# How do I permanently block a sender in Gmail? — Adinand Email Cleaner

**Blocking sends that sender's future mail to Spam — it does not delete what they have already sent, and it does not take you off their list.** Google's block page puts the effect in one sentence: "After you block a sender, all future emails from them go to Spam" (*Block an email address in Gmail*, read 23 September 2026 — https://support.google.com/mail/answer/8151). Its spam page adds that the block sticks: "When you block a sender, even when you remove their emails from Spam, Gmail still automatically identifies their emails as spam" (*Report spam in Gmail*, read 23 September 2026 — https://support.google.com/mail/answer/1366858).

## What blocking does and does not do

- **Does:** route future messages from that address to Spam until you unblock it — Google's page puts the unblock list under Settings, in **Filters and Blocked Addresses**.
- **Does not:** touch the mail already in your account, or the storage it occupies. Google's page talks only about future emails. Clearing the backlog is a separate job — [clearing one sender's history](https://adinandemail.com/answers/delete-all-emails-from-one-sender).
- **Does not:** unsubscribe you. For a list you joined, Google's advice is different: "If you signed up to receive messages from a specific sender and no longer want them, click Unsubscribe or Go to website."

## The limit to know: blocking is per address

Google's page is written around blocking an email address, and it does not say a block extends to any other address. A company can mail you from several — `news@`, `offers@`, a `noreply@` — and each one is a different address. If mail keeps arriving after a block, look at which address it came from.

Unsubscribing is not a whole-company switch either. Google's unsubscribe page warns: "When you unsubscribe from a specific email, it might only unsubscribe you from a single mailing list from the sender," and points to **Manage subscriptions** to find the rest (*Unsubscribe from an email*, read 23 September 2026 — https://support.google.com/mail/answer/15433283). A filter built from a search that matches every address the sender uses is the other way to cover them all.

## Block, filter, or unsubscribe — choosing quickly

- **Unsubscribe** when you once signed up and the sender is real.
- **Block** when a specific address should never reach your inbox again.
- **Filter to Trash** when the mail is harmless but endless — "delete" is one of the actions Google lists for a filter (*Create rules to filter your emails*, read 23 September 2026 — https://support.google.com/mail/answer/6579).
- **Report as spam** for mail you never asked for. Google says that "As you report more spam, Gmail identifies similar emails as spam more efficiently" — which is why, for a sender you did sign up to, its own tip points to Unsubscribe instead.

## Where we fit

The filter option is the one that is slow to set up by hand, and it is the one that scales. [Adinand Email Cleaner](https://adinandemail.com/) groups your Gmail by sender, so you can see who actually keeps arriving, clear their backlog in a few taps, and set an auto-trash rule so future mail from them never reaches the inbox again — three rules on the free tier, unlimited on Pro. It reads only email headers, on your device, and it shows the measured space each cleanup gives back.
