Apollo vs. Lusha vs. Kaspr: Which B2B Data Enrichment Tool in 2026?

Apollo, Lusha, or Kaspr: Which One Should You Choose in 2026?

In short: pick Apollo if you're prospecting at volume internationally, Lusha if you want the simplest solution, and Kaspr if your targets are European and GDPR compliance is a priority. All three enrich B2B contacts (email, phone, job title), but each excels at one specific thing. Apollo bets on a massive database and built-in sequences. Lusha sells simplicity. Kaspr, a French company, focuses on LinkedIn-sourced mobile numbers and European data.

The classic trap: choosing based on the advertised contact count. A database of 250 million profiles is worthless if your French prospects are poorly covered or the emails are two years stale. In France, two criteria matter more than volume: data freshness and the legal basis for processing.

How Does Data Coverage Compare Across Tools?

Apollo offers the largest database, but its strength lies in the US. Its database exceeds 250 million contacts, extremely dense for US companies and large tech accounts. Coverage degrades for French SMBs and non-English-speaking roles. Lusha offers a smaller but better-calibrated database focused on decision-makers, with a good match rate in Western Europe. Kaspr stands out in the French and European market, largely thanks to its LinkedIn foundation.

The right move: test each one against your actual target market. Export 50 profiles from your market, run the enrichment, and measure the match rate. A "smaller" tool specialized in your region often beats the generalist giant. To build a clean target list upfront, our guide to automated prospecting explains how to segment before enriching.

Emails and Mobile Numbers: Which Tool Has the Best Data Quality?

On mobile numbers, Kaspr dominates; on professional emails at volume, Apollo holds the edge. Kaspr is known for mobile numbers sourced from LinkedIn — historically a weak spot for American databases. Apollo delivers plenty of emails, but with a growing share of stale contacts outside the US market. Lusha sits in between: less volume, but a solid and consistent validity rate.

One number worth remembering: for professional email, a bounce rate above 5% degrades your entire domain's deliverability. Always verify addresses before sending, regardless of the tool. Unvetted "raw" enrichment can ruin a campaign. To understand the impact on your response rates, compare against our cold email and LinkedIn benchmarks.

How Much Do Apollo, Lusha, and Kaspr Cost?

Expect to pay anywhere from €0 to a few dozen euros per user per month, with a highly variable credits-to-price ratio. Apollo remains the cheapest at volume: its free tier is generous and paid plans start around €40 to €50/month/user with plenty of credits. Lusha sits a bit higher, starting around €30 to €40/month, with more limited credits. Kaspr offers an accessible entry point, often around €45 to €60/month, with a mobile-number focus that justifies the premium for European profiles.

The sticker price is misleading: what matters is the cost per valid contact on your target market. A "cheap" plan with 40% unusable data ends up costing more than a premium plan with 90% validity.

Are Apollo, Lusha, and Kaspr GDPR-Compliant?

Compliance depends mostly on how you use the tool, but Kaspr starts with a structural advantage in the European market. In B2B prospecting, GDPR applies as soon as you process personal data (name, professional email, mobile number). The usual legal basis is legitimate interest, provided you inform the individual and honor their right to object. Kaspr, a French vendor, claims a European foundation and GDPR-aligned processes, which simplifies your own compliance.

Apollo, with its predominantly American data, calls for more vigilance: transfers outside the EU, collection sources, retention periods. This doesn't rule it out, but it commits you to documenting your processing. Lusha sits in an intermediate zone. In every case, the tool doesn't let you off the hook: as the data controller, you're the one who must be able to justify the legal basis. Before buying or enriching data at scale, read our article on legally buying an email database and the framework for cold email under GDPR.

Which Tool Fits Which Profile?

The right choice comes down to your market and your level of automation, not the brand name. Here's a simple recommendation based on three common profiles among French small and mid-sized businesses.

You Prospect Broadly and Internationally

Choose Apollo. Its massive database and built-in sequences make it a Swiss Army knife for teams sending high volumes and managing campaigns from one place. The volume-to-price ratio is unbeatable if your targets are US-based or English-speaking. For the French market alone, pair it with an email verification tool.

You Want the Simplest Solution

Choose Lusha. The browser extension installs in minutes and enriches a LinkedIn profile with a single click. For a small sales team with no time for onboarding, it's the shortest path to usable contacts. The trade-off: credits run out fast and volume is less generous.

Your Targets Are European and GDPR Is a Priority

Choose Kaspr. Its LinkedIn-sourced mobile numbers and European foundation make it the most reassuring option for prospecting in France and the EU. It's also the best ally for a multichannel sequence.

FAQ

Can You Use Apollo, Lusha, or Kaspr for Free?

Yes, all three offer a free tier with a limited number of monthly credits. Apollo is the most generous with free volume. Lusha and Kaspr offer enough credits to test quality against your actual target market before paying. Use these trials to compare match rates.

Which One Is the Most Reliable for Mobile Numbers?

Kaspr is generally the strongest on mobile numbers, especially those sourced from LinkedIn profiles in Europe. Apollo remains weak on mobiles outside the United States. Lusha offers decent coverage. If your main channel is cold calling in France, Kaspr is often the best choice.

Is Enriching Contacts With These Tools Legal in France?

Yes, as long as you comply with GDPR: legal basis (often legitimate interest in B2B), informing individuals, and honoring the right to object. The tool doesn't automatically make you compliant. You remain the data controller and must be able to document your processing, including for data collected outside the EU.

Should You Choose One Tool or Combine Several?

Combining tools can make sense to maximize coverage — for example, Apollo for volume and Kaspr for European mobile numbers. But for an SMB, a single well-chosen tool is often enough. Only add more sources if your match rate on your target market stays too low.

How Do You Choose Without Getting It Wrong?

Test all three against your actual target market before committing, then decide based on cost per valid contact, not the sticker price. Apollo for international volume, Lusha for simplicity, Kaspr for Europe and GDPR compliance: the right answer depends on your market and your primary channel.
