Open a LinkedIn profile, click once, get the person's work email — and an honest label saying how sure we are. You pay only for addresses we can prove. Guesses are free, and marked as guesses.
A mail server that accepts every address cannot confirm any of them. Most lead tools bill you for those anyway. LeadProve tells you which is which, and only charges for the ones that hold up.
An address is billed only when a mail server, a published source, or a clean delivery confirms it. Anything else is shown, labelled unproven, and costs nothing.
If a proven address hard-bounces, the credit comes back automatically and the address is demoted for everyone. No ticket, no argument.
Many large staffing companies sit behind mail gateways nobody can verify against. We say so instead of selling you a pattern guess as fact.
A contact you already bought is free forever on your account — find them again next quarter and nothing moves. A miss costs nothing either.
LinkedIn → email → phone → CSV. Company names resolve the way staffing firms actually name themselves. Mark leads sent, replied, placed.
The extension reads the profile you have open, when you click. It never changes the page, never runs in the background, never visits profiles for you, and paces your lookups like a person.
Create a free account, copy the API key from your dashboard, paste it into the extension once.
LeadProve reads the name and employer already on your screen, works out the company's real domain, and finds the address.
Proven means we can stand behind it and you were charged one credit. Unproven means it is our best guess at a mail server that will not tell anyone — free, use your judgement. Tell us Delivered or Bounced afterwards and the whole system gets smarter.
