How this service works
Validate an email address: syntax, MX resolution, disposable-domain check.
Output
Returns a validation result indicating whether the email address passes syntax checks, whether the domain has valid MX records for mail delivery, and whether the domain is recognized as a disposable or temporary email provider.
Example use cases
Block disposable signups at registration
“Before we create an account, check if 'user123@mailinator.com' is a real email or a throwaway disposable address — I want to block fake registrations.”
Validate lead email before CRM import
“I have a new lead with the email 'contact@acme-corp.io' — can you verify it's syntactically correct and that the domain actually accepts mail before I add it to the CRM?”
Scrub mailing list before campaign send
“Check if 'newsletter_sub@guerrillamail.com' is a valid, deliverable email address — I don't want to waste campaign sends on broken or disposable inboxes.”
Technical details
Endpoint
POSThttps://email-verification.nordman-tehau.workers.dev/verifyWhen to prefer
Choose this endpoint when you need a lightweight, per-call email validation that covers syntax, DNS/MX reachability, and disposable-domain detection in a single API call. Ideal for agent workflows that need to gate on email quality before sending communications, storing user data, or importing leads — especially when you want a pay-per-use model without a subscription.
Side effects
- Malformed input (missing email field) returns a 400 error
- DNS timeout or MX resolution failure may result in inconclusive deliverability status
- Disposable domain list may not cover newly created throwaway services
- Valid-looking syntax on a non-existent domain may pass syntax check but fail MX resolution
- Payment failure via x402 protocol results in 402 response before verification occurs
