How to pick one
- Do you want a tool or a list? ZoomInfo, Apollo and Lusha are tools: you pay for seats and search yourself. A list provider hands you the file. If nobody on your team has time to build lists, a tool sits unused.
- Where are your buyers? Most providers are strongest in the US. For the UK and Europe, Cognism is the usual reference for mobile numbers.
- What does a bounce cost you? Bounces hurt your sender reputation. Independent user tests posted in 2026 found some popular databases bouncing above 30%. Ask every provider for a sample and verify it before you pay.
- Do you need phone numbers? Ask for them by name. Mobiles cost more everywhere.

Questions people ask
What is the best B2B leads provider?
It depends on what you need. ZoomInfo for large US teams, Cognism for Europe, Apollo.io for a low-cost tool, Lusha for single lookups, and PromptLeadz for a checked list built to your brief without a subscription.
What is the cheapest way to get B2B leads?
For a handful of contacts, the free plans from Apollo.io and Lusha. For volume without a subscription, a one-off list: PromptLeadz starts at $29 for 1,000 leads and drops to 0.8c a lead at 100,000.
How do I check lead quality before buying?
Ask for real sample rows from your exact target, run them through an email checker, then send a small batch first and watch the bounce rate. A good list keeps bounces low enough that your sending domain stays healthy.
Is buying B2B leads legal?
Contacting people at work about relevant business offers is allowed in many countries, but the rules differ. GDPR applies in the UK and EU, CAN-SPAM in the US. Check the rules where you and the people you email are based.
Can I get mobile numbers too?
Yes, from most providers at a higher price. At PromptLeadz, mobiles are added at double the tier price, from 9 million contacts with a mobile number.
