Hunter

Hunter (hunter.io) is an AI-powered email prospecting platform trusted by over 6 million users worldwide. Its core capability is Domain Search — enter any company domain and Hunter returns professional email addresses it has found publicly, alongside the exact source URL where each email was discovered. This source transparency is unique in the email finder market. As of 2025, Hunter has unified its credits into a single pool and added a native MCP server, making it the first major email finder to integrate directly with AI agents and LLM-based workflows.

Hunter operates across three stages: finding contacts (Domain Search, Email Finder, Bulk tasks), verifying them (multi-step Email Verifier), and reaching them (Campaigns with personalized sequences, AI Writing Assistant, automated follow-ups). The entire workflow runs inside Hunter without requiring a separate outreach tool for core cold email operations.

How Hunter Works as an AI Agent

Paste a company domain and Domain Search returns all associated professional emails with confidence scores, department labels, and public source links. Email Finder predicts a specific person's email from their name and company domain. Both feed into the Campaigns module, which sends personalized cold email sequences with automated follow-ups, open tracking, link tracking, and A/B testing. The AI Writing Assistant generates email copy for sequences. The MCP server lets external AI agents and LLMs call Hunter's Email Finder and Verifier directly — enabling fully automated AI-driven prospecting pipelines.
