The honest picks
- Clean Email
- The pick for digging out an overflowing mailbox: smart folders act on thousands of messages at once, rules keep it tidy, and it reads headers only. Filtering means rules you define yourself, so pick it for cleanup, not detection.
- 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.
