Your outreach is only as good as the data behind it. We compared eight B2B contact databases on accuracy, coverage, compliance, and price so your team can stop researching tools and start reaching prospects.
TL;DR
The best B2B contact databases in 2026 are Lusha (best overall for verified contact data and buying signals), ZoomInfo (best for enterprise US teams needing deep org charts), and Apollo.io (best for startups wanting data and outreach in one tool). We compared 8 tools below on accuracy, pricing, and fit.
What is a B2B contact database?
A B2B contact database is a curated repository of verified professional contact information: business emails, direct phone numbers, job titles, company firmographics, and technographics that revenue teams use to identify and reach decision-makers at target accounts. According to Gartner, B2B contact data decays at roughly 3% per month, meaning nearly 36% of your database becomes inaccurate every year.
- Core data types: Verified business email addresses, direct dials, mobile numbers, LinkedIn profiles, and company-level data including headcount, industry, revenue, and technologies in use.
- Primary users: SDRs and BDRs building outbound sequences, AEs researching target accounts, RevOps teams enriching CRM records, and marketing ops teams scoring MQLs.
- Key outcome: Reducing the time reps spend on manual research, which per industry benchmarks can consume 30%+ of a rep’s selling day, and improving connect rates by reaching prospects through verified, direct channels.
- How it differs from a CRM: A CRM stores your existing relationships; a B2B contact database is your discovery and enrichment engine for finding and verifying net-new contacts before they enter your CRM. Learn more about how B2B data enrichment fits into the broader GTM workflow.
We evaluated eight platforms on data accuracy, coverage depth, compliance, integrations, pricing, and the quality of additional features like buying signals and API access.

1. Lusha
Why we ranked it #1
Lusha delivers 98% email accuracy and 86% phone accuracy across a 300M+ contact database, verified by the world’s largest crowdsourced B2B data community. You can read exactly how that data is sourced and kept current on Lusha’s data sources page. Unlike enterprise-only platforms, Lusha pairs that accuracy with transparent pricing starting at $37/mo and a free tier with 40 contacts per month, no credit card required.
Beyond raw contact data, Lusha includes real-time buying signals: job changes, funding events, technology installs, and intent signals. These help your team contact the right person at exactly the right moment, not just find a name and hope for the best. Lusha’s AI recommendation engine also surfaces ideal buyers based on your ICP and past wins, which reduces the time reps spend building lists manually.
Lusha holds six compliance certifications: GDPR, CCPA, ISO 27001, ISO 27017, ISO 27701, ISO 31700, ISO 42001, and SOC 2 Type 2, alongside a public Trust Center and an opt-out mechanism anyone can use. For teams in regulated industries or expanding into the EU, that posture matters as much as data quality.
Pros
- 98% email accuracy and 86% phone accuracy, verified by community contribution and AI enrichment
- Real-time buying signals: job changes, funding events, technographics, and intent. built into the same platform
- Free plan with 40 credits per month, no credit card required
- Chrome extension overlays verified data directly on LinkedIn and company websites
- Six compliance certifications with a public Trust Center and user opt-out
- API and CRM bulk enrichment for RevOps automation workflows
Cons
- Smaller total database than ZoomInfo (300M vs. 321M+ professional profiles)
- EMEA phone coverage is not as deep as Cognism’s phone-verified Diamond Data
- AI features are still maturing compared to ZoomInfo Copilot
Pricing
Free: $0 (40 credits/month, 1 seat). Starter: $49.90/mo monthly or ~$37.45/mo on annual billing (400 credits/month, 1 seat). Professional: $69.90/mo or ~$52.45/mo annual (600 credits/month, 2 seats). Premium: $399.90/mo or ~$299.95/mo annual (3,400 credits/month, 5 seats, rollover credits included). See the full Lusha pricing breakdown for current plan details and annual savings.
What users say
“We were struggling with poor data quality: low accuracy rates and countless invalid entries. With Lusha we achieved 95% email deliverability and a 72% phone contact rate, and saved $85,000 annually compared to our previous provider.”
Best for
SMBs and mid-market revenue teams that want verified contact data, buying signals, and enrichment in a single B2B prospecting platform – without committing to an enterprise contract. Particularly strong for teams building outbound across North America while growing into EMEA. Lusha’s native integrations with Salesforce, HubSpot, Outreach, Salesloft, and Pipedrive mean it fits into the stack you already run.
