I am using CiviCRM 5.18.4 with WordPress 5.3.2, and residing in the United States, where we are required by law to include certain info (our postal address and an opt-out link) in ALL our emails. I can do this in my individual messages and bulk email footers, fine. But they don't show up in any of the Mailflow messages.
I have tried adding
{$domain.address}
<p>To comply with CAN-SPAM laws, we remind you that you can also opt-out of all mailings from us. To do so, <a href="{$action.optOutUrl}" click here</a>, or send mail to {$action.optOut}. </p>
near the bottom of the (html) message template, but it doesn't plug in the token values (or it just generates a critical error).
But even if I could get it to work, why am I figuring out how to tweak this? Doesn't almost EVERYONE need to include a footer like this in almost ALL their workflow emails?
