Campaign Studio
No time to search? Describe the audience. We build it, verify it live and deliver it.
Write the brief in plain language. Our AI turns it into segments and shows live counts before you pay. Then every record is checked live: mailboxes validated against the receiving mail server, phone numbers dialed by our verification team. Only contacts that pass both checks reach your segmented Excel file with 14 data points each, from name, title and LinkedIn to employee size, company revenue and location, within 4 to 12 hours of payment. Anything that fails never reaches the file or the invoice.

We do not quote a blanket accuracy percentage, because we do something stricter: every email address is tested against the live mailbox in the moment you reveal it. An address the mailbox rejects is never shown and your credit is not spent on it. Addresses that pass are delivered with a green tick: Verified when the exact mailbox confirmed, Accepts mail when the company routes all incoming mail through one accept-all domain.
What exactly is a credit?
One credit reveals one email address or one phone number. Revealing the same contact again later is free. Credits from a monthly pack stay valid for 30 days, and larger packs cost less per credit.
Am I locked into a contract?
No. Plans renew monthly and you can cancel anytime from the Billing page in your account. Annual billing is available if you want it, at 10% off, and top-up packs are one-time purchases.
Is this compliant with GDPR and similar laws?
LeadVault carries business contact data (name, role, employer, work contact details) and follows GDPR, CCPA and CASL aligned practices. Contact details stay masked until a user deliberately reveals them, every reveal is recorded, and removal requests to relations@leadvaultlabs.com are honored.
What if I need a whole list, not a search tool?
That is Campaign Studio. You describe the audience in plain language, we build the list fresh, verify every email while the file is being built, and deliver a segmented Excel file with company revenue and phone numbers included. $11 per verified contact, minimum 100. Anything that fails verification never reaches the file or the invoice.
Can I try it before paying anything?
Yes. A free account takes a minute, needs no card, and comes with 5 credits so you can watch the live verification happen on real contacts. Searching and audience counts stay free forever.
Your next 100 customers are already in here.
Open a free account, run the search your last brief described, and watch the first email verify in front of you. No card, no call, no contract.

Anything that fails is removed or replaced. $11 per verified contact, minimum 100. Self-serve for the United States, United Kingdom and India; larger or other markets are quoted personally.

Live mailbox check
Every email address is checked with the live mailbox verifier the moment someone opens it. An address the verifier rejects is never shown and no credit is spent on it; addresses that pass are delivered with a green mark, Verified for an exact-mailbox pass or Accepts mail for accept-all domains. An answer is kept for 30 days, so opening the same contact again costs nothing.

The upstream network, behind the search
Every search, yours included, runs against the upstream data network: the results, the headline count, the sidebar counts and the home-page figures. Searching costs nothing. Clicking Show spends one network credit for the email, which then goes through the mailbox check; the person is kept so they are never bought twice. The supplier is never named anywhere members can see.

Your plans
Credit packs run on a 30-day validity. A subscribed plan renews
automatically at the end of its period and the pack is granted again; cancel here anytime and it stops
at the period end. One-time purchases simply run out their validity and never renew. The balance from a
period stays usable until that period ends.

Your plan covers your whole team. Add up to 5 licensed teammates: each gets their own

A research account can search the database and uncover contact details one record at a time.
It cannot load data, run verification, see provider keys or manage accounts. Give administrator rights only to people who need them. Contacts they can reach caps how far into the results they can go. Reveal credits are spent one at a time when they
uncover an email or a phone number; uncovering the same one again is free. Leave either blank for no limit.
Card payments
Paste the keys from your Stripe dashboard. They are stored on this server and never shown again.
The webhook endpoint to register in Stripe is .
Or let LeadVault register the webhook with Stripe itself, using the saved key: it creates the endpoint and keeps the signing secret, nothing to copy.
Sending email
New accounts must confirm a work email address before they can search, so this has to work
before you open sign-ups. A cloud server cannot send mail on its own; use a delivery service.
Genie voice and artwork
Genie speaks the count out loud. Paste a voice-service key (ElevenLabs, from elevenlabs.io → Profile → API keys) for a natural US voice; without it the browser's own US English voice is used.
You can also replace the drawn genie with your own illustration: a PNG with a transparent background, portrait, at least 800px tall, looks best.

Data API
Lets a partner's product ask how many people match a brief and show the number to their users, for example
"VP Finance at 500+ staff companies in the United States". The API answers with counts only. It never returns a name, email,
phone, company, LinkedIn URL or any identifier, whatever the key holder asks for. Anyone who wants the people creates a
LeadVault account. Keys can only be created here, by an administrator; a key is shown once at creation. Documentation for
key holders: leadvaultlabs.com/developers.
