How this service works
Email check: validates the address format, confirms the domain exists and accepts mail (MX), and flags disposable providers, role accounts (info@, support@), and free providers. Returns deliverable_likely, risky, undeliverable, or invalid with a reason. No message is sent. Useful for cleaning sign-up lists and lead data before outreach.
Output
Returns a structured verdict with one of four statuses — deliverable_likely, risky, undeliverable, or invalid — along with a human-readable reason explaining the classification (e.g. disposable provider detected, no MX records found, role account, free provider, malformed address). No email is sent during the check.
Example use cases
Sign-up form email gating
“Before we create an account for the user, check if the email they submitted — noreply@guerrillamail.com — is deliverable and whether it's a disposable or role address we should reject.”
Lead list hygiene before outreach
“I have a new lead with email info@somestartup.io — can you verify whether it's actually deliverable and flag it if it's a generic role account or from a throwaway domain before we add it to our sales sequence?”
CRM data quality audit
“Run a deliverability check on support@mailinator.com and tell me if it's valid, risky, or undeliverable — and why — so I can decide whether to keep it in our CRM.”

Endpoint
POSThttps://verifylite.hydratinghealingtouch.workers.dev/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, real-time email validation check that goes beyond simple format regex — specifically when you want to catch disposable providers, role accounts, and non-mail-accepting domains before sending any outreach or creating accounts. Prefer it over full verification services that send probe emails when you want zero side effects and fast results. Ideal for sign-up flows, lead ingestion pipelines, and CRM hygiene where sending a test message is unacceptable.
Side effects
- Missing or empty email field returns an invalid status with a format error reason
- Malformed JSON in request body returns a 400-level error
- Domain exists but has no MX records returns undeliverable
- Transient DNS lookup failure may return an error or ambiguous result
- Newly registered domains may not yet be recognized as legitimate, producing false positives
