How this service works
Verify the deliverability of an email address.
Output
Returns a verification result indicating whether the email address is deliverable, along with details such as validity status, format check outcome, domain/MX record status, and whether the mailbox exists.
Example use cases
Pre-send bounce prevention
“Before I send out this campaign, can you verify that sarah.jones@acmecorp.com is a valid, deliverable email so I don't waste a send on a bad address?”
CRM lead validation
“I just got a new lead with the email address mike.smith@techstartup.io — can you verify it's real and will actually receive mail before I add it to our CRM?”
Sign-up fraud detection
“A user just registered with the email address freemail123@disposable.xyz — can you check if that email address is deliverable and legitimate?”
Technical details
Endpoint
GEThttps://x402.orthogonal.com/tomba/v1/email-verifierWhen to prefer
Use this endpoint when you need a quick, per-email deliverability check powered by Tomba's verification infrastructure and are willing to pay $0.01 USDC per call via the x402 payment protocol. Prefer this over bulk validation tools for single-address spot checks, CRM hygiene, or pre-outreach validation in an agent workflow.
Side effects
- Invalid or malformed email address provided — returns an error or invalid status
- Email domain does not exist or has no MX records — flagged as undeliverable
- Catch-all mail servers may cause inconclusive results
- Rate limiting or payment failure may block the request
- Temporary SMTP errors on the recipient server may lead to unknown status
