The link must appear within the email, regardless of whether it is placed in the header or at the very end.
The link text must be clear and unambiguous.
The color of the link must not conceal the link within the email.
The font size of the link must be sufficiently large and proportional to the rest of the text.
Unsubscribing must be free of charge and without conditions.
Good to know: the unsubscribe link is not mandatory for transactional emails that directly contribute to the proper functioning of the expected service (order confirmation, shipping notice, expiration of a means of payment, etc.).
After typing the text that will serve as the unsubscribe link, select this same text.
Click on the chain icon, which will allow you to identify the text as a link.
In the “Type” drop-down list, select “To an unsubscribe form”.
In the “Method” drop-down list, choose the part of the page that will allow your recipient to unsubscribe independently.
