Free domain audit
Find the deliverability issues before they cost you sends.
Check SPF, DKIM, DMARC and MX in seconds. No account, no card, and no mailbox access required.
Public by designThis tool calls the rate-limited public audit endpoint only. It does not sign you in or read customer data.
Why this comes first
Warmup cannot fix missing authentication.
A correctly configured domain gives reputation work somewhere to land. If a blocking DNS record is missing, the audit shows what to correct before you connect a mailbox or sending service.
