Headers look right.
Did one-click actually work?
Check one sanitized template before a campaign, then keep static header syntax separate from a dated, authorized no-redirect POST and removal observation. A green field check never proves DKIM validity, endpoint behavior, delivery or compliance.

Static and runtime review queue
“Evidence recorded” means the entered syntax and dated human observations are internally complete. This page did not validate the DKIM signature, send a POST, follow a redirect, inspect a subscriber record, classify the message or determine legal/platform compliance.
Mail and privacy boundary: free analysis stays in this browser. Enter only synthetic aliases and example.invalid URLs. Never paste a recipient, sender address, real domain, production unsubscribe URL or opaque ID, DKIM signature or key material, cookies, authorization, tokens, message body, production headers or logs. This page does not send mail, resolve DNS, validate DKIM, call an endpoint, verify redirect behavior, remove a subscriber, measure timing, classify a message, promise delivery or decide compliance. Authorized mail, privacy, legal and engineering owners control all production tests and decisions.
