Mail Delivery Check
Send a test email (from the same system you use in production) to the unique address below. After it arrives, click "Check your score". We analyse SPF, DKIM, and DMARC from the message headers and DNS. The message is then deleted. You can download the report. No data is stored beyond the check.
After clicking, we check the mailbox for an email to the address above. If found, it is evaluated and then deleted.
Why test email deliverability?
You send a test email to our system; we receive it and analyse how it was authenticated. Use this to improve inbox placement and fix SPF/DKIM/DMARC issues.
What is checked?
SPF (Sender Policy Framework) is checked against the delivering server IP from the Received headers (not your PC). DKIM and DMARC results come from the receiver's Authentication-Results and from DNS. We also show which IP was used for the checks.
