An "unsubscribe link" is a mechanism typically included in marketing emails that allow recipients to opt out of further communications from a sender.
Users can click on this link to remove themselves from an email list, ensuring they no longer receive messages from the sender.
To add an unsubscribe line, you’ll have to add a short code #Unsubscribe# at the bottom of your email content.
The shortcode will be replaced by the unsubscribe link when emails are sent to your recipients.
