AMP Sender Registration

AMP sender registration is the review mailbox providers run before rendering AMP for Email content from a sender. It is per sending address, not per domain. Google (for Gmail) asks for SPF, DKIM and DMARC that pass and align with the From address; a real, production-quality email with an AMP part and an equivalent HTML part, sent directly — never forwarded — to its review address; a working website on the sending domain, reachable worldwide, with a privacy policy; a low spam-complaint rate; and no way for third parties to author and send email from the address. Yahoo asks for a DKIM-signed sample sent to its own review address and recommends a DMARC policy of quarantine or reject. Google says it aims to answer most requests within 5 business days. Until an address is approved, readers see the email's HTML part. MailAdx's AMP readiness steps check each requirement and prefill the registration answers, but the publisher submits the application and the decision is the provider's.
