Board, not a list

A better Gmail list is
still a list.

Mimestream perfects the single-column Gmail inbox. Kanmail rethinks it: your email becomes columns you drag cards through, so what’s in flight is visible at a glance instead of buried down the scroll.

Not just Gmail, not just Mac

Every account, every OS.

Gmail, Fastmail, iCloud, Yahoo, Yandex or any IMAP host. Unified on one board, on Mac, Windows and Linux. Mimestream is Gmail-on-a-Mac, and only that.

A point we won’t oversell

On privacy, it’s a tie.

Both keep your mail on-device and block tracking pixels by default. Neither routes your inbox through a middleman server. If privacy is your only axis, you can’t go wrong with either.

Where Mimestream wins

If you read one Gmail account, only on a Mac, and never plan to change either — Mimestream is the better app, and we won’t pretend otherwise.

Native Mac craftsmanship

Built in Swift by a former Apple Mail engineer. On a Mac it feels like a first-party app in a way a cross-platform build can’t quite match.

Deep Gmail API integration

Labels stay labels, server-side filters are editable in-app, and Gmail categories and aliases arrive intact — it speaks Gmail natively, not over IMAP.

The single-Gmail sweet spot

One Google account, Mac-only, no plans to change? Mimestream is purpose-built for exactly that and nails it.

More than one account? More than a Mac?

$49. Once.
