How to add custom email footers for all emails?
Sometimes you might need to make sure all the emails that go out will contain a certain email footer, for example where you’ll add the default unsubscribe information, or maybe your copyright.
In order to do so, you have to navigate to Backend > Settings > Customers > Campaigns and populate the Email Footer box with your own content.
Please note that this can be further customised for each customer group, from the same Campaigns tab, this representing the default value for that tab.
If you decide to insert the unsubscribe tag in your email footers, you most likely will want to make it optional for email templates. In order to do so, you have to follow this article that shows how to make tags required or optional.
