Open a LinkedIn profile, click once, get the person's work email — and an honest label saying how sure we are. Every address is labelled verified or likely, with the evidence. Weak guesses are free, and a bounce refunds its credit.
A mail server that accepts every address cannot confirm any of them. Most lead tools hand you those as "verified" anyway. LeadProve tells you which is which — verified, or likely with the share of the company's real addresses that follow the same pattern.
Verified: a mail server, our data provider, a published source or a clean delivery confirmed it. Likely: nobody can confirm it, but it follows the company's naming pattern for most of its real addresses — we show the match rate. Both cost one credit. Weaker guesses are shown and free.
If an address you paid for 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.
Verified means it was confirmed. Likely means the mailbox cannot be confirmed by anyone, but it matches how the company names its people, with the match rate shown. Both are one credit. Unverified · free is a weaker guess — use your judgement. Tell us Delivered or Bounced afterwards; a bounce refunds the credit.
