Slashy gives you three levels of control over unwanted email: block a sender inline, unsubscribe from a mailing list inline, or bulk unsubscribe from dozens of senders at once in Settings.
Settings Unsubscribe page showing sender list with Block and Unsubscribe buttons

​
Inline Block: Cmd+U

While viewing a thread, press Cmd+U to block the sender. Future emails from that address are handled automatically. A confirmation toast appears with Undo (z or Cmd+Z).
Blocking is per-email-address. If a sender uses multiple addresses, block each separately.

​
Inline Unsubscribe: Cmd+Shift+U

Press Cmd+Shift+U to unsubscribe from the mailing list. Slashy detects the unsubscribe mechanism and executes it automatically:
MethodHow It Works
HTTP POSTOne-click RFC 8058 standard (fastest, most reliable)
HTTP GETOpens the unsubscribe URL for older platforms
MailtoSends an unsubscribe email as fallback
If no unsubscribe headers exist, Slashy falls back to blocking the sender.

​
Bulk Unsubscribe

For comprehensive cleanup, go to Settings > Unsubscribe:
1

Browse senders

See all senders ranked by volume with message counts and unsubscribe method
2

Block or unsubscribe

Click the button on each sender you want to stop
3

Background processing

Slashy handles each sender individually using the best method
This is the same tool from onboarding. If you skipped it during setup, return any time via Settings.

​
Default Actions for Blocked Senders

Configure what happens to future emails from blocked senders in Settings > Unsubscribe:
ActionResult
FilterHidden from inbox views, still accessible in All Mail
ArchiveImmediately archived (moved to Done)
TrashMoved to Trash, permanently deleted after 30 days

​
Managing Blocked Senders

Your complete blocked list lives in Settings > Unsubscribe. Each entry shows the sender, unsubscribe method used, and date blocked. Click Unblock to restore normal delivery.
Unblocking does not re-subscribe you to a mailing list. You need to re-subscribe at the sender’s website.

​
Bulk Actions from Inbox

Select threads with Shift+J/Shift+K or Cmd+A, then Cmd+U to block or Cmd+Shift+U to unsubscribe from all selected senders. A progress indicator shows processing status.