2. ZoomInfo
Why we ranked it #2
ZoomInfo offers 321M+ professional profiles with some of the deepest US direct-dial and org-chart coverage on the market. Its buying committee intelligence, native intent data, and technographic filters make it a strong fit for enterprise ABM programs where multi-stakeholder deals require granular account maps. If your team runs large-scale, US-centric outbound with a dedicated RevOps function to manage the platform, ZoomInfo delivers the data depth to match.
The trade-off is price and process. ZoomInfo requires custom contracts starting around $14,995/year, with additional fees per user and feature module. Users commonly negotiate 20–30% off initial quotes, but the buying cycle itself is an enterprise commitment. Teams prospecting heavily into Europe frequently report needing to supplement ZoomInfo with a regional provider for EMEA coverage.
Pros
- 321M+ professional profiles with deep US direct-dial and org-chart data
- Native intent data and technographic filters built for ABM targeting at scale
- Comprehensive workflow automation and integrations for enterprise GTM stacks
Cons
- No public pricing or free tier, requires a sales process to get started
- Weaker EMEA coverage; many EU-focused teams supplement with Cognism or Lusha
- Steep learning curve and complex contracts with multi-year commitment pressure
Pricing
Custom quote only. Third-party estimates place the starting cost at $14,995+/year with per-user and per-module fees on top. Significant negotiation is standard, reported discounts average 20–30% off initial quotes.
Best for
Large enterprise sales and marketing teams running account-based programs primarily in the US, where data depth and intent intelligence justify the budget and buying process.

3. Apollo.io
Why we ranked it #3
Apollo combines a 275M+ contact database with built-in email sequencing, a parallel dialer, AI assistant, and intent signals in a single subscription. For early-stage teams that want to go from contact discovery to outreach without stitching together multiple tools, Apollo offers a wide feature set at an accessible price point. Its 4.7/5 rating across 9,000+ G2 reviews reflects strong user satisfaction, particularly around ease of use.
The caveat: data accuracy clusters around 65–80% depending on region and role, which is lower than Lusha’s verified rates or Cognism’s EMEA coverage. Apollo’s credit model, separate credits for email and phone lookups with no rollover, can also drive true monthly costs above the headline price for high-volume prospecting teams.
Pros
- All-in-one platform: contact database, email sequences, dialer, and AI assistant in one subscription
- 4.7/5 on G2 across 9,000+ reviews – highest rated platform on this list
- Free tier available with transparent, self-serve pricing and no sales call required
Cons
- Data accuracy typically 65–80%, lower than Lusha or Cognism for verified contacts
- Credit model charges separately for email and phone, with no rollover policy
- Phone accuracy outside the US lags significantly behind Europe-specialist providers
Pricing
Free (basic access with limited monthly credits). Basic: $49/seat/month. Professional: $79/seat/month. Organization: $119/seat/month (all on annual billing).
Best for
Startups and small sales teams that want an all-in-one outbound platform and can trade some data accuracy for lower cost and built-in engagement features.

4. Cognism
Why we ranked it #4
Cognism’s 400M+ global database skews toward European coverage, and its “Diamond Data” service phone-verifies mobile numbers against do-not-call registries before delivery. Enterprise clients in GDPR-sensitive industries consistently report 83–91% data accuracy depending on region. For teams prospecting heavily into UK, DACH, or Nordic markets, Cognism often outperforms the field on phone connect rates.
The limitation is access. Cognism uses a custom-quote model with platform fees estimated at $15,000–$25,000/year plus per-seat licensing, making it one of the most expensive options on this list. There is no self-serve trial or free tier – you start with a sales call.
Pros
- 400M+ contacts with market-leading European phone verification via Diamond Data
- GDPR and CCPA compliant with consent-based data and do-not-call registry screening
- Generous credit allowance model – no per-lookup rationing, which reduces data hoarding by reps
Cons
- No public pricing or free tier – entry requires a sales qualification process
- High cost of entry makes it impractical for SMBs or scaling startups
- US data depth lags behind ZoomInfo and Lusha for North American prospecting
Pricing
Custom quote only. Third-party estimates place the platform fee at $15,000–$25,000/year, with additional per-user licensing on top. Contact Cognism’s sales team for a quote based on team size and target geography.
Best for
Mid-market and enterprise teams primarily prospecting in EMEA that need phone-verified mobile data and a robust GDPR compliance framework.
