Explore the key features that make Hunter.io powerful for sales & marketing agents workflows.
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.
An SDR targeting a mid-market SaaS company runs Domain Search to find all marketing and sales contacts, identifying the VP of Marketing and three team members for a multi-threaded outreach approach.
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.
After identifying a decision-maker on LinkedIn, a sales rep uses Email Finder to get their verified email address and immediately adds them to a targeted outreach sequence.
Validates email deliverability through syntax checks, domain verification, and mail server testing, returning accept-all detection and deliverability status to minimize bounces.
Before launching a campaign to 5,000 trade show leads, the marketing team bulk-verifies the list to remove invalid addresses and protect their domain sender reputation.
Built-in email sequencing platform with multi-step sequences, A/B testing, link tracking, reply detection, and scheduling — integrated directly with the discovery and verification tools.
A startup founder discovers 200 target prospects via Domain Search, verifies their emails, and launches a 3-step cold email sequence — all without leaving Hunter's platform.
Built-in B2B contact and company database with filters for industry, company size, job title, location, and technology stack, providing prospecting without a separate data provider.
A sales team filters for CTOs at Series B SaaS companies in the US with 50-200 employees, building a targeted prospect list directly in Hunter without needing ZoomInfo or Apollo.
Browser extension that surfaces email addresses from LinkedIn profiles, company websites, and professional directories with one click, showing verification status and confidence scores.
During a LinkedIn prospecting session, an SDR clicks the Hunter extension on each target profile, instantly seeing their verified email address without context-switching to a separate tool.
Hunter uses a unified credit system: 1 credit = 1 email found via Domain Search, Email Finder, or Bulk Email Finder. Verification uses separate verification credits. The Free plan includes 50 search credits/month. Starter ($34/mo billed yearly, $49/mo billed monthly) includes 2,000 search credits/month. Growth ($104/mo billed yearly, $149/mo billed monthly) includes 10,000 search credits/month. Business ($209/mo billed yearly, $349/mo billed monthly) includes 25,000 search credits/month. All plans include unlimited team members.
Accuracy depends on the confidence score returned with each result. Emails with 90%+ confidence scores consistently deliver 95%+ accuracy in real-world testing. Scores of 70-90% are suitable for bulk campaigns where some bounces are acceptable. Below 70%, always verify separately. Hunter finds emails through public source analysis and pattern prediction — it's strongest for companies with discoverable email patterns.
For small teams doing basic cold email, yes — Hunter now includes multi-step sequences, reply tracking, A/B testing, and scheduling. But for teams needing advanced features like multi-channel outreach (email + LinkedIn + phone), advanced personalization variables, inbox rotation, or warm-up tools, dedicated platforms like Instantly, Lemlist, or Outreach offer significantly more capability.
Hunter sources emails exclusively from publicly available information (websites, social profiles, directories), which generally falls under legitimate business interest for B2B outreach under GDPR. Hunter provides data source transparency showing where each email was found, supports deletion requests, and stores data on EU servers. However, compliance responsibility ultimately falls on you — consult legal counsel for your specific use case and jurisdiction.
Hunter focuses specifically on email discovery and verification with best-in-class accuracy for found emails. Apollo and ZoomInfo are comprehensive B2B databases with phone numbers, intent data, org charts, and multi-channel engagement platforms. Hunter is cheaper and simpler for teams that primarily need verified emails. Apollo/ZoomInfo is better for enterprise teams needing full-stack sales intelligence.
Now that you know how to use Hunter.io, it's time to put this knowledge into practice.
