Email finder and verifier for sales, recruiting, and outreach teams that need accurate professional contact data.
Email finder and verifier for sales, recruiting, and outreach teams that need accurate professional contact data.
Hunter.io is a long-running email discovery and outreach platform built around a simple promise: give it a company domain, and it returns the verified professional email addresses associated with that company, along with the names, job titles, and source URLs where each address was found on the public web. The platform has grown from a niche email-lookup utility into a full cold outreach stack used by more than six million professionals across sales, recruiting, partnerships, journalism, and link building.
At the core of the product is the Domain Search, which crawls publicly available web pages and uses pattern-based prediction to surface every email associated with a given organization, ranked by confidence score. The Email Finder takes a person's name plus a company and returns the most likely address using the company's detected pattern (first.last, firstletter+last, etc.) validated against Hunter's 100M+ email database. A companion Email Verifier checks any address for deliverability through syntax validation, domain checks, and mail server testing — useful for cleaning imported lists before sending.
Hunter's built-in Campaigns module connects directly to Gmail or Outlook accounts and supports multi-step sequences with A/B testing, custom scheduling, link tracking, and automatic reply detection. While it lacks the advanced deliverability infrastructure of dedicated cold email platforms (no inbox rotation, no built-in warmup), it's sufficient for small teams running moderate-volume outbound without subscribing to a separate sending tool.
Pricing starts at $0/month with 50 search credits, scaling through Starter ($34/month billed yearly), Growth ($104/month billed yearly), and Business ($209/month billed yearly) tiers. All plans include unlimited team members and a polished Chrome extension that surfaces verified emails directly from LinkedIn profiles and company websites. The platform integrates with Salesforce, HubSpot, Pipedrive, Zapier, Make, and Google Sheets, and offers a clean REST API for custom enrichment workflows.
Hunter differentiates itself through data transparency — every email returned includes the public source URL where it was found — and a straightforward unified credit system where one credit equals one search or find operation. This simplicity, combined with a genuinely useful free tier, makes it the default starting point for professionals who need verified B2B email addresses without committing to an enterprise sales intelligence platform.
Was this helpful?
Hunter.io is the most focused and reliable tool for finding and verifying professional email addresses, trusted by 6M+ users. The Chrome extension is best-in-class for prospecting from LinkedIn. The platform has evolved into an all-in-one outreach tool with campaigns, a B2B database, and AI writing assistance, making it viable as a single tool for small sales teams. Limitations include weaker international coverage, basic campaign features compared to dedicated cold email platforms, and a smaller prospect database than Apollo or ZoomInfo. For teams that primarily need verified emails with clean pricing, Hunter remains the go-to choice.
Discovers all known email addresses at a company domain by crawling public sources, returning contacts with names, job titles, departments, and confidence scores alongside the company's email pattern.

Predicts a specific person's professional email address using their first name, last name, and company domain, applying pattern analysis and verification with confidence scoring.
Use Case:

Through 2025 and into 2026 Hunter has continued to expand its data network and tighten its outreach stack: improved Campaigns deliverability with smarter sending logic and time-zone-aware delivery, refined the Chrome extension with better LinkedIn integration, expanded the integrations marketplace (deeper Salesforce and HubSpot syncing, new Pipedrive and Zoho workflows), and continued to invest in AI-assisted personalization for cold sequences. The company also maintains its public stance on data ethics, citing source URLs for every email surfaced — a position that has aged well as GDPR and CCPA enforcement has intensified in the prospecting category.
