## Test a real email

See what receiving servers see. Create a temporary test address and send a normal email from the domain you want to check.

## Understand the result

Clear checks, without the guesswork. Read the SPF, DKIM and DMARC results, identifier alignment and published SPF and DMARC records.

## Know what to fix

Practical next steps for your domain. Use the report to identify authentication and alignment issues. Authentication does not guarantee inbox placement.
