Hunter

What this skill does

Hunter is an email finding and verification platform designed to streamline outreach and link building efforts. It enables marketers to search for email addresses associated with specific domains, locate individual contacts by name, and verify the deliverability of email addresses to reduce bounce rates. The platform offers a REST API that supports domain searches, email lookups, and verification, making it suitable for integration into automated workflows and lead generation systems.

With a free tier allowing 25 searches and 50 verifications per month, Hunter helps performance marketers identify valid contacts quickly and maintain clean email lists. This improves campaign targeting and conversion rates by reducing wasted outreach to invalid or outdated addresses.

Who it's for

Hunter is ideal for growth leads and agency strategists focused on link building and cold outreach campaigns. SEO professionals looking to identify domain-level contacts for backlink acquisition will find its domain search and verification capabilities particularly useful. It also serves email marketing operators who need to validate large lists to improve deliverability and reduce spam complaints.

This skill suits practitioners managing lead generation where accurate contact information is critical, especially those balancing manual research with automated processes to scale outreach efforts efficiently.

Key workflows

A typical workflow begins with a domain search to retrieve email addresses tied to a target website, helping build a relevant contact list. Next, users can perform individual email lookups by specifying a first and last name alongside the domain to find specific decision-makers or influencers. Verification of email addresses follows to ensure contacts are active and reduce bounce rates in outreach campaigns.

Users also manage leads by adding or removing contacts and can organize outreach efforts through campaign management features that allow starting, pausing, or reviewing email sequences. Monitoring account usage helps optimize API calls within the monthly limits and avoid rate limiting during high-volume operations.

Common questions

How accurate is Hunter’s email verification? Hunter uses a combination of syntax checks, domain validation, and mail server response analysis, providing reliable deliverability signals to minimize bounces. Can I find emails for any company domain? Most public domains with online presence are supported, but results depend on available data and privacy restrictions. What are the rate limits? The free plan allows 25 searches and 50 verifications per month with an API limit of 10 requests per second, which scales with paid tiers.
