Our take
Hunter is one of the established names in finding and verifying business email addresses, and verification is the half that actually protects you — a bounce rate above a couple of percent damages your sending domain in ways that take months to repair. Pricing is at the higher end. The legal dimension is yours to handle regardless of what the tool provides.
Worth it if
Teams doing outbound at volume who need verification accuracy more than the lowest per-credit price.
Look elsewhere if
Anyone mailing EU or Canadian recipients without having worked out their lawful basis first.
✨ Features
Domain Search
Find the email addresses associated with any company domain.
Email Finder
Retrieve a verified email address from a person's name and company.
Email Verifier
Validate addresses to reduce bounces and protect sender reputation.
Yes, and it is the part most people under-value. Mailbox providers read bounces as evidence of a purchased list, and the damage falls on your domain rather than the campaign. Verifying immediately before sending, rather than when the list was built, matters too — business addresses decay by roughly a quarter a year.
Am I allowed to email addresses I find this way?
It depends where the recipient is. GDPR requires a lawful basis and a documented balancing test for B2B email in the EU, Canada's CASL requires consent or a documented existing relationship, and the US is more permissive under CAN-SPAM. The tool supplying the address is not a defence in any of those regimes.
