How this service works
Email validation: syntax check plus MX lookup for the domain. Input: e.
Output
Returns a validation result indicating whether the email address passes syntax checks and whether the email's domain has valid MX records, confirming the domain can receive email.
Example use cases
Pre-send email list cleanup
“Before I send out this newsletter campaign, validate the email address user@newsletter-subscriber.com — I want to make sure the format is right and the domain has working mail servers.”
User registration form guard
“Someone just signed up with the email newuser@startup.io — can you quickly check if that email address is valid and the domain can receive mail before I create their account?”
CRM data quality check
“I've got a contact record with the email sales@bigcorp.net — verify whether that email address has correct syntax and whether the domain actually has MX records set up.”
Technical details
Endpoint
GEThttps://api.discoverdmc.cloud/validate/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast email verification combining both format validation and DNS-level domain reachability (MX record check) without sending a real email. Ideal for pre-validation of user-submitted emails in registration flows, CRM cleanup, or pre-campaign list hygiene. Prefer this over pure regex-based checks since it also confirms the domain can actually receive mail.
Side effects
- Missing or empty 'e' query parameter returns an error
- Malformed email address causes syntax check to fail immediately
- Domain has no MX records — valid syntax but undeliverable domain
- DNS timeout or network error during MX lookup
- Rate limiting if too many requests in a short period
