Permission-Based Email Deliverability Review
Review sender authentication, alignment, message headers, unsubscribe handling, and monitoring against provider-specific evidence.
When to use it
A team is investigating authentication warnings, spam placement, rejection, or a sender-domain change.
Prepare these inputs
Sending domains and providers, message type, recipient-provider volume, current DNS, and sanitized headers from an authorized test message.
A practical workflow
- 01
Scope the receiving service, account type, message class, and volume to that provider. Do not conflate Gmail personal with Workspace or Outlook.com with Microsoft 365.
- 02
Inspect SPF, DKIM, and DMARC for the actual sending identity; compare the visible From domain with authentication and alignment results.
- 03
Read results from an authorized received test message and unsubscribe headers where applicable. DNS presence alone does not prove a message passed.
- 04
Review permission source, exclusions, unsubscribes, complaints, and bounces; route legal questions to qualified counsel.
- 05
Record what was and was not tested, assign an owner, and define how findings will be rechecked.
What the toolkit includes
A provider-specific reference matrix, sanitized evidence capture, review report, and diagnostic cases.
Review boundaries
Provider rules change; verify official guidance for the exact recipient service and message class. Authentication does not guarantee inbox placement.
