We had previously required that your account address (the physical address of your company) be present in your emails through the use of our %%account_address%%. Many of your asked about more freedom in terms of the styling of that tag.
We listened! We will still pre-populate the WYSIWYG with that tag but you are now free to remove it and replace it with any formatting for your physical address. This will also allow you to use addresses for other offices or subsidiaries you may have.
Note that for CAN-SPAM compliance all emails need to have a physical address and an obvious unsubscribe link. The %%unsubscribe%% tag must still be present in all emails. As always, all emails sent through Pardot must meet these requirements and follow our permission based marketing policy.
