Hunter.io review 2026: email finder and verifier pricing, credit-based plans, deliverability accuracy, integrations, pros and cons, and best alternatives.
Hunter is an email finder and verifier built to solve one specific problem for sales, marketing, and recruiting professionals: quickly and reliably determining a person's professional email address at a given company. Founded in 2015 by Antoine Finkelstein and François Grante, the company has grown into a widely used prospecting tool without ever raising outside venture funding, operating instead as a lean, fully remote, self-funded business.
The product's underlying database is built from publicly indexed data across roughly 81 million websites, which powers its core Domain Search and Email Finder features. Users can search by company domain to see every publicly associated email pattern and contact, or search by a specific name and domain to generate the most likely email address, which is then checked for deliverability through Hunter's Email Verifier.
Hunter is delivered as a web app, a Chrome extension, a Google Sheets add-on, and a full REST API, making it easy to slot into existing prospecting and CRM workflows rather than requiring teams to change how they already work.
Hunter's core toolset centers on Domain Search, which returns every email address pattern and publicly associated contact for a given company domain, and Email Finder, which predicts a specific person's most likely email address given their name and company. Both are backed by the Email Verifier, which checks syntax, domain validity, and mailbox deliverability to reduce bounce rates before a user sends outreach.
For teams running structured outreach, Hunter Campaigns adds the ability to build and send simple cold email sequences with follow-ups and open tracking directly from the platform, reducing the need for a separate sales engagement tool for smaller-scale outreach.
Integration depth is a major part of Hunter's value: the platform connects natively to HubSpot, Salesforce, Pipedrive, and Zapier, and exposes a full API for teams building custom prospecting or enrichment workflows, alongside a widely used Chrome extension for finding contacts directly on company websites and LinkedIn.
Hunter uses a straightforward credit-based pricing model across five tiers. The Free plan includes 50 credits per month with no credit card required, letting individuals and very small teams try the product with no commitment. Paid tiers start at the Starter plan, priced at $49 per month billed monthly or $34 per month billed annually, and scale up through Growth at roughly $104 per month and Scale at roughly $244 per month with annual billing, each unlocking more monthly credits, higher API limits, and additional seats.
One credit finds an email via Domain Search or Email Finder, while verifying an email costs half a credit, and unlimited team members are included on every paid plan rather than being charged per seat. Annual billing applies a flat roughly 30 percent discount versus monthly pricing across all tiers, and an Enterprise plan with custom pricing and contract terms is available for larger sales and revenue teams that need higher volume or dedicated support.
