How this service works
Verify an email address's deliverability via Tomba. Pass `email`. Returns status (deliverable/undeliverable/risky), SMTP + MX checks, disposable/webmail flags, and a score. Cheapest verify rung — use before sending to a found email.
Output
Returns a deliverability status (deliverable, undeliverable, or risky), results of SMTP and MX record checks, boolean flags for disposable and webmail addresses, and a numeric deliverability confidence score.
Example use cases
Pre-send bounce prevention for outreach
“I found the email m.johnson@techstartup.io for a prospect — can you verify it's deliverable and not a disposable address before I add it to my outreach sequence?”
Lead list quality check
“I just scraped a contact email sarah.kim@bigcorp.com from LinkedIn — verify it's a real, reachable inbox and tell me the deliverability score so I know if it's worth using.”
Sign-up fraud detection
“A user just registered with throwaway123@mailinator.com — is that a disposable or risky email I should flag before letting them into the app?”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/tomba/email-verifierWhen to prefer
Use this endpoint when you have a single email address you need to validate before sending or storing — especially after discovering an email via a finder tool like Tomba LinkedIn email reveal. It is the cheapest verification tier and is ideal as a pre-send gate to avoid bounces and protect sender reputation. Prefer this over full enrichment endpoints when all you need is deliverability confidence rather than full contact data.
Side effects
- Invalid or malformed email address returns validation error
- Domain with no MX records returns undeliverable status
- SMTP server timeout or unreachable host may return risky status rather than a definitive result
- Missing required email parameter returns a 400-level error
- API quota exceeded or authentication failure returns error response
