How this service works
Reverse-enrich an email address into a full person profile via ContactOut: name, current title/company, LinkedIn URL, work history. Pass `email` (work or personal). Use it to identify an inbound signup or reply before responding. Complements contactout/linkedin-contacts (which goes the other direction).
Output
Returns a structured person profile sourced from ContactOut, including the individual's full name, current job title, current employer, LinkedIn profile URL, and professional work history entries — all derived from a single email address input.
Example use cases
Identify inbound signup before onboarding
“Someone just signed up with the email m.johnson@techstartup.io — can you look them up and tell me their full name, current role, company, and LinkedIn before I reach out to welcome them?”
Research a reply-to email in sales inbox
“I got a reply from david.chen@enterprise.com — can you find out who this person is, what their title is, where they work, and link me to their LinkedIn profile?”
Enrich a cold outreach contact list
“I have this email address from a conference badge: sarah.kim@globalfirm.net — can you reverse-look it up and get me her full professional profile including job history so I can personalize my outreach?”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/contactout/person-from-emailWhen to prefer
Use this endpoint when you have an email address and need to identify the professional identity behind it — especially for inbound signups, cold email replies, or lead enrichment. Prefer this over LinkedIn-first lookups when the email is your only starting point. It complements the reverse direction (LinkedIn-to-email) offered by contactout/linkedin-contacts.
Side effects
- Email not found in ContactOut database — returns empty or null profile
- Invalid email format — schema validation error before request is made
- Personal email with no professional data attached — partial or empty result
- Rate limiting or quota exhaustion — HTTP 429 or payment-related error
- Network timeout if ContactOut upstream is slow — HTTP 5xx
