There are three ways to stop unwanted email in Slashy. They look similar, but they do very different things. Pick the right one for the situation.

​
Comparison

​
Block a sender

Use this when there is nothing to politely unsubscribe from. Block moves the current message and every future message from that address to spam without notifying the sender.
1

Open the thread

From the inbox, hit Enter to open the message.
2

Block

Press Cmd+U. Past and future mail from this address goes to spam.
3

Undo if needed

Press z or Cmd+Z on the confirmation toast to reverse the block.
Blocking is per-address. If a sender uses multiple addresses, block each one.

​
Mark as spam

For a faster, lighter-weight version of blocking, right-click any thread in the list and choose Mark as spam (or press !). The message moves to spam immediately without opening it. You can also ask the agent to do this in bulk, for example “Mark everything from this sender as spam.”

​
Unsubscribe from a mailing list

Use this for newsletters and product updates you actually signed up for. Slashy reads the list’s unsubscribe headers and sends the right request on your behalf.
1

Open the newsletter

Open the most recent message from the list.
2

Unsubscribe

Press Cmd+Shift+U. Slashy detects the list’s unsubscribe method and runs it.
3

Confirm

A toast shows the request was sent. Reputable senders will stop within a few days.
If the message has no unsubscribe header at all, Slashy offers to block the sender instead, since there is no list to leave. Alongside the base unsubscribe request, Slashy offers two one-step add-ons: archive existing clears every past message from that sender in the same action, and block the domain stops future mail from any address at that sender’s domain, not just the one you unsubscribed from. Domain blocking isn’t offered for large shared providers like Gmail or Outlook, since that would catch mail from unrelated senders too.

​
Bulk unsubscribe

When you want to clean house, run bulk unsubscribe from Settings → Inbox → Unsubscribe. Slashy ranks senders by volume and shows the detected unsubscribe method for each one.
1

Open the page

Go to Settings → Inbox → Unsubscribe.
2

Pick the senders

Scroll the list and check the senders you want gone.
3

Run

Click Unsubscribe. Slashy processes each sender in the background.

You can skip the settings page entirely and ask the agent instead: “Clean up my newsletters.” The agent identifies newsletter senders and unsubscribes from them the same way bulk unsubscribe does.

​
Choosing the right action

  • If you are angry at the message and want it gone right now: mark as spam.
  • If you want the sender permanently blocked: block.
  • If you actually subscribed at some point: unsubscribe.
  • If your inbox is full of years of newsletters: bulk unsubscribe, or ask the agent.
A block is appropriate even for technically legitimate senders, for example a vendor that keeps re-adding you to lists after you leave them. The sender does not know you blocked them, and the mail stops landing in your inbox.

​
Managing blocked senders

Your full blocked list lives in Settings → Inbox → Blocked senders. Each row shows the address, the date blocked, and an Unblock button. Unblocking restores normal delivery, it does not re-subscribe you to any list.
