Premail is in alpha testing. Use at your own risk.

Subscriptions

The Subscriptions tab scans your inbox for mailing list subscriptions. It looks for List-Unsubscribe headers and list-specific signals, with List-Id as the definitive mailing-list proof. Shared-recipient mail without List-Id is treated as a group, not a mailing list.

For each subscription found, you can:

  • Unsubscribe: Premail uses the unsubscribe link embedded in the message to remove you from the list. This happens asynchronously. Some lists honor it within minutes; others treat the legally permitted 10-business-day window as a maximum rather than an upper limit.
  • Keep: adds the sender to your Unsubscribe Protection list so Premail never tries to remove you from it automatically.

Unsubscribe Protection

The protection list is for subscriptions you actually want. Anything on this list will be left alone even if it looks like a mailing list. Useful for transactional emails that happen to use mailing list headers, or newsletters you genuinely enjoy.

Unsubscribing through Premail is not guaranteed. It depends on the sender's compliance. For persistent senders that don't honor requests, Blocked Senders is the more reliable option.
