Blocked Senders

Blocked senders are the opposite of the allowlist. Any email from a blocked domain or address goes straight to trash, without AI classification, without hesitation. You've decided you're done with these senders.

You can block by domain (e.g. dominos.com) to catch every sender on that domain, or by specific address (e.g. noreply@dominos.com) to target a single sender. Both are managed from Contacts › Manual.

This is useful for persistent senders that don't honor unsubscribe requests, or that keep reappearing from slightly different addresses within the same domain. Block the domain once and that's the end of it, as far as your inbox is concerned.

Specificity and conflict resolution

You can block by domain or by specific address. A domain entry catches every sender from that domain, including subdomains. An address entry catches only that exact address.

Priority order when entries conflict:

  • Blocked address wins over everything, including an allowlisted domain. If mattsenter.com is on your allowlist but newsletter@mattsenter.com is blocked by address, that address gets trashed regardless.
  • Allowlisted domain beats a blocked domain. The allowlist is checked before domain-level blocks. If a domain appears on both lists, the allowlist wins.
  • Domain blocks apply last. If a sender isn't explicitly allowed and isn't address-blocked, a matching domain block trashes the message.

Like the allowlist, blocking runs before AI classification. Blocked messages are trashed immediately.
