#01 / DMARC + AlignmentHigh
DMARC fails for the test email
SPF passes, but the authenticated envelope-from domain does not align with the visible From domain. The DKIM signature could not be verified.
Recommendation: Configure valid DKIM signing for the sending domain or align an authenticated domain with the visible From domain.

03 / FAQ
Common questions about Email Check.
Does the test show whether every email reaches the inbox?
No. The check assesses technical authentication and DNS configuration. It cannot fully measure sender reputation, spam complaints, content, or each recipient’s filtering rules.
What should I send to the test address?
Send a new test email without confidential content through the exact sending route you want to check. Do not forward customer or business correspondence.
Do I need to pay before testing?
No. The check is free and shows up to three of the most important findings. The complete PDF with all findings and recommendations costs €29 once.