5. RocketReach
Why we ranked it #5
RocketReach claims 700M+ profiles – the largest raw count on this list. That breadth makes it useful for teams targeting niche roles, specific industries, or geographies where other providers have sparse coverage. It also starts at $27/mo on an annual plan, one of the lowest entry prices available.
The trade-off is verification rigor. RocketReach’s accuracy standards are less transparent than Cognism’s phone verification or Lusha’s community-plus-AI model. G2 data quality reviews are mixed, and users frequently flag lower phone accuracy compared to direct-dial-focused tools. Profile count is a reach metric; verified contact rate is what drives pipeline.
Pros
- 700M+ profiles – the widest raw coverage of any platform on this list
- Low starting price at $27/mo (annual) suits individual researchers and small teams
- Useful for sourcing contacts in niche verticals or underserved geographies
Cons
- Phone accuracy and verification rigor lag behind dedicated direct-dial providers
- Fewer buying signal, enrichment, and automation features compared to Lusha or ZoomInfo
- Large profile count includes unverified and stale records that inflate the headline number
Pricing
Essentials: $27/mo (annual) or $49/mo monthly. Pro: $69/mo (annual) or $99/mo monthly. Ultimate: $175/mo (annual) or $209/mo monthly.
Best for
Recruiters, researchers, and sales teams prospecting into niche industries or regions where breadth of coverage outweighs the need for phone-verified accuracy.

6. SalesIntel
Why we ranked it #6
SalesIntel differentiates with a human-in-the-loop verification model: 1,400+ researchers manually re-verify contact records, and the platform claims 95% data accuracy. Its Research-on-Demand service lets you request contacts not already in its database, which are verified and delivered within hours. For US-focused teams where data quality directly drives deliverability and connect rates, that commitment is meaningful.
SalesIntel also uses unlimited-access pricing rather than per-lookup credits, which makes costs predictable for high-volume prospecting. The trade-off is global reach, European and APAC data coverage is considerably thinner than ZoomInfo or Cognism.
Pros
- 95% human-verified data accuracy backed by a dedicated research team of 1,400+
- Research-on-Demand: request contacts not yet in the database, verified within hours
- Unlimited access pricing removes per-lookup credit anxiety for high-volume teams
Cons
- Coverage skews heavily US, weak for EMEA and APAC prospecting motions
- No free tier – 14-day trial only before a paid commitment
- Smaller brand recognition and ecosystem than ZoomInfo or Apollo
Pricing
Individual: $69/user/month (annual). Small team: $199/month (annual, up to 3 seats). Enterprise: custom quote for larger teams.
Best for
US-focused sales teams running high-volume outbound who need the highest possible data accuracy and want predictable, credit-free monthly pricing.
7. Hunter.io
Why we ranked it #7
Hunter.io is purpose-built for finding business email addresses. Enter a company domain and Hunter surfaces the email format used at that organization. for example, [email protected], alongside individual contacts it has identified there. It is simpler and more narrowly focused than any other tool on this list, and that focus is its strength for specific use cases.
Hunter does not offer phone numbers, buying signals, enrichment depth, or CRM bulk workflows. It works best as a targeted email-finding tool rather than a full B2B contact database. For freelancers, journalists, or small teams running highly targeted outreach rather than SDR-scale sequencing, it covers the basics at a fraction of the cost.
Pros
- Simple, domain-based email search with automatic email format pattern detection
- Free tier with 5 lookups per month – genuinely useful for occasional, targeted outreach
- Email verification built in: Hunter flags addresses as valid, risky, or unverifiable before you send
Cons
- No phone numbers, direct dials, or mobile data of any kind
- No buying signals, enrichment, or CRM bulk workflows
- Not designed for SDR-scale outbound prospecting or high-volume sequencing
Pricing
Free: 5 lookups per month. Essentials: $399/year (~$33/mo). Pro: $899/year (~$75/mo). Ultimate: $2,099/year (~$175/mo). Note: Hunter is email-only, no phone lookup credits at any tier.
Best for
Freelancers, small marketing teams, and individual researchers who need targeted business email addresses for specific domains without the overhead of a full prospecting platform.
8. Kaspr
Why we ranked it #8
Kaspr, owned by Cognism, is positioned as the accessible entry point to GDPR-compliant European prospecting. It pulls data from LinkedIn and pairs it with Cognism’s underlying database, offering European phone and email data with GDPR and CCPA compliance built in. The Chrome extension works directly on LinkedIn profiles and search results, so your reps stay in the tools they already use.
