# How to Block a Customer

> Stop a customer from sharing and from receiving new offers, without deleting their data.

Blocking is the strongest non-destructive action on a customer. Use it when you don't want a person in your programme anymore, usually after a confirmed gaming case or a serious complaint, but you don't want to wipe their history.

<Warning>
  Blocked customers stay in your account so you can audit their activity. If you also want to remove their personal data, [purge them](/knowledge-v2/customers/common-tasks/delete-customer-data) after blocking.
</Warning>

## What Blocking Does

* Disables their active campaigns. **Stop sharing** is applied to every campaign on their profile.
* Stops them from being re-enrolled, manually or via SFTP / CSV.
* Leaves the profile readable, with a **Blocked** status pill on the side panel.

<Note>
  Blocking does **not** unsubscribe them from emails. Email opt-in is a separate flag. If you also want to stop emails, use [Unsubscribe from emails](/knowledge-v2/customers/common-tasks/turn-off-emails) on the same actions menu.
</Note>

## Unblock

Open the same profile, open the **…** menu, and choose **Unblock customer**. The status pill clears and the customer can be re-enrolled as normal.
