Kaspr vs Prospeo: Which B2B Data Tool Wins in 2026?
Your SDR burned through their Kaspr credits by Wednesday. Now they're guessing at email formats while the pipeline dries up. We've watched this play out with enough teams to know the pattern - and the top Google result for this comparison actually pits Kaspr against Prospectoo, a completely different product. So let's do this properly.
Here's what each tool actually delivers, what it costs when you run the math, and which one fits your workflow.
30-Second Verdict
If your workflow is email-first or you operate outside Europe, Prospeo wins on accuracy (98% vs ~90%), database size (300M+ vs 120M+), and cost (~$0.01/verified email vs Kaspr's multi-bucket credit maze). Kaspr's strength is EU phone prospecting from professional profiles - it's genuinely good at that narrow job. But for global coverage, verified mobile numbers, intent data, and predictable pricing, Prospeo is the stronger pick.
The gap between Kaspr's 4.4 on G2 and its 1.5 on Trustpilot tells you everything about the difference between the product experience and the billing experience.
Feature-by-Feature Comparison
| Feature | Kaspr | Prospeo | Winner |
|---|---|---|---|
| Database size | 120M+ (EU-focused) | 300M+ (global) | Prospeo |
| Email accuracy | ~90% | 98% | Prospeo |
| Verified mobile numbers | Not published | 125M+ (30% pickup) | Prospeo |
| Data refresh | Not published | Every 7 days | Prospeo |
| Pricing model | Multi-bucket credits | Flat ~$0.01/verified email | Prospeo |
| Free tier | 5 phone + 5 direct email + 10 exports/mo | 75 emails + 100 credits/mo | Prospeo |
| Cancellation | Complaints documented | Self-serve, no contracts | Prospeo |
| CRM integrations | HubSpot, Salesforce, Pipedrive, Lemlist, Brevo + more | Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, Make + more | Tie |
| Intent data | Enterprise plan only | 15,000 topics (Bombora) | Prospeo |
The database gap matters most outside Europe. Kaspr's 120M+ contacts are heavily concentrated in the EU, so if you prospect in North America, APAC, or LATAM, you'll feel that limitation fast.
Kaspr - What You Get
Use Kaspr if you're a solo rep or small team running phone-heavy outreach into European markets. The Chrome extension is smooth - users on G2 praise its simplicity. Kaspr's data is checked against 120 sources, and a Cognism partnership strengthens its phone database. For EU phone prospecting specifically, it's competitive.
Skip Kaspr if you need volume. The credit system splits into four separate buckets - phone credits, direct email credits, B2B email credits, and export credits - each with different limits and refill rates. A single profile lookup can burn 2-3 credits because email and phone reveals are charged separately. That adds up fast.
The free plan gives you 5 phone credits, 5 direct email credits, and 15 B2B email credits per month (plus 10 export credits). One thing that trips people up: Kaspr's "B2B emails" are generic company addresses like info@company.com, not personal work emails. You can unlock unlimited B2B emails by inviting three colleagues with gold invitations, but that doesn't help if you need direct addresses for outbound sequences.
And the billing experience? Trustpilot reviews consistently flag auto-renewal charges, refund refusals, and difficulty cancelling. One reviewer cited an unexpected EUR1,080 charge. That 1.5/5 rating across 86 reviews isn't random noise.
Kaspr's credit buckets burn fast - separate pools for phones, direct emails, B2B emails, and exports. Prospeo gives you 300M+ profiles, 98% email accuracy, and 125M+ verified mobiles on a single, flat credit system at ~$0.01 per email.
Stop rationing credits. Start building pipeline that actually converts.
Prospeo - What You Get
The database covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers. Email accuracy sits at 98%, powered by a proprietary 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering. Everything refreshes on a 7-day cycle - the industry average is closer to six weeks.
The search interface gives you 30+ filters including buyer intent, technographics, job changes, headcount growth, and funding signals. Intent data tracks 15,000 topics through Bombora, so you can layer "who's in-market" on top of "who matches my ICP." Kaspr reserves that kind of filtering for custom Enterprise pricing.
The Chrome extension works across company websites and CRMs, pulling 50+ data points per contact. Self-serve onboarding, no contracts, cancel anytime from your dashboard.
Pricing Breakdown
Here's where the comparison gets uncomfortable for Kaspr. Let's walk through a simple scenario: you need 500 verified personal work emails per month.
