Best Gmail Alternative for Privacy

Gmail is free because Google monetises your data. Marco connects to your @gmail.com address over IMAP, so you keep your address and your mail, but Google loses the interface that tracks your behavior. No ads, no content scanning, no data monetisation. Free forever.

Free Superhuman Alternative

Superhuman is fast and polished, but $30/month and limited to Gmail and Outlook. Marco offers broad IMAP provider support, full offline capability, and the same triage-first philosophy for free. The keyboard gap is real; the price gap is bigger.

Concerned About Spark Mail Privacy?

Spark routes your email through Readdle's servers for collaboration and AI features. If you use Spark as a solo user, you may be paying a privacy cost for team features you don't need. Marco processes everything locally — no server-side content analysis.

Looking for a Hey Alternative?

Hey requires a new @hey.com address and a $99/year commitment. Marco is free forever, works with your existing email addresses, and supports any IMAP provider. If you want better email without changing your address, Marco is the shorter path.
