Start an async professional-email extraction job for one or more contacts. Returns job_id. Prefer linkedin_url when available; otherwise provide first_name + last_name + company_name or company_domain. Optionally pass boomerang_identity_id when the Boomerang contact id is known. After calling, poll getEmailExtractionJobStatus until the job is terminal — results (including emails) are returned on that same status response.

Use when: Use when you need to find a contact's work email and do not already have it. For a single person, pass one contact. Do not invent emails — wait for the job to complete.

workspace_id / user_id are injected from request headers.

Next steps (after this tool succeeds): [REQUIRED] [ACTION] → call getEmailExtractionJobStatus: Poll getEmailExtractionJobStatus with the returned job_id until status is COMPLETED, PARTIALLY_COMPLETED, or FAILED, then read results[].email.
