The best business contact databases, tested and ranked
We searched for the same 200 business contacts, whose details we already knew, in twelve contact databases and checked every email, phone and job title. Here's which one found the most correct data, which fits your budget, and what each costs to start.
About this list
A B2B contact database holds business emails, phone numbers, job titles and company details that sales teams, recruiters and marketers search and export. Our contact databases section has more on each tool, and the sales software hub covers the wider field.
Contact data goes stale as people change jobs, so accuracy matters more than size. To compare them fairly, we used a fixed list of 200 business contacts and 50 companies, across company sizes and regions, where we already knew the correct email, phone and title. From October 24 to October 30, 2026, every tool searched the same list, and we checked what it returned.

Test results side by side
ZoomInfo was far ahead of the field. It found 188 of our 200 contacts, got the title and company right for 186 of them, had valid emails and phones for 167, and passed all 8 of our data-source and opt-out checks. No other tool found more than 141 contacts.
Behind it, the other eleven were bunched together. Most found between 110 and 141 contacts, and only about half to two thirds of the contacts each one found had a valid email. The surprise was D7 Lead Finder, a cheap local-business tool, which found 141 contacts and came third.
Every tool got the same test, between October 24, 2026 to October 30, 2026.

Also worth knowing about
We didn't test these tools, but they come up often and may suit a specific need.
Apollo.io
A contact database combined with outreach tools. We haven't tested it.
Lusha
A self-serve contact lookup tool with a free plan. We haven't tested it.
How we tested
Every tool searched the same fixed list between October 24 and October 30, 2026: 200 business contacts and 50 companies, across sizes and regions, where we already knew the correct email, phone and title. You can read the full set-up in how we test.
We counted how many contacts each tool found, checked emails, phones, titles and company records against what we knew, and ran 8 checks on data sources, opt-out process and privacy policy. Each tool then got a score out of 5, in half points, for data accuracy, coverage, ease of use, compliance and value for money, which make up the overall score and ranking.
How to choose
Use a trial or free plan to search people whose details you know. In our test, valid emails ranged from 167 contacts for ZoomInfo down to 62 for KnowFirst.
Region matters. Cognism focuses on the UK and Europe, Lead411 on the US and KnowFirst only on Australia and New Zealand, while D7 Lead Finder and Coldlytics target local businesses.
ZoomInfo, Cognism and Seamless.AI need a sales conversation. If you'd rather see the price first, UpLead, Lead411, Coldlytics and Coresignal publish monthly plans.
Annual auto-renewals drive many complaints, especially for Seamless.AI and RocketReach. Start on monthly billing where you can and diary any cancellation deadline.

In our test, ZoomInfo was clearly best. It found 188 of our 200 known contacts, got 186 titles and companies right and passed all 8 compliance checks. Cognism came second and suits teams calling Europe, and D7 Lead Finder came third for local business leads.
How much do B2B contact databases cost?
Published prices start at $39 a month for RocketReach Essentials, per a third-party listing, with D7 Lead Finder at $44.99 a month and Lead411, Coldlytics and Coresignal at $49 a month. UpLead Essentials is $99 a user a month. ZoomInfo, Cognism and Seamless.AI sell paid plans only by quote.
Is there a free B2B contact database?
Several tools let you start free. Coldlytics has a free plan with 25 credits a month, Seamless.AI gives 50 credits, KnowFirst 20 credits and Vibe Prospecting 100 credits on sign-up. RocketReach offers 5 free lookups, and UpLead, Lead411 and Coresignal have 7-day trials.
How accurate are B2B contact databases?
Less accurate than their marketing suggests. In our test, only ZoomInfo found more than 141 of our 200 known contacts, and most tools had a valid email for only about half to two thirds of the contacts they found. Check a sample before a big campaign.
How did we test these databases?
From October 24 to October 30, 2026, every tool searched the same list of 200 business contacts and 50 companies whose correct details we already knew. We counted matches, checked emails, phones, titles and company records, and ran 8 checks on data sources, opt-out process and privacy policy.
Are B2B contact databases GDPR compliant?
Vendors say they are, but it varies. Cognism claims ISO 27001, ISO 27701 and SOC 2 Type II and scrubs against Do Not Call lists, and ZoomInfo passed all 8 of our compliance checks yet faces lawsuits over data collection. Even with a compliant supplier, you still need a lawful reason to contact people.
The bottom line
If you can sign an annual contract, ZoomInfo gives the most accurate data; smaller teams should test UpLead, Lead411 or RocketReach on their own contacts first.

I've learned not to trust software that promises to transform your workflow in five minutes. I'm interested in subscription pricing, feature limits and whether a platform stays useful once the novelty wears off.
