The built-in B2B lead database — 200M+ business leads, searchable in-app
WarmySender's built-in lead database gives you 200M+ business leads, searchable right inside the app by role, company, industry, and geography. Searching, filtering, and paging through results is free — a lead only ever costs a credit when you save or export it. Until then, each record stays masked, so you can explore the whole database and build the exact list you want before spending anything, and you only spend credits on the contacts you actually pursue. The lead database is available on Pro plans and up.
The database is built into the same platform you use to reach people, so a saved list flows straight into outreach across all four pillars — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel sequences. Find your ideal prospects, verify their addresses first, and start a campaign — all from one dashboard, starting at $14.99/month.
What it is
The lead database is a large, searchable pool of business contacts you can use to build targeted prospect lists without leaving WarmySender. Each lead comes with the details you need to reach a real person: name, job title, company, work email, and (where available) a LinkedIn profile. You filter the pool down to exactly the people who fit your offer, save them to a list, and move them into a campaign.

How to use it — filter, save, export
- Filter. Open the Leads page and stack filters — role or job title, company, industry, and geography — until the live match count shows only the people you want to reach. The filters are additive, so each one you add narrows the list further.
- Save. When the results look right, save the leads you want to a list. Saving reveals the full record (until then each email shows masked) and spends one credit per new lead. Re-saving a lead you already saved is free — you're never charged twice for the same contact.
- Export. Take your saved list straight into a campaign, or export it as a CSV to use however you like. Records with no email aren't charged.

How it feeds your outreach
Because the database lives in the same platform as your campaigns, there's no exporting and re-importing between tools. Once you've saved a list, you can:
- Push leads straight into cold email campaigns — build a multi-step sequence and enroll your saved list in a few clicks.
- Add them to LinkedIn outreach — for leads with a LinkedIn profile, run connection requests and follow-up messages at a safe, natural pace.
- Combine both in a multichannel sequence — mix email and LinkedIn steps so you reach each person on the channel where they're most likely to reply.
Before you send, verify the addresses first with the built-in email verifier. Verifying protects your sender reputation and keeps bounce rates low, so the mailboxes you've warmed up keep landing in the inbox.
Lead credits
Every paid plan (Pro and up) includes access to the lead database. When you need to save more leads than your plan covers, you can top up with one-time lead credits:
- Credits never expire. A one-time pack stays on your account until you use it — there's no monthly reset and nothing to lose if you don't use it all this month.
- One credit per new lead. A credit is spent only when you save a new lead to a list or export it. Re-saving a lead you already have is free, and records with no email aren't charged.
- Browsing stays free. Searching, filtering, and paging through results never touch your credits — you only spend when you commit to a contact.

What WarmySender covers
The lead database is one part of an all-in-one outreach platform built on four pillars — and every lead you save can flow into all of them:
- Cold emailing — multi-step campaigns with personalization that land in the inbox.
- Email warmup — build and protect sender reputation so your emails don't go to spam.
- LinkedIn outreach — automate connection requests, messages, and follow-ups safely.
- Multichannel — combine email and LinkedIn steps in one sequence, with every reply in a single inbox.
Frequently asked questions
How many leads are in the database?
The built-in lead database contains 200M+ business leads. You can search the whole pool by role or job title, company, industry, and geography, and narrow it down with additive filters until the live match count shows only the people who fit your offer.
Is searching the leads free?
Yes. Searching, filtering, and paging through results is completely free and never spends credits. Each record stays masked while you explore, and a credit is only spent when you save a lead to a list or export it — so you can build the exact list you want before committing to any contact.
What data comes with each lead?
Each lead includes the details you need to reach a real person: name, job title, company, and work email, plus a LinkedIn profile where one is available. Leads with a LinkedIn profile are ideal for multichannel outreach that combines email and LinkedIn.
How do lead credits work?
Every paid plan includes access to the database, and you can top up with one-time lead credits when you want to save more. Credits never expire, one credit is spent per new lead you save or export, re-saving a lead you already have is free, and records with no email aren't charged. Browsing always stays free.
What happens when I save or export a lead?
Saving a lead reveals its full record (the email is masked in search until then) and adds it to a list you can enroll in a campaign. Exporting hands you the list as a CSV. Either action spends one credit per new lead; re-saving or re-exporting a lead you already have doesn't cost anything extra.
Can an AI agent search the database for me?
Yes. WarmySender offers a public REST API and an MCP server, so an AI agent (such as Claude or ChatGPT) can search the lead database, save leads, and even build and launch campaigns on your behalf in plain language — the same actions you'd take in the app, driven by your assistant.
