Add your business name and mailing address
Every marketing email legally needs a real business name and physical address. Here is why, and where to set it.
When you first set up ThunkMail, we ask for your business name and a physical mailing address. This isn't optional bookkeeping — it's a legal requirement for every marketing email you send.
Why it's required
Anti-spam laws (such as the US CAN-SPAM Act) require every commercial email to include a valid physical postal address for the sender. ThunkMail automatically adds this to the footer of every campaign, so you stay compliant without thinking about it. Because it's required on every send, we won't let you send until it's filled in.
Where to set it
- Open your Settings.
- Enter your business name and physical mailing address.
- Save. These now appear in the footer of every campaign automatically.
What address can I use?
- A real address where you can receive mail: your office, registered business address, or a PO box / mailbox service.
- It does not have to be a home address — many small businesses use a PO box or a virtual mailbox.
What else goes in the footer?
Alongside your address, every email includes a one-click unsubscribe link. Together these keep you compliant and build trust with your recipients. You can't remove them — they protect both you and your subscribers.
