Klar fits better when Spam is the problem: a filter that learns on your Mac, without giving a service access to your mailbox
The honest picks
- Leave Me Alone
- Built for bulk unsubscribing: it follows unsubscribe links for you and rolls newsletters into digests. Its spam blocker learns in its cloud and targets cold outreach. Pick it to prune subscriptions, not as a spam filter.
- 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.
