Check your domain's email deliverability score in one click. Free email infrastructure grader that checks SPF, DKIM, DMARC, and mail server configuration.
Domain email health check
This free email deliverability score checker runs four checks against your domain. It verifies your SPF record (which servers are allowed to send email for you), your DKIM record (which proves emails have not been tampered with), your DMARC policy (which tells receiving servers what to do with unauthenticated email), and your MX records (which confirm your domain can receive email).
Each check scores up to 25 points. A perfect score means all four are properly configured. Most cold email deliverability problems trace back to one or more of these being missing or misconfigured. You can check each one individually with our SPF checker, DKIM checker, or DMARC checker.
Your email infrastructure score is calculated from four equal components. SPF, DKIM, DMARC, and mail server each contribute 25 points to your total score out of 100. A full pass on each check gives you the maximum points. Partial configurations (like having an SPF record with a soft fail policy instead of a strict one) earn partial points. Missing records earn zero.
Scores above 80 indicate solid email infrastructure. Between 50 and 79 means you have gaps that could hurt deliverability. Below 50 means your emails are almost certainly hitting spam folders.
Gmail, Microsoft, and Yahoo all check SPF, DKIM, and DMARC before deciding where to put your email. If any of these are missing, your messages get flagged. If you are sending cold email without proper authentication, you are asking spam filters to penalize you.
This matters even more if you are using shared sending pools. When another sender on the same infrastructure gets flagged, your deliverability drops too. That is why owning your own sending infrastructure through services like AWS SES gives you control over your reputation. EmailQo connects to your own AWS SES account and handles the setup without requiring a technical team. Check our spam checker to test your email content as well.
Start with the checks that failed. If your SPF is missing, add a TXT record to your DNS. If DKIM is not configured, set it up through your email provider or AWS SES. If DMARC is missing, create a basic policy record. Each fix takes a few minutes in your DNS settings.
If you want this handled automatically, EmailQo monitors your email infrastructure and runs these checks before every campaign send. Problems get caught before your emails go out, not after your open rates drop. Plans start at $19/mo with a 7 day free trial.
