The footer in your campaign uses a personalization tag to insert the physical mailing address of your organization. You may see the tag listed as %SENDER-INFO% or as %SENDER-INFO-SINGLELINE%:

Once the campaign is sent to contacts, your physical mailing address will replace the tag in your email:

The address displayed will be the same one you marked as the default address on the Settings > Addresses page in your account. However, you can choose to display a different physical mailing address when you need to. Note that this can be done for both campaigns and automation emails.
In this article, we'll show you how to change the physical mailing address that appears in the footer of your email.
1. From the Campaigns Overview page, click "Continue" for the campaign you wish to update
the address for.
2. Click "Summary" from the top menu to go to the Campaign Summary page.

3. In the address section, you'll see a dropdown. The address selected here will be the same
address that will display in your email's footer once it's sent. To use a different address, click
the dropdown.

4. Now you can choose to use a different mailing address by clicking it from the list of options.
Or you can add a new address on the spot by clicking "Add New Address."

If you choose to add a new address, a pop-up window will appear. Complete the information
in the window and click "Add." The new address will be selected in the dropdown
automatically.

Once you've finished selecting a different address to display in your email, you can click "Save & Exit" at the top so you can come back to your email later. Or if you're ready to send the email, you can click "Send Now" or schedule it to send at a future date and time.
You can only make this update for campaigns that have a "Draft" or "Scheduled" status. It is not possible to use a different mailing address for campaigns with a "Sent" status.
This update can be made to automation emails at any time. All contacts who are sent this campaign after you make this change will see your updated physical address.
