Can I find all professional email addresses for a specific company?

Yes. Use `search_domain_emails` with a domain (e.g., 'stripe.com') or company name (e.g., 'Stripe') to retrieve all professional emails found for that organization. Each result includes the email, confidence score, position, and source URLs. Use `get_domain_email_count` to preview how many emails are available before using search credits.

Can I verify if an email address is valid before sending outreach?

Yes. The `verify_email_address` tool checks the validity and deliverability of any email address. It returns a status (deliverable, undeliverable, risky, unknown), confidence score, and details about the email server (MX records, SMTP check, accept-all detection). This prevents bounces and protects your sender reputation.

How does Hunter API authentication work?

Hunter uses an API Key passed as a query parameter (`?api_key=YOUR_KEY`) in all requests to `api.hunter.io/v2`. This differs from the typical Bearer token pattern. Your API key is available in the Hunter dashboard under Account > API. Free accounts include 25 searches and 50 verifications per month.
