’s Gmail-only. If any of those is a dealbreaker, here’s how to move to Kanmail.

What changes when you switch

MimestreamKanmail
PricingSubscription only (~$4.99/mo or ~$49.99/yr), no lifetime licenceOne-time purchase, no subscription
PlatformsmacOS onlymacOS, Windows, Linux
ProvidersGmail / Google Workspace onlyGmail, Outlook, iCloud, Fastmail, any IMAP
LayoutNative Gmail-style listKanban board — columns you drag email through

The trade-off to be honest about: Mimestream is deeply tuned to Gmail’s native feel via Google’s API. Kanmail uses well-implemented IMAP with smart label handling and Gmail-style search (why that matters). A different approach, and the board layout is a genuine change in how you work. Try the free version before you buy.

Your email is safe → there’s nothing to export

This is the reassuring part: your mail lives on Gmail’s servers, not inside Mimestream. Switching clients doesn’t move or risk any email. You’re just pointing a new window at the same mailbox. No export, no import, no backup needed.

Steps

  1. Download Kanmail from kanmail.io and install it (free to try, no time limit).
  2. Add your Gmail account with Sign in with Google using same OAuth flow you’re used to. (Gmail setup →)
  3. Your Gmail labels and mail appear in Kanmail automatically.
  4. Build your board: choose which labels become columns. (Boards & Columns →)
  5. Add your other accounts too — the Outlook or iCloud address Mimestream couldn’t handle can now sit on the same board.
  6. When you’re happy, cancel your Mimestream subscription. (Do this last, once Kanmail is set up the way you want.)
