The Sender Blacklist lets you stop email from specific addresses, entire domains, or wildcard patterns — before it ever reaches your inbox.
It works across all your aliases at once. A blocked sender can't get through any of your aliases, not just the one they were using. You can add rules manually, and some rules are added automatically when suspicious senders are detected.
There's also a distinction between your personal rules and global rules — the latter are managed by AliasFleet and apply to all accounts.
