How this service works
Verify the deliverability of an email address.
Output
Returns a deliverability assessment for the given email address, including whether the email is valid, safe to send to, and likely to be received — along with supporting signals such as MX record status, SMTP verification result, and any flags like disposable or catch-all domains.
Example use cases
Example prompt
“Can you verify whether john.smith@acmecorp.com is a deliverable email address before I add it to my outreach list?”
Technical details
Endpoint
GEThttps://mpp.orthogonal.com/tomba/v1/email-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm that a specific email address can actually receive mail before including it in outreach, a mailing list, or a CRM. Prefer this over a syntax-only validation when you need real deliverability assurance, including SMTP and MX-level checks. Particularly useful for reducing bounce rates, cleaning contact lists, and qualifying leads.
Side effects
- Invalid or malformed email address provided — returns error indicating bad input
- Email domain does not exist or has no MX records — returns undeliverable result
- Catch-all mail server detected — deliverability cannot be confirmed definitively
- Temporary SMTP timeout or server unavailability — may return inconclusive result
- Rate limit exceeded — returns 429 error
- Authentication failure — returns 401/403 if API key is missing or invalid
