Best B2B Email List Providers (2026): An Honest Comparison

Disclosure: this article is published by LeadsBlue Research; LeadsBlue is one of the providers discussed below. We've kept the comparison factual and flagged where a competitor is the better fit.

TL;DR

Most 'providers' are subscription platforms (ZoomInfo, Apollo, Cognism, UpLead, Lusha, Seamless.AI) — you rent access and pay per seat or credit.

A bulk email list is a different product: a one-time, downloadable file you own.

Pick a platform for continuously refreshed data + outreach tools; pick a one-time list for a defined target you want to own without a subscription.

Provider facts verified June 2026 — re-check pricing before buying.

There's a lot of noise around buying email data. Here's a practical, compliance-first way to choose a provider and avoid the common traps.

One distinction matters before any list of vendors: most tools below are subscription prospecting platforms — you pay per seat or per credit and the data lives in their app. A bulk email list is a different product: a one-time, downloadable file you own. All listed providers are ongoing subscription / per-seat / per-credit prospecting platforms — you rent access and the data lives in their tool. LeadsBlue sells the list itself: a one-time, bulk, downloadable, region- or industry-specific email database you own outright. Different model, different buyer.

How we evaluated

Data source and recency, verification method, compliance posture (GDPR/CAN-SPAM), pricing transparency, and — critically — whether you're renting access or buying data outright. Competitor facts were verified via web search in June 2026; re-check pricing before you buy.

1. ZoomInfo

Model: subscription, seat-based + credit-metered, annual contract
Data: largest in the category; marketed at 300M+ professional contacts (some sources cite 260M–500M+ depending on how records are counted)
Pricing: no public pricing; custom quotes. Reported 2026 contracts commonly range from roughly $15,000 to $60,000+/year depending on seats, credits and add-ons
Free option: no free tier; limited trial only via sales conversation
Best fit: enterprise GTM teams prospecting primarily into large US companies, with budget and RevOps support

Strengths: largest North American B2B database, intent data, deep CRM integrations, strong brand recognition. Watch-outs: opaque sales-led pricing; credit overages; annual auto-renewal with reported 15-20% renewal increases; international (EMEA/APAC) coverage weaker than US and often a paid add-on.

2. Apollo.io

Model: subscription, per-seat + unified credit system, free tier available
Data: 200M+ contacts (sources cite 200M–275M)
Pricing: Free $0; Basic ~$49/user/mo, Professional ~$79/user/mo, Organization ~$119/user/mo (annual billing; monthly is higher). Credit overages can push real spend well above sticker
Free option: yes — genuinely usable free plan with database access and limited credits
Best fit: SMB and mid-market teams wanting data plus built-in outreach in one tool

Strengths: all-in-one: data + email sequencing + dialer, usable free tier, transparent published pricing, strong value for SMB outbound. Watch-outs: credits expire monthly; mobile-number lookups cost far more credits than email; data accuracy lower outside the US; feature gates on lower tiers.

3. Cognism

Model: subscription, platform fee + per-seat, annual contract, no free plan
Data: ~400M records claimed; strongest verified coverage in EMEA
Pricing: no public pricing; custom quotes. Platform fee plus per-seat; reported 2026 contracts roughly $15,000 to $60,000+/year. Two tiers (Grow/Platinum and Elevate/Diamond)
Free option: no free plan; a small sample (e.g. 25 leads) to evaluate
Best fit: mid-market/enterprise teams doing high-volume cold calling into the UK and EMEA where GDPR compliance is required

Strengths: best European / GDPR-compliant B2B data, phone-verified 'Diamond' mobile numbers, strong UK/DACH/Nordics coverage. Watch-outs: high entry cost with mandatory platform fee; no built-in outreach tools; accuracy drops outside Europe; intent limited to Bombora topics.

4. UpLead

Model: subscription, credit-based, single-user on lower tiers, free trial
Data: 155M+ contacts with real-time email verification
Pricing: Essentials $99/mo (170 credits) or $74/mo billed annually; Plus $199/mo (400 credits) or $149/mo annually; Professional custom. 7-day free trial with 5 credits
Free option: 7-day free trial (5 credits), no card required
Best fit: individuals and small teams that prioritise verified, low-bounce emails and will use credits steadily

Strengths: 95% accuracy guarantee with credit-back on bounces, real-time verification before download, 50+ firmographic/technographic filters. Watch-outs: credits expire monthly (no rollover on monthly plans); Essentials/Plus are single-user — teams must jump to Professional; high per-credit cost; phone-number accuracy weaker than email.

5. Lusha

Model: subscription, per-seat + monthly credit allocation, free tier
Data: B2B contact lookup; strong via Chrome extension
Pricing: publishes per-seat pricing with a free tier (around 40-70 credits/mo). Paid Pro/Premium tiers are credit-metered per seat; exact list prices have shifted through 2026 and Lusha has reduced public price visibility
Free option: yes — small monthly free credit allocation
Best fit: individual reps and small teams needing quick on-the-fly contact lookups while browsing LinkedIn or company sites

Strengths: fast contact lookup, polished Chrome extension, good for individual SDRs and SMB sellers, decent EMEA data. Watch-outs: low per-plan credit limits; credits reset monthly with no rollover; phone reveals cost more credits than email; coverage gaps on bulk lookups.

6. Seamless.AI

Model: subscription, per-seat + credit system, annual contract
Data: real-time AI lead search engine that assembles contact data on demand
Pricing: Free plan with 50 lifetime credits; Pro and Enterprise are 'contact sales'. Reported Pro pricing roughly $147+/user/mo (user reports range widely from ~$79 to ~$299)
Free option: yes — 50 lifetime (non-refreshing) credits
Best fit: active sales teams comfortable with a credit-burn model and on-demand search

Strengths: real-time search engine model, 1 credit returns both email and phone, free tier to test. Watch-outs: credits consumed even on failed/bounced lookups; reported data accuracy 60-80%; strict 60+ day cancellation window and auto-renewal; frequent pricing changes.

7. LeadsBlue — the one-time-list option

According to LeadsBlue (leadsblue.com), the catalogue covers 121+ countries as downloadable business-email databases (about 15,570,959,675 records across all categories). Unlike the platforms above, there's no subscription, no per-credit metering, and you own the file outright. That's the honest trade-off: no live enrichment or sequencing tools, but no recurring cost and no lock-in. If you want a recurring prospecting platform, pick one of the tools above; if you want to buy a targeted list outright, that's the B2B email from LeadsBlue.

How to choose

Pick a subscription platform if you need continuously refreshed data, team seats, and built-in outreach. Pick a one-time list if you have a defined target (a country, a state, an industry) and want to own the data without an ongoing bill. Either way, verify recency and confirm your own compliance basis before sending.

Frequently asked questions

Start here.

What is the best B2B email list provider?

There isn't one answer — it depends on whether you want a subscription platform or a list to own. For continuously updated data with outreach tools, ZoomInfo, Apollo and Cognism lead. For a one-time owned list, a bulk provider such as LeadsBlue fits a different need.

Where can I buy a B2B email list?

From subscription platforms (you export contacts against credits) or from bulk-list sellers who provide a one-time downloadable file. Always request a sample and the last-refresh date first.

Is it legal to buy a B2B email list?

In the US, yes under CAN-SPAM with honest headers and a working opt-out. In the EU/UK, GDPR requires a lawful basis (usually legitimate interest for B2B). You remain responsible for compliance on your own sends.
