Adding an unsubscribe button to HTML template

For those who create a template in third-party builders

To send a letter and provide the user with an alternative to complaining about spam, a link to unsubscribe from the mailing list should be present. You will not be able to complete editing or send a letter without it. 

Add the following line of code to your email for an unsubscribe button to appear:

<a href="{{unsubscribe_url}}">Unsubscribe</a>

Insert the line before </body>

Save the changes. Now, after a user clicks on this link, they will be unsubscribed from your mailing list.
