What every email must include
The two things every campaign footer needs before it can send: an unsubscribe link and your mailing address.
Every campaign needs two things in its footer before it can send: a working unsubscribe link and your postal mailing address. Anti-spam laws like CAN-SPAM require both in marketing email, so EmailFig checks for them before you send.
Gallery templates, and any campaign you start from scratch, already have both. If you rework the footer yourself, keep them: removing either one blocks sending.
The two footer tags
Both are merge tags: placeholders that EmailFig fills in for each person when the email goes out.
{{ unsubscribe_url }}: the Unsubscribe URL merge tag. Links the reader to your unsubscribe page.{{ account.physical_address }}: the Mailing address merge tag. Prints the address you’ve set for your account.
To add either, use the merge tag menu in the Content step’s editor.
To set the address, go to Settings → Unsubscribes and fill in Mailing address. A street address, registered P.O. box or private mailbox all work.
If one’s missing
What’s left on the Review step names exactly what’s missing: “Add {{ unsubscribe_url }} to the footer”, “Add {{ account.physical_address }} to the footer” or “Add a mailing address in settings”. See Why the Send button is disabled.
