How email verification works

Kawaa uses a multi-layer verification process with syntax, DNS/MX, risk, and AI-assisted signals.

Verification steps

1. Syntax validation

   Check if the email follows proper format rules (RFC 5322)

2. Domain validation

   Verify the domain exists and has valid DNS records

3. MX record check

   Confirm mail exchange (MX) records are configured

4. DNS/MX and risk checks

   Validate domain mail setup and combine it with risk signals

5. Catch-all detection

   Identify domains that accept all emails regardless of validity

6. Disposable detection

   Flag temporary/throwaway email addresses

7. Role-based detection

   Identify generic addresses like info@, support@, admin@

8. AI enhancement

   Apply machine learning to detect patterns and improve accuracy

Verification confidence

Our multi-layer approach combines syntax, DNS/MX, risk, and AI signals. We continuously update our algorithms and publish measured accuracy claims only after benchmark validation.
