💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
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.
