LinkedIn to Business Email

The LinkedIn to Business Email API retrieves the valid work email address for any LinkedIn profile. It supports single lookups (linkedin_url) and batch lookups of up to 100 profiles at once (linkedin_urls).

It only returns corporate email addresses, no personal inboxes. Use this when you need to reach contacts at their workplace domain, for example for B2B outreach, CRM enrichment, or account-based marketing campaigns. If you also want a personal email fallback, use linkedin_to_best_email instead.

Use this endpoint to:

Reach prospects at their work email address
Enrich B2B lead lists with corporate emails
Power account-based marketing and sales sequences

Fair Use Policy: This API is subject to our Fair Use Policy for Enrichment.
