Overview
Hunter.io is one of the most established names in email outreach, having built its reputation as the go-to tool for finding and verifying professional email addresses. The platform combines a massive database of publicly sourced business emails with powerful verification technology, domain search capabilities, and a built-in cold email campaign tool. With over 100 million indexed email addresses, Hunter.io serves as a reliable foundation for B2B sales teams and marketers looking to connect with decision-makers.
Key Strengths
Hunter.io excels in three core areas: email discovery, verification, and outreach. The Domain Search feature lets you find all publicly available email addresses associated with any company domain, complete with confidence scores and source attribution. The Email Verifier uses a multi-step process including SMTP checks, MX record validation, and catch-all detection to ensure your lists are clean. The Campaigns feature allows you to create multi-step email sequences with personalization variables, scheduling, and integrated reply tracking. All features are accessible via a robust API with native integrations for major CRMs like Salesforce, HubSpot, and Pipedrive.

The Starter plan at $49/month provides 2,000 credits and supports up to 3 email accounts for campaigns. The Growth plan at $149/month scales to 10,000 credits with 10 email accounts and advanced filtering. The Scale plan at $299/month offers 25,000 credits for larger teams.

Who Is It Best For?
Hunter.io is ideal for sales professionals, recruiters, and marketers who need reliable email discovery and verification as part of their outreach workflow. It works particularly well for teams that already have target companies identified and need to find the right contacts. Small to mid-size sales teams will appreciate the all-in-one approach that eliminates the need for separate email finder, verifier, and campaign tools.
The Bottom Line
Hunter.io remains a trusted, well-rounded platform for email-based outreach. While it lacks LinkedIn integration and phone number lookups that newer competitors offer, its data accuracy, transparent sourcing, and intuitive interface make it a solid choice for teams focused primarily on email as their outreach channel.
