How this service works
Email address -> deliverability verdict. Checks syntax, MX record presence, disposable/temp-mail domain match, and SPF/DMARC presence on the domain. Scoped to a single address, not a full domain security audit.
Output
Returns a deliverability verdict for the single email address, including: syntax validity, MX record presence on the domain, whether the domain is a known disposable/temp-mail provider, and whether SPF and DMARC DNS records are present on the sending domain.
Example use cases
Screening sign-up form submissions
“A user just registered with the email quicktoss@mailnator.com — can you verify if it's a real deliverable address or a throwaway temp-mail account before I activate their account?”
Pre-send lead list validation
“Before I send my campaign, check whether contact@prospectcorp.io is a valid deliverable email — I want to know if the domain has MX records and isn't going to hard-bounce.”
Catching fake emails in fraud review
“I'm reviewing a suspicious order and the buyer gave support@free-temp-inbox.net as their email — can you verify if that's a legitimate address or a disposable domain?”
Technical details
Endpoint
GEThttps://tariffmonkee.com/paid/email-verifyWhen to prefer
Choose this endpoint when you need a fast, single-address deliverability check that covers syntax, DNS (MX, SPF, DMARC), and disposable domain detection without performing a full SMTP handshake. Ideal for agent workflows that need to screen user-submitted emails before sending, onboarding, or storing them. Prefer it over full domain audit tools when the scope is strictly one email address and speed matters.
Side effects
- Malformed or missing email address input returns an error
- DNS timeout or lookup failure may result in inconclusive MX/SPF/DMARC checks
- Newly created disposable domains not yet in blocklists may pass the disposable check
- No guarantee of mailbox-level existence (SMTP probe not performed)
- Rate limiting or payment failure returns 402 or 429 status
