What you get

Deliverability

Live MX/DNS lookup tells you whether the domain can actually receive mail.

Disposable detection

Flags temporary/burner mailbox domains that pollute your list.

Role accounts

Identifies shared inboxes like info@ and support@ that hurt deliverability.

Typo suggestions

"did you mean gmail.com" — recover customers who fat-finger their address.

Normalization

Gmail-aware canonical form so you can dedupe dots and +tags.

Batch + score

FAQ

What does emailcheck sell?
A metered HTTP API. You send an email address; we return a structured validation verdict. Billing is per monthly request quota.
Do you send email to verify?
No. We check syntax, classification, and MX/DNS records — no SMTP probing, so we never message the address.
How do I get access?
Subscribe above for a direct API key, or find us on the RapidAPI marketplace.
Do you store the addresses I check?
No. Addresses are validated in-request and not retained.
