Frequently Asked Questions

What makes Mailsfinder the best email finder tool? expand_more

Mailsfinder offers 100K credits at $99/mo with 99% accuracy — far more than any competitor at comparable pricing. Every email is verified in real-time using SMTP handshake verification, not pattern guessing or cached databases. Plus, you get full API access, bulk CSV processing, and integrations with n8n, Make, Zapier, and Google Sheets all included.

How does Mailsfinder compare to Hunter.io? expand_more

Mailsfinder gives you 50x more credits at comparable pricing. Hunter offers 2,000 credits for $49/mo, while Mailsfinder delivers 100,000 credits for $99/mo. That's $0.001 per email vs Hunter's $0.024. Mailsfinder also uses real-time SMTP verification instead of Hunter's pattern-based approach, resulting in significantly lower bounce rates.

Is Mailsfinder better than Apollo for email finding? expand_more

Apollo offers unlimited* email credits but relies on a cached database, which means email data can be outdated. Mailsfinder verifies every email in real-time using SMTP handshake, resulting in consistently lower bounce rates (under 1% vs Apollo's variable rates). If deliverability matters to your outreach, Mailsfinder is the better choice.

What's the catch with 100K credits for $99? expand_more

No catch. We built efficient infrastructure that lets us offer significantly more value than legacy providers. Credits work for both finding AND verifying emails — one pool covers both actions. We don't charge for "Not Found" results or invalid email addresses either.

Can I switch from my current email finder to Mailsfinder? expand_more

Yes. Upload your existing prospect lists via CSV and start finding verified emails immediately. Most teams switch in under 10 minutes. Mailsfinder also integrates with the same tools you already use — Zapier, Make, n8n, Google Sheets, and REST API — so your existing workflows stay intact.