Important distinction: Kaspr separates "direct emails" (personal work addresses like jane@company.com) from "B2B emails" (generic addresses like info@company.com). If you're doing real outbound, you need direct emails. (If you’re evaluating other providers too, see our breakdown of data enrichment services.)
On Kaspr's Starter plan (EUR45-59/user/month), you get unlimited B2B emails but only 5 direct email credits per month. That means buying 495 add-on credits at roughly $0.21-$0.36 each - about $104-$178 in add-ons on top of your base plan.
| Scenario: 500 direct emails/mo | Kaspr (Starter) | Prospeo |
|---|---|---|
| Base plan | ~EUR45-59/mo | $0 (free tier) or paid plan |
| Direct email credits included | 5 | 75 (free) or more |
| Add-on cost for remaining | $104-178 | ~$5 at $0.01/email |
| Total estimate | ~$150-240/mo | Under $50/mo |
We've seen teams burn through Kaspr credits without realizing phone lookups, email lookups, and exports all draw from different pools. The four-bucket system is the single biggest source of billing frustration we hear about.
Look - if your team sends more than 200 emails per month, Kaspr's credit economics simply don't work. The tool was designed for low-volume, phone-first EU prospecting. Stretching it beyond that use case is where the pain starts. (If you’re building a broader outbound stack, start with our list of SDR tools.)
What Real Users Report
Kaspr sentiment is genuinely split. On G2, it holds a 4.4/5 from 833 reviews - users love the Chrome extension's simplicity and the quality of EU phone data. The top negatives are credit limitations, pricing at scale, and lead management gaps. On Trustpilot, the story is darker: billing disputes, auto-renewal charges, and GDPR complaints about personal numbers being shared without consent. The consensus on r/sales threads tends to echo the Trustpilot side more than the G2 side.
Prospeo proof points tell a different story. Snyk's 50 AEs went from 35-40% bounce rates to under 5%, generating 200+ new opportunities per month. Meritt tripled their pipeline from $100K to $300K/week after switching providers, with bounce rates dropping from 35% to under 4%. Stack Optimize built to $1M ARR with 94%+ deliverability and zero domain flags across all clients. These aren't hypothetical improvements - they're the kind of results that compound when your data is actually clean. (If you want the mechanics behind this, read our email deliverability guide and email bounce rate benchmarks.)
The Verdict
Pick Kaspr if you're a solo rep focused on EU phone prospecting, your monthly volume stays under 100 lookups, and you're comfortable managing four credit buckets.
Pick Prospeo if your outreach is email-first, you need global coverage, team economics matter, or you don't want to fight to cancel a subscription. For most B2B teams running outbound at any real scale, this is the better tool. (To tighten targeting before you buy more data, use an ideal customer profile scoring rubric.)
Here's the thing - when your credits run out midweek and you start guessing at email formats, every bounced message chips away at your domain reputation. A 98% accuracy rate and a 7-day refresh cycle aren't just better numbers on a spec sheet. They're the difference between sequences that land in inboxes and sequences that get flagged. (If you’re scaling volume, follow safe email velocity limits.)
The teams above didn't just switch providers - they eliminated 30%+ bounce rates overnight. Prospeo's 7-day data refresh and 5-step verification mean every email you send actually lands. No surprise charges, no auto-renewal traps, no contracts.

FAQ
Is Kaspr actually free?
Technically yes - 5 phone, 5 direct email, 15 B2B email, and 10 export credits per month. That's roughly 5 usable prospect lookups. Prospeo's free tier gives you 75 verified emails and 100 Chrome extension credits monthly, which is enough for real outbound testing before you commit.
Which tool has more accurate emails?
Prospeo delivers 98% accuracy through a proprietary 5-step verification process with catch-all handling and spam-trap removal. Kaspr lands around 90% in third-party benchmarks, with its strongest results in European markets. For teams where deliverability is non-negotiable, that 8-point gap compounds fast - especially across thousands of sends per month.
Does Prospeo have phone numbers?
Yes - 125M+ verified mobiles globally with a 30% pickup rate. Phone lookups cost 10 credits each, and you only pay when a valid number is found. Kaspr doesn't publish its mobile database size, which makes a direct comparison difficult.
Can I cancel Kaspr easily?
Multiple Trustpilot reviewers report difficulty cancelling, unexpected auto-renewal charges, and refund refusals. Prospeo is fully self-serve - cancel anytime from your dashboard with no contracts or retention calls.
