Check your domain’s SPF, DKIM and DMARC

These three records decide whether Gmail, Outlook and others trust the mail you send as your domain. Type your domain to see what it publishes and what to fix.

My sending service has its own DKIM selector

DKIM keys are found by a name your sending service chooses, so we try the common ones. If yours is not found, type the selector the service shows you.

We read your domain’s public DNS records and do not store the domain or the result.
