Email Domain Reputation Checker

When to use

Use before accepting supplier contacts, B2B outreach, and account-recovery communication.

Example checks

• Check unfamiliar business email domains in procurement.
• Review support contacts from unknown email domains.
• Validate outreach sender domains before response.

Trust signals checked

• Domain naming quality and consistency with claimed entity.
• Mailbox context trust profile for business use.
• Risk markers tied to disposable or low-trust usage patterns.

Common errors and flags

• Domain identity mismatches company claim.
• Suspicious domain patterns used for payment conversations.
• Temporary-looking domains in high-trust contexts.

FAQ

Is this the same as checking email format?

No. This focuses on domain trust context rather than syntax validity.

Can a good domain still be risky?

Yes. Always combine domain checks with message and payment-risk validation.

What should teams do on medium/high risk?

Require additional verification before accepting critical requests.
