Do I need a Hunter.io account to use this skill?

Yes, you need an active Hunter.io account and an API key. You will be prompted to connect your account via the Composio MCP server during setup.

How accurate is the Email Finder tool?

The tool uses Hunter's proprietary algorithms to infer the most likely email address. You can increase accuracy by setting a higher 'max_duration' parameter to allow for deeper verification.

Can I filter email searches by department or seniority?

Yes, the Domain Search tool supports advanced filtering for seniority levels like 'executive' or 'senior' and specific departments such as 'sales', 'finance', or 'it'.

Does checking email counts consume my API credits?

No, the email volume estimate tool is a free call that does not consume your Hunter.io search or verification credits, making it ideal for initial prospecting.
