How AI is used
Hunter.io is a lead generation and outreach tool that helps users locate professional email addresses using a company's domain or a person's name. It combines search tools with a verification system to help reduce email bounces during prospecting.
The software is designed for sales teams, marketing agencies, and small business owners who conduct cold outreach. Beyond finding emails, it includes a sequence tool for scheduling follow-ups and an AI writing assistant to help draft messages.
Buyers should consider how the credit-based system fits their volume needs, as different tasks like searching and verifying consume credits at different rates. The tool relies on publicly available web data to surface contact information.
