The honest picks
- Gmail
- Very good and included. If you live in Gmail's own apps and are fine with Google processing your mail, you may not need anything else. Klar earns its place when your accounts land in Apple Mail.
- Klar
- Pick Klar if you read mail in Apple Mail and want a modern multilingual model that runs entirely on your Mac. No account, no cloud, nothing to hand over.
