Lead List Building

Lead lists your campaign can actually trust

Custom-built, ICP-matched prospect lists — sourced from multiple databases, enriched with firmographics and growth triggers — recent funding, hiring, expansion — and verified so your outreach reaches real decision-makers instead of bouncing.

What's included

Every failed campaign we've audited started with a bad list.

Copy gets the blame; data is usually the culprit. We fix the foundation.

ICP definition

We work with you to define exactly who you sell to: industry, company size, geography, seniority, tech stack and any exclusion criteria.

Multi-source sourcing

Contacts pulled and cross-referenced from multiple B2B databases — no single-source lists, because every database has blind spots.

Enrichment & triggers

Each record enriched with firmographics and, where relevant, growth triggers: recent funding, hiring activity, expansion, technology changes.

Verification you can see

Every email is checked and re-checked before delivery. You receive a clean file showing the verification status of each contact — usable in our campaigns or your own CRM.

Process

From ICP to campaign-ready list

Delivered as a clean, deduplicated file — or piped straight into a LeadSire campaign.

Define the ICP

A short workshop to pin down exactly who we're finding — and who we're excluding.

Source & cross-check

Contacts pulled from multiple databases and deduplicated against each other.

Enrich & segment

Firmographics and growth triggers added; the list segmented for personalised messaging.

Verify & deliver

Every address checked and re-checked, then delivered as CSV/Sheets or loaded straight into your campaign.

Standalone or bundled

Use it with us, or without us

List building is included in every LeadSire campaign — and available on its own.

If you run outreach in-house, we can be your data department: recurring monthly list builds matched to your ICP, verified and ready to load. If you'd rather the whole system was handled, the same lists feed our cold email and LinkedIn outreach campaigns directly — with copywriting that references the growth triggers we enriched.

FAQ

Frequently asked questions

What does a lead list cost?

Pricing depends on volume, targeting difficulty and enrichment depth — quoted per project or as a monthly subscription for in-house teams. Ask for a quotation with your ICP and we'll respond within one business day.

How accurate are the lists?

Every email passes multi-step verification before delivery, which keeps bounce rates in healthy territory. Records that can't be verified are flagged or excluded — we don't pad counts with junk.

Can you find leads in Thailand and Southeast Asia?

Yes — regional data is genuinely harder to source than US/EU data, and it's a specialty of ours. We combine international databases with local sources and manual research where needed.

What format do you deliver in?

CSV or Google Sheets as standard, structured for direct import into any CRM or outreach tool — or loaded directly into your LeadSire campaign.
