## When to prefer this

Use this endpoint when you need to find a specific individual's professional email address given their name and company domain or LinkedIn handle. Prefer this over Domain Search when you have a specific person in mind rather than wanting all emails at a company. Use when building targeted outreach lists, enriching CRM records with contact emails, or verifying contact information for a known individual.

## Known failure modes

- Email not found for the given name and domain combination — returns empty or null result
- Invalid or non-existent domain provided — returns error or no results
- Insufficient identifying information (e.g. only last name without domain) — returns validation error
- Rate limit exceeded — returns 429 error
- Max duration timeout reached before email could be found — returns partial or no result
- LinkedIn handle not recognized or inaccessible — returns no result

## How this service works

## Output

Returns a found professional email address for the specified person at the given company domain, typically including a confidence score, the source of the email, and associated metadata such as the person's full name and company.
