Used For

• +**Your LinkedIn searches hit 'connect to message' walls and you need actual email addresses** → Type in company domain, get 100+ verified emails with confidence scores in seconds
• +**You're sending cold emails that bounce 30-50% and killing your Gmail reputation** → Bulk verify lists of 1,000+ addresses before hitting send, drop bounces to under 5%
• +**Manual prospecting eats 20 hours/week of your SDR's time** → Domain search finds decision-maker emails instantly instead of tab-switching between LinkedIn, company sites, and email guessers
• +Chrome extension works right from LinkedIn profiles - hover over someone's name and get their verified email
• +Campaigns tool sends personalized sequences with A/B testing so you're not just blasting the same template

Best For

• >Your sales team wastes entire afternoons guessing email formats and getting bounces
• >You're manually scraping LinkedIn profiles and company websites for contact info
• >Cold emails bounce 40% of the time and you're scared of ruining your sender reputation

Not For

• -Solo freelancers doing under 50 leads per month — you'll hit the free tier limits in two days and manual Google searches are honestly faster
• -Enterprise teams sending 10,000+ emails daily — lacks advanced compliance handling and GDPR auto-features you'll need
• -Anyone wanting phone numbers or deep company data — this is email-only, no enrichment like revenue or employee counts

Pairs With

• *HubSpot (where you import the verified leads and actually manage the sales pipeline)
• *Google Sheets (for exporting lead lists and organizing your prospecting data before campaigns)
• *Gmail (connects directly for sending cold email sequences without switching platforms)
• *Salesforce (to sync found contacts into your actual CRM instead of living in Hunter forever)
• *Zapier (automates the lead flow from Hunter searches into your CRM and email tools)
• *LinkedIn Sales Navigator (where you find the prospects, then use Hunter to get their actual email addresses)

The Catch

• !Free tier's 25 searches vanish in 2 days for active users, then you hit the paywall hard
• !Campaign sends eat through your quota fast — users report hitting the 500 email limit in week 1 on Starter plan
• !Overages are sneaky at $0.01 per verification and add up quick when you're bulk checking large lists

Bottom Line

Turns 4 hours of manual email hunting into 30 minutes of actual results.
