Tool guide limitationsGuides explain the intended workflow but cannot cover every device, provider or operating condition.
Interfaces and external services can change. Follow the current on-screen controls, check dates and vendor documentation, and verify important results independently before acting on them.
Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.

Common problems
- Publishing a second SPF record or an unverified report mailbox can break policy.
Privacy and security
- Only public lookup data is requested. Avoid entering internal names, credentials or confidential notes.
Worked example
- Scenario
- Drafting a monitored DMARC record
- Example input
- p=none; dmarc@example.com
- How to read it

Limitations
- The generator cannot inventory your sending platforms automatically.
Do not rely on one result for a production, security, safety, purchasing or contractual decision. Verify important findings independently.
