# Redirect to Customer Website and Add Email Address to Blacklist

Using this option, you can link your unsubscribe website under the “Unsubscribe” button. The system will add your user's email address to your EmailLabs Blacklist to avoid sending them more emails.

The process of unsubscribing with redirection:

* When the user clicks on the **“unsubscribe”** button, they will be briefly redirected to EmailLabs’s website, where their email address will be added to the internal Blacklist.
* Then, the user will be directed to the specified URL with the added **\_GET”ul”** parameter, which is a sequence coded in **Base64:** \
  `message_id|e-mail|account_name_smtp.` 
* After decoding the “ul” part, you will get information in the following format: `adres@domain.coml|email@recipient.com|1.account.smtp`

* **Redirect URL:** enter the full URL address where the user is going to be redirected after clicking on the “Unsubscribe” button, then click **“Save”** to approve the changes.
* To add this URL to your emails, place the following code in the message content:\
  `<a href="##unsubscribe_link##">{{ URL name }}</a>`

Replace **{{ URL name }}** with any text representing the unsubscribe link.

**⬅️ Detailed instructions for each panel section under the "Unsubscribe' tab can be found in the drop-down menu on the left.**
