What is a List-Unsubscribe header?

List-Unsubscribe is an email header that gives inbox providers a machine-readable way to offer an unsubscribe option at the top of a message. It can point to a URL, a mailto address, or both, and it improves deliverability and user trust.

What does CAN-SPAM require for unsubscribing?

The US CAN-SPAM Act requires a clear, working opt-out mechanism in every commercial email and that you honor unsubscribe requests within 10 business days. You may not charge a fee, require more than an email address, or make the recipient take extra steps to opt out.

Do Gmail and Yahoo require one-click unsubscribe?

Yes. Since 2024, Gmail and Yahoo require bulk senders to support one-click unsubscribe via the List-Unsubscribe and List-Unsubscribe-Post headers and to process opt-outs within two days. Including the header helps meet these bulk-sender rules.

What should an unsubscribe email include?

It should clearly confirm the opt-out request, identify the sender, and require nothing more than the recipient's email address. Keeping it short and honoring the request promptly keeps you compliant and protects your sender reputation.
