Free domain health tool
Check email health for any domain.
Review MX records, SPF, DMARC, provider signals, and disposable-domain risk before trusting a domain for email validation or outreach.
Receiving setup
MX records show whether a domain is configured to receive mail and which provider handles routing.
Sender trust
SPF and DMARC help receiving systems evaluate whether messages are authenticated.
Validation context
Domain health does not prove a mailbox exists, but it gives useful context before validating individual emails.
Need mailbox-level scoring?
Run a full EmailCheq validation to combine domain signals with syntax, typo, disposable, role-inbox, and address-level checks.
