A side-by-side comparison based on expert reviews and real community consensus.

Mimestream wins on polish, speed, and native Mac integration — it's genuinely one of the best email clients ever built for macOS. But it's Gmail-only and Mac-only, which makes it useless for half the people reading this. FairEmail is the choice for Android users who want honest, open-source software that respects their privacy and works with any email provider. The privacy community backs FairEmail hard, and for good reason — it doesn't collect your data, period.

Buy at AmazonFull review →Mimestream is Mac-and-Gmail only — full stop. That's not a limitation, it's a design philosophy, and it's why the app feels so tight. But if you switch to Android, add a non-Gmail account, or hand your laptop to a Windows user, Mimestream is a paperweight. FairEmail works on any Android device with any IMAP-compatible email provider, which is basically every email service on earth. One app is a precision tool; the other is a Swiss Army knife.
Mimestream was built by a former Apple engineer and it shows — every animation, every keyboard shortcut, every context menu feels like it belongs on macOS. FairEmail's UI is honest but utilitarian; it prioritizes function over form, and the setup process will make non-technical users sweat. If you care about your email client feeling *good*, Mimestream wins by a mile. If you care about it being trustworthy and transparent, FairEmail is the answer.
FairEmail is open-source, collects no data, and runs no unnecessary background processes. You can read the code yourself if you want to verify that. Mimestream is a closed-source, subscription-based product — that doesn't make it untrustworthy, but you're taking the developer's word for it. For users who've moved to privacy-respecting email providers specifically to escape surveillance capitalism, FairEmail is the only serious option here.
FairEmail is free with an optional one-time payment to unlock advanced features — you pay once and own it. Mimestream requires a subscription after the free trial, meaning you're renting access indefinitely. Over three years, Mimestream will cost you significantly more than FairEmail's one-time unlock. That said, Mimestream's subscription funds active development from a dedicated team, and the quality shows. You get what you pay for — the question is whether you want to keep paying for it.
