B2B lead generation tools mostly pull from the same handful of underlying data sources, resold and enriched differently — so contact accuracy varies less between tools than the marketing suggests, and varies more by region (US data is consistently better than European) than by which logo is on the tool.
Pick based on what you actually need: a database to search and export from, an enrichment layer to add to existing contacts, or a fuller platform that also handles outreach. Below is what each is genuinely good at.
How we judged them
What matters when you're small.
Data accuracy by region
US contact and email data is generally more reliable across every provider than European or APAC data. If you're selling outside the US, test a sample export before committing to a plan.
Credit-based pricing vs flat monthly
Many tools charge per credit (roughly per contact revealed or verified), which can get expensive fast if you're doing broad list-building rather than targeted outreach.
Enrichment and waterfall verification
The best tools cross-check multiple data sources ('waterfall') rather than relying on one, which meaningfully reduces bounce rates on the emails you get.
Compliance with GDPR for European contacts
If you're prospecting into the EU or UK, check the tool's stated compliance approach — some providers are noticeably more careful about this than others.
The picks
What each one is actually good at.
Apollo
Free tier, paid from about $49 a user a monthBest for: Startups wanting a database plus sending in one place
Best value all-rounder — searchable database, enrichment and basic sequencing together. US data is solid; European data is noticeably patchier, so verify before a big send.
Clay
Free tier, paid from about $149 a monthBest for: Building enriched, waterfalled lists from multiple sources
Not a database itself — it pulls from dozens of providers and lets you build custom enrichment logic, which produces meaningfully better data than any single source alone. Takes a week or two to learn properly.
ZoomInfo
Custom pricing, typically starts in the low five figures annuallyBest for: Larger teams needing the deepest, most accurate US data
The most accurate and comprehensive US contact data available, with strong intent data layered on. Priced and contracted for mid-market and enterprise teams, not early-stage startups.
Lusha
Free limited credits, paid from about $29 a month per userBest for: Quick one-off contact lookups via browser extension
Fast for grabbing a single contact's details while browsing LinkedIn. Less useful for building large targeted lists compared with Apollo or Clay, which are built for that specifically.
Cognism
Custom pricing, quote-basedBest for: B2B teams prospecting heavily into Europe
Noticeably stronger European and UK phone and email data than most US-centric competitors, plus a clear GDPR compliance story. No self-serve pricing, so expect a sales call before you know the real cost.
LinkedIn Sales Navigator
From about $99.99 a monthBest for: Manual, targeted prospecting rather than bulk list-building
The best filtering for finding the right person by role and company signals, but it doesn't hand you a verified email — pair it with an enrichment tool to actually get contact details.
Skip
What we'd leave alone.
- Any provider quoting near-100% email accuracy — even the best waterfall tools land around 90–95% deliverable on a good day.
- Bought or scraped 'lifetime access' contact databases — the data ages within months and using it risks your sending domain's reputation.
- Enterprise-only tools (ZoomInfo, Cognism) before you have a dedicated SDR or clear ICP — the annual contract commitment doesn't suit early-stage experimentation.
Questions
Common questions.
How accurate is B2B contact data really?
Expect 85–95% deliverability from a good provider on US contacts after verification, lower for European contacts. Always run a separate bounce-check before a large send regardless of the source.
What does 'waterfall enrichment' mean?
Checking a contact against multiple data providers in sequence and taking the first verified match, rather than relying on a single source. It's the main reason Clay-style setups outperform a single database lookup.
Is Apollo's free tier actually usable?
Yes for light use — enough to test the data quality and run a small campaign before deciding whether to pay. Credit limits reset monthly and are fairly generous for occasional use.
Do I need ZoomInfo if I'm an early-stage startup?
Almost never. It's built for teams with dedicated SDRs running high-volume outbound with a real budget for it — Apollo or Clay covers the same underlying need at a fraction of the cost early on.
Is it legal to buy or scrape B2B contact data for cold outreach?
Generally yes for B2B in most jurisdictions under legitimate interest, but GDPR still requires proper handling and an easy opt-out — check the specific rules for the countries you're targeting, especially in the EU and UK.
