Domain Reputation Checker

Check your domain's email reputation with a comprehensive audit of SPF, DKIM, DMARC, MX records, DNSSEC, and BIMI configuration. Get a single reputation score and actionable recommendations.

About this tool

Your domain reputation determines whether your emails reach the inbox or land in spam. This checker runs six critical tests and gives you a single score from A+ to F. It combines the results of individual checks you can also run separately: SPF checker, DKIM checker, DMARC checker, MX lookup, and BIMI lookup. If you need to fix issues, use our generators: SPF generator, DKIM generator, and DMARC generator. For a complete deliverability audit, check your deliverability score and run a blacklist check.

Frequently Asked Questions

What is domain reputation?

Domain reputation is a score that email providers (Gmail, Outlook, Yahoo) assign to your domain based on your sending history, authentication setup, complaint rates, and other factors. A good reputation means emails reach the inbox. A bad reputation means they go to spam.

How is the reputation score calculated?

Our score weights six factors: SPF (25%), DKIM (25%), DMARC (25%), MX records (15%), DNSSEC (5%), and BIMI (5%). Each check scores 0-100 based on the quality of configuration. The weighted average produces your overall score from A+ (90+) to F (below 50).

Why is DKIM harder to detect?

DKIM records are stored under specific selectors (e.g., selector1._domainkey.example.com). We check common selectors used by major providers, but your domain may use a custom selector. A 'not found' result for DKIM does not necessarily mean DKIM is not configured.

What is a good domain reputation score?

Aim for 80+ (grade A or A+). This means your SPF, DKIM, and DMARC are properly configured. Scores below 60 indicate critical gaps that likely affect your email deliverability.

How often should I check my domain reputation?

Check monthly or whenever you make DNS changes, switch email providers, or notice deliverability issues. Also check after setting up a new sending domain or subdomain.

Does this tool check if my domain is blacklisted?

This tool focuses on DNS-based email authentication. For blacklist checks, use our dedicated blacklist checker tool which queries major DNSBLs and spam databases.
