Built by a former Apple engineer specifically for Gmail on Mac, it's fast, native, and rock-solid. Nothing else delivers a Gmail experience this polished on macOS.
The gold standard free email client with decades of reliability. Supports any email provider, runs on all major platforms, and has a massive plugin ecosystem for customization.

Our take
If you're a Mac user with Gmail, stop looking — Mimestream is the answer. It feels like Apple built Gmail's official Mac app, and that's exactly what you want.
If you want one email client that does everything without costing a dime, Thunderbird is it. The open-source community has kept it sharp, and nothing else at this price point comes close.
