The Best Free Company Contact Databases Worth Your Time
B2B contact data decays at 2.1% per month - roughly 22.5% annually. That means if you downloaded a list of 1,000 contacts in January, more than 200 of those records are wrong by December. Sales reps lose an estimated 500 hours per year correcting bad contact info. So "free" has a real cost. Here's where the value actually is.

8 Best Free Contact Databases for 2026
Prospeo
Prospeo's free tier gives you 75 verified emails and 100 Chrome extension credits per month - no credit card, no contract. That's enough to run a real micro-campaign, not just kick tires.

The database covers 300M+ professional profiles with 98% email accuracy on a 7-day refresh cycle. Most competitors refresh every four to six weeks, which is a massive gap when you're relying on data freshness to protect your sender reputation. The Chrome extension (40,000+ users) works across company websites and professional profiles, pushing contacts straight into Salesforce, HubSpot, Smartlead, or Instantly. One proof point worth mentioning: Meritt dropped their bounce rate from 35% to under 4% after switching, and tripled their pipeline from $100K to $300K per week.
Use this if: You need verified emails that won't wreck your domain reputation, and you want a free tier that's genuinely functional for outbound.
Apollo.io
Apollo is the default recommendation for teams that want volume. The free plan includes around 1,200 credits for searching and revealing contacts, plus limited mobile access depending on what you're doing inside the platform. Paid plans start at $49/user/month.

Here's the catch: credits don't roll over, and Apollo's waterfall enrichment can burn credits unpredictably depending on your target market's coverage. The bigger issue is data quality - G2 reviewers often mention outdated emails and phone numbers. Apollo is great for building big lists fast. Less great when your sequence bounces 15% on day one.
Use this if: You're testing outbound for the first time and want a big database to explore without paying anything.
Skip this if: Deliverability is a priority. We've seen teams burn sender reputation on unverified data before realizing the problem.
Hunter.io
Hunter's free plan gives you 50 unified credits per month - one search costs 1 credit, one verification costs 0.5. Paid plans start at $49/month for 2,000 credits.
Hunter's strength is domain-based email search. Plug in a company domain and get every email pattern it can find. It's clean, focused, and doesn't try to be a full prospecting platform. That simplicity is either a feature or a limitation depending on your workflow.
Best for: Teams that already know which companies they're targeting and just need emails for specific domains. Not built for list-building from scratch using filters like job title or industry.
Lusha
Lusha's free tier stands out for one reason: phone credits. Most free plans restrict mobiles entirely. You get 70 credits per month, and some pull direct dials - a rare perk at this price point. Paid plans start at $22.45/user/month on annual billing.
If you're an SDR who needs a handful of direct dials each week without paying for a full platform, Lusha is the answer. Seventy credits disappear fast at scale, though. This is a tool for targeted calling, not volume prospecting.
GetProspect
GetProspect offers 50 free valid emails per month with a simple, no-frills interface. The tool does one thing - email-only prospecting - and does it adequately.
The problem is the upgrade path: the jump from free to paid is $279/month. That's a steep cliff for what you get. Fine for testing; expensive to grow into.
RocketReach
Five free lookups per month. Let's do the math: that's one contact every four working days. Barely enough to test the product, let alone prospect. Paid plans start at $80/month for 125 lookups, and mobile numbers only unlock on higher tiers. Additional credits run $0.30-$0.45 each. Use this for one or two specific contacts you absolutely need. For anything resembling regular outbound, five lookups is a rounding error.
Outscraper
First 500 contacts free, then $3 per 1,000 domains. Outscraper is scraping-based - useful for pulling local business data from public sources, better for local business lists than role-based SaaS prospecting. If you're targeting restaurants, dentists, or contractors in a specific metro area, it works. For B2B SaaS outbound, look elsewhere.
Kaspr
Limited free plan with a European focus. Paid plans start at EUR 45/user/month and include unlimited email credits. If you're prospecting into EMEA, Kaspr is worth a look - their data coverage in France, Germany, and the UK is stronger than most US-first tools.
A couple of other tools with free tiers worth noting: RB2B (150 credits/month) and Dropcontact (50 credits first month, then 25/month).

Most free contact databases cost you more than they save - 22.5% annual data decay means bounced emails, burned domains, and lost deals. Prospeo's free tier gives you 75 verified emails monthly at 98% accuracy on a 7-day refresh cycle. Real data, not stale records.
Stop paying for free data with your sender reputation.
Public Sources Worth Knowing
Data.gov and the EU Open Data Portal are genuinely free and unlimited. They're great for firmographic research and public datasets - things like company registrations, industry classifications, and government contract awards. What they don't contain: verified work emails, direct dials, or anything purpose-built for outbound sales.
The Hidden Cost of Free Data
Bad data costs organizations an average of $12.9M annually. For a 5-person sales team, bounced emails mean damaged sender reputation, which means your legitimate emails start landing in spam. That's a compounding problem - and it sneaks up on you.

Here's the thing: if your bounce rate is above 5%, your free database isn't saving you money. It's costing you deals. Signs your data is stale: reply rates dropping month over month, bounce rates climbing past 3%, and "left the company" auto-replies on more than 10% of sends. We've watched teams spend weeks warming a domain, only to torch it in a single campaign built on unverified contacts.

The compliance angle matters too. EU regulators have issued EUR 2.8B+ in GDPR fines since 2018, with penalties reaching EUR 20M or 4% of global turnover. Stick with providers that enforce opt-outs and maintain GDPR compliance - it's not optional if you're selling into Europe.

Meritt cut their bounce rate from 35% to under 4% and tripled pipeline to $300K/week. The difference wasn't working harder - it was switching from decayed contact data to Prospeo's 300M+ profiles verified every 7 days. Start free, no credit card required.
Your free database shouldn't cost you $12.9M in bad data.
When to Upgrade from Free
Stay on a free plan if you're prospecting under 50 contacts per week, testing whether outbound works for your business, or you're a solo founder validating a market.

Upgrade when you're running a team of 2+ reps, sending 200+ emails per week, or noticing your domain reputation slipping - which happens faster than most teams realize. Needing mobile numbers for cold calling is another clear signal. A free company contact database gets you started, but sustained outbound at scale demands verified, regularly refreshed records. The math is simple: one closed deal pays for a year of most paid plans on this list.
FAQ
Is there a truly free contact database with no limits?
No. Most tools cap free access between 5 and roughly 1,200 credits per month. Public registries like Data.gov are unlimited but lack verified work emails or phone numbers. The most usable free tiers come from Prospeo (75 emails/month) and Lusha (70 credits/month), both functional enough for small-scale outbound.
How accurate are free B2B contact databases?
Expect 70-85% accuracy from most free tiers, since B2B data decays at 2.1% monthly and free plans aren't always maintained as aggressively. Providers with weekly refresh cycles hold accuracy closer to 98%. Always verify before sending - a single bad campaign can tank your domain reputation for weeks.
Do free contact databases include phone numbers?
Rarely. Most tools restrict mobile numbers to paid plans. Lusha's free tier is the main exception, including some phone credits in its 70 monthly allotment. For dedicated mobile access, expect to pay.
Can I use free B2B databases for cold email legally?
Yes, in most jurisdictions. B2B cold email is legal under GDPR's legitimate interest basis (Recital 47) and CAN-SPAM, provided you include opt-out mechanisms and process data responsibly. Avoid scraped lists from unknown sources - stick with GDPR-compliant providers and you're on solid ground.
