Domain health checker

Check MX, SPF, and DMARC before email problems reach customers

Paste a domain or email address to inspect public mail DNS records. Use this to catch missing MX, weak SPF, or non-enforcing DMARC before you verify individual inboxes or import a list.

Check a domain

Domain or email address

Paste a domain or email address to inspect public MX, SPF, and DMARC records.

This checks public DNS records. It does not verify a specific mailbox; use Verifly API checks for deliverability, disposable, role, catch-all, and mailbox signals.

Need mailbox-level verification?

DNS health only tells you whether a domain is configured for mail. Verifly checks individual addresses for deliverability, disposable domains, role accounts, catch-all behavior, and mailbox signals.