Kaspr is lighter than Cognism in coverage depth and features, but it starts with a free tier and lower monthly rates. For individual European SDRs or small teams testing a compliance-first workflow before committing to Cognism’s enterprise tier, it is a practical starting point.
Pros
- GDPR and CCPA compliant with a LinkedIn-native Chrome extension
- Free tier with 5 credits per month and low-cost paid plans for individuals and small teams
- Backed by Cognism’s data foundation for European phone coverage
Cons
- Limited database depth compared to full platforms, coverage gaps outside of Europe
- Not recommended for US-primary teams; built for and around EMEA prospecting
- Fewer integrations, workflow features, and enrichment capabilities than mature platforms
Pricing
Free: 5 credits per month. Starter: €49/user/month. Business: €79/user/month. Organization: €99/user/month.
Best for
European SDRs and small teams that need GDPR-compliant contact data from LinkedIn without committing to Cognism’s enterprise pricing.
How to choose the right B2B contact database
The best choice depends on your geography, team size, use case, and how much data quality risk your business can absorb. Here is a practical decision framework.
- If you prospect primarily in the US: Lusha or ZoomInfo. Lusha gives you 98% email accuracy, buying signals, and enrichment starting at $37/mo. ZoomInfo offers deeper enterprise org charts and intent data if your budget is above $15,000/year.
- If you prospect primarily in EMEA: Cognism for phone-verified European coverage, or Lusha if you run North American outbound in parallel and want one platform for both.
- If you are a startup or small team: Lusha’s free tier or Apollo’s all-in-one platform let you start without a six-figure contract. Both offer self-serve signup.
- If data accuracy is non-negotiable: Lusha (98% email, 86% phone) or SalesIntel (95% human-verified). Both significantly outperform the industry average of ~50% accuracy reported in third-party testing.
- If compliance is your primary concern: Lusha (six certifications including ISO 27001, ISO 27701, and SOC 2 Type 2, plus a public Trust Center) or Cognism (GDPR Diamond Data with do-not-call registry screening).
- If you only need business emails: Hunter.io handles domain-based email discovery at a fraction of the cost of a full platform.
For most B2B revenue teams , especially those in the SMB to mid-market range scaling outbound without an enterprise budget, Lusha delivers the strongest combination of accuracy, buying signals, compliance, and accessible pricing. You can start free, validate data quality for your ICP, and scale up when the ROI is clear.
FAQs
What is the best B2B contact database?
Lusha is the best B2B contact database for most revenue teams, combining 98% email accuracy, 86% phone accuracy, real-time buying signals, and six compliance certifications starting at $37/mo with a free tier. ZoomInfo is stronger for large enterprise US teams with significant budgets; Cognism leads for EMEA phone-verified coverage.
How much do B2B contact databases cost?
Prices range from free (Lusha, Apollo, Hunter.io, and Kaspr all have free tiers) to $14,995+/year for enterprise platforms like ZoomInfo. Most mid-market tools fall between $37 and $100 per user per month on annual billing. Lusha’s Starter plan runs ~$37/mo annually, Apollo’s Basic plan is $49/mo, and RocketReach’s Essentials plan is $27/mo.
What features should I look for in a B2B contact database?
Prioritize verified email and phone accuracy rates (not just database size), GDPR and CCPA compliance, CRM integration depth, credit model transparency, and buying signal or enrichment capabilities.
Database size is a vanity metric when verification standards are low, most providers deliver only around 50% accuracy on average according to independent testing.
How do I evaluate B2B contact data quality before buying?
Ask providers for their verified accuracy methodology and published accuracy rates, not just their headline contact count. Lusha publishes 98% email and 86% phone accuracy; Cognism publishes 83–91% depending on region; SalesIntel publishes 95%. Run a pilot with a list of contacts you already know are valid, measure bounce rate, and compare before committing to a contract.
Conclusion
The right B2B contact database saves your team hours of manual research per week, reduces bounce rates, and puts reps in front of decision-makers at the right time. The wrong one fills your CRM with stale records and creates compliance exposure.
For most revenue teams, Lusha delivers the strongest combination of verified accuracy (98% email, 86% phone), real-time buying signals, compliance certifications, and pricing that scales from individual reps to full GTM teams. Start free with 40 contacts per month, validate the data quality for your ICP, and scale up when the ROI is clear.
