I need a few of my templates to contain a different address than the billing address based on the audience it is reaching. Can I change the footer address in specific templates and leave the billing address in the others?
That's a great question and I'd be happy to give you the run-down here.
For those custom templates in your account, changing the address is definitely something that can be done. It does involve altering the HTML of the template so it's something that our Support team can handle for you. The best way to customize an address in the footer of a template is to send us through an email to firstname.lastname@example.org with what you need changed and which template and we can go ahead and get that all sorted for you!
As a side note, the turnaround on this is normally about a business day but can sometimes differ.
Hope that helps! Please let me know if you have any more questions on this :)
