How to Stop Getting Emails Without Unsubscribing

The unsubscribe link in marketing emails is supposed to be the solution. But sometimes, clicking it is the wrong move.

When you should NOT unsubscribe

• Spam from unknown senders — Clicking unsubscribe confirms your address is active. The sender (or the network behind them) now knows your address is real and monitored. You may receive more spam, not less.
• Phishing emails — The "unsubscribe" link may be a phishing URL. Never click links in emails you do not trust.
• Emails from senders who do not honor unsubscribe — Some senders ignore the request entirely, or re-subscribe you to a different list.

In these cases, you need alternatives.

Method 1: Block the sender

Every email provider has a block function:

• Gmail: Open email → three dots → "Block [sender]"
• Outlook: Right-click → Block
• Apple Mail: Click sender name → "Block Contact"

The limitation: blocking is per-address. If the sender rotates addresses (common with spam operations), you are playing whack-a-mole. For more detail, see How to Block Emails on Gmail, Outlook, iCloud, and Yahoo.

Method 2: Contact states in Cleanbox

If you use Cleanbox, set the contact's state to blocked. This rejects all future email from that sender at the server level — the email never reaches your mailbox. The sender receives a bounce notification.

Alternatively, set the state to muted if you want to keep receiving the emails but never see them in your inbox. Muted emails are delivered but automatically marked as read.

Method 3: Create a filter with deny action

For persistent senders who rotate addresses, create a filter that matches a pattern rather than a specific address:

• Filter by domain: From contains @spammer-company.com → Deny
• Filter by subject pattern: Subject contains "act now" or "limited time" → Deny
• Filter by category: Category is "Gambling" → Deny

This catches future emails from the same operation even if they change the sender address.

Method 4: Disable the alias

If you use a dedicated alias for a service (which you should), and that alias starts attracting unwanted email — just disable it. One click, no more email to that address. Your real address was never exposed.

This is the strongest argument for using email aliases: you do not need to negotiate with spammers. You just shut down the alias and move on.

Method 5: Lower the spam threshold

If unwanted email is getting through your spam filter, lower the spam threshold on the affected alias. A threshold of 3-4 catches most spam automatically. Combine with whitelisting for trusted senders so they are never affected.
