### `resolve_personal_email_employer` (~424 tokens)

Resolve the employer behind a personal email

Find the likely employer behind a free mail address (Gmail, Outlook, iCloud, Yahoo, and about 140 more), from the public Gravatar profile for the address, the GitHub account whose public commits are signed with it, and Mamba Labs Person LinkedIn URL Resolver. Returns one row per address with person_name, employer_name, employer_domain when a source names it, employer_source, employer_confidence from 0 to 1, match_status (resolved at 0.75 or more, weak, name_only, corporate_email, not_found, invalid_email, blocked), the LinkedIn URL when found, and evidence_urls. It never contacts the mailbox and never opens LinkedIn. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN; Apify charges per resolved address, and the optional LinkedIn step is billed by Person LinkedIn URL Resolver at its own price.

Input parameters:

- `country` (string): Two letter Google country code. Default us.
- `email` (string): One email address, for example a signup on a Gmail address.
- `emails` (array): Several addresses, up to 300. A company address returns its own domain, free.
- `github_token` (string): Optional. Your own free GitHub token, for batches over about 25 addresses. Used for this run only and never stored.
- `max_charge_usd` (string): Optional. The run stops before a charge that would pass this amount; it is passed to the LinkedIn step too.
- `search_web` (string): true adds one exact Google search for an address that Gravatar and GitHub leave without an employer. Default false.
- `use_linkedin_resolver` (string): true (default) runs Mamba Labs Person LinkedIn URL Resolver from your account for the addresses with a name and an employer, billed at that actor's own price per person sent to it, found or not (0.03…
