If you wish to send an automation email to contacts, or a test version of the email to yourself, you may see two warnings in two different places (Campaign Summary page and Automation Builder) letting you know that you need to provide a physical mailing address on your email. Both warnings provide buttons to click that will redirect you to the Settings>Address page where you can add this information. All outgoing emails are required by law to include a physical mailing address. If this information is not added, then emails will remain in draft mode and will not send.
