List Broker Reviews — 2026

How this market actually works

The market splits into two economic models. Data platforms (ZoomInfo, Apollo, Cognism) sell continuous access: filters, integrations, refreshed records — priced as annual subscriptions that make sense for teams prospecting every day. List sellers (brokers and one-time catalogs) sell a file: you pay once, own the export, and owe nothing next month — which is the rational choice for defined campaigns, market tests, and any team without a daily outbound motion. Neither is universally better; the mistake is paying platform prices for a one-campaign job, or expecting a static file to behave like a live database. Enterprise sales-intelligence subscriptions typically run from roughly $5,000 to $15,000+ per year, while static list brokers sell one-time datasets from under $100.

Before you buy from any of them

Whichever vendor you shortlist, the same seven checks separate usable files from expensive bounces:

1. Sample first. Any legitimate seller will provide 25–50 sample records for your exact segment. Refusal is disqualifying.
2. Verify the sample. Run it through a verification tool. A sample returning more than ~5% invalid addresses predicts a file you'll regret.
3. Ask the refresh date. When was this file last validated? A specific answer ("re-verified in the last 90 days") beats a vague one ("continuously updated").
4. Check field completeness. A contact record without company, title, and a person-level (not info@) address is worth a fraction of a complete one.
5. Confirm sourcing. Compiled from public/business registries, opt-in programs, or scraped? The answer determines both quality and your legal exposure.
6. Get the price in writing per record, including every "select" surcharge, before committing.
7. Review the replacement policy. Reputable sellers replace or credit hard bounces above a stated threshold.
