Jorge LewisDisclosure: GTM Bud is our product. We include it alongside competitors to give you a complete picture, and we call out its limitations honestly.
Is Kaspr worth it in 2026? For an email-led team prospecting Europe from inside LinkedIn, mostly yes: the unlimited B2B email reveals on paid plans are a genuinely rare deal, and the 4.4 average across roughly 830 G2 reviews is earned where it is measured. This Kaspr review covers the four findings that decide the purchase for everyone else: a review record that splits oddly between platforms, with 4.4 on G2 against a 3.3 built on exactly three Capterra reviews, phone accuracy that reviewers estimate at 50 to 65 percent with European numbers consistently reported more reliable than US ones, a credit meter whose expiry terms are disputed in print, and a coverage boundary that sits roughly at the Atlantic.
The evaluator’s lens here is first-hand. Our parent agency, Referral Program Pros, has booked over 7,000 meetings across more than 4,000 outbound campaigns, and we built GTM Bud on that agency playbook, backed by a written guarantee of 5 percent positive replies on LinkedIn or 1.5 percent on email, or a full refund. Contact data is a line item in every one of those campaigns. One sourcing note before the verdicts: Kaspr’s own site was not directly reachable from our research environment, so vendor claims arrive as Kaspr’s pages as indexed by search plus named 2026 coverage, with rival-published sources, Zeliq and LaGrowthMachine among them, flagged as exactly that.
What is Kaspr, and who is it built for?
Kaspr is a Chrome extension that reveals emails and phone numbers while you browse LinkedIn, Sales Navigator, and Recruiter Lite profiles, with a lightweight dashboard and some LinkedIn workflow automation behind it. It was founded in France, Cognism acquired it in April 2022, and it now operates as the self-serve, SMB-shaped product in that GDPR-first data family, marketing a database of more than 500 million emails and phone numbers, a vendor claim with no independent audit behind it. The pricing ladder runs Free, Starter, Business, and Organization, and its defining mechanic is a split meter: paid plans grant unlimited B2B email reveals, while phone numbers, personal direct emails, and exports each draw from separate credit allocations. The built-for buyer is specific: a rep or small team prospecting European markets from inside LinkedIn, email-first, who wants reveals at browsing speed without an enterprise contract.
Hold that buyer profile, because every verdict in this review is a distance measurement from it.
What do Kaspr reviews on G2 and Capterra actually say?
The headline numbers first, each tied to who printed it, as of late October 2026.
| Platform | Reported score | Reported count | As reported by |
|---|---|---|---|
| G2 | 4.4 out of 5 | Roughly 830 reviews; captures print 831 and 833, one 2026 count prints 837 | G2 listing as indexed October 2026 |
| Capterra | 3.3 out of 5 | 3 reviews | Capterra listing as indexed October 2026 |
| Capterra sub-scores | Ease of use 4.7; support 3.0; value 3.3; features 3.3 | Same 3-review base | Capterra listing as indexed October 2026 |
| Kaspr self-reported | 92 percent data accuracy | Vendor claim, no audit | Kaspr claim as relayed by FullEnrich’s 2026 comparison |
That first contrast is the strangest thing about the Kaspr review record: more than 800 reviews on one platform and three on another, for the same product. The honest reading is that the asymmetry reflects where the vendor points its review-collection energy, not a hidden quality gap, which cuts both ways: the 4.4 is a real signal from a large sample, and the 3.3 is statistical noise from a tiny one, but a review base that concentrated on one platform should be read with its sourcing in mind.
Inside the G2 record, the praise themes are consistent: ease of use, an intuitive interface, and clean LinkedIn integration recur across reviewer summaries. So are the complaint themes: outdated or incorrect contact data, phone numbers in particular, and credit allocations that high-volume users describe as expensive. Which brings this review to the question those complaints orbit.
How accurate are Kaspr’s phone numbers really?
Nobody has audited them, so here is the evidence stated as what it is. LaGrowthMachine’s 2026 review, published by a rival, estimates Kaspr phone accuracy at 50 to 65 percent, with European numbers more reliable than US ones, and places email accuracy at 75 to 80 percent. That is an editorial estimate built partly on G2 review themes, not a controlled study. The sharpest single data point in the record is an anecdote and should be weighed as one: a reviewer named Glen, posting on Capterra and GetApp on December 29, 2024, ran Kaspr on his own LinkedIn profile and got back his old mobile number, and still rated the tool 4.0 out of 5 overall. One profile is one profile, but a self-test is the one experiment every buyer can replicate for free.
Against those readings sits the vendor side: Kaspr self-reports 92 percent accuracy, as relayed by FullEnrich’s 2026 comparison, and markets real-time verification that write-ups describe as checking about 120 sources in some versions and more than 150 in others. Every number in that sentence is self-reported by a vendor and repeated by its rivals. Our advice is Glen’s method, scaled: the free tier’s 5 monthly phone credits are exactly enough to reveal yourself and four colleagues whose current numbers you know, which turns the accuracy debate into a measurement before a single dollar moves.
How much does Kaspr cost in 2026?
Kaspr costs $49 per user per month on annual billing for Starter, or $65 billed monthly, per Cleanlist’s September 2026 guide and Overloop’s September 2026 breakdown, with Business at $79 annual and $99 monthly from the same sources. The euro stickers are the same page in another currency: Landbase’s May 2026 pricing piece and Cleanlist both print Starter at 45 euros annual and 59 monthly, which resolves a disagreement older coverage left open, since $49 and 45 euros are one sticker in two denominations rather than two prices. Organization is reported at $99 to $102 and up with a five-license minimum per Tekpon. Underneath sits a free tier of 5 phone credits, 5 direct email credits, and 10 export credits per month per Kaspr help-center documentation, with its B2B email allowance disputed between unlimited, per Kaspr pricing-page copy, and 15 credits per month, per Joinsecret and LaGrowthMachine. Every figure is a reported snapshot, so verify the live checkout page.
The sticker, though, is the most stable part of the bill. Our Kaspr pricing decoder walks the full plan-by-plan math; the short version of why it needs a decoder follows.
The credit meter is the real cost driver
Two mechanics under the $49 seat move the real bill more than the sticker does, and both are disputed in print, so here are the disagreements with names attached.
Which credits you get. FullEnrich’s 2026 breakdown, Cleanlist’s 2026 guide, and Kaspr help-center documentation as indexed by search all list Starter at 1,200 phone credits and 60 direct email credits per year. LaGrowthMachine’s 2026 review prints the mirror image: 1,200 direct email credits and 60 phone credits. Those readings describe opposite products, one phone-heavy and one email-heavy, so confirm the split on the live page before signing anything that assumes either.
Whether unused credits expire. Leadhaste’s 2026 pricing breakdown states that Kaspr credits do not roll over, the reading our pricing decoder carries. Saleshandy’s 2026 breakdown reports the opposite for paid tiers, listing rollover on Starter, Business, and Enterprise with none on the free plan, and Kaspr’s own partnerships page as indexed by search says unused credits accumulate until you cancel, while Kaspr’s help center states that add-on credits bought mid-cycle do not roll over past the billing period. We print the dispute rather than resolve it, because the two readings price a quiet month very differently: under the no-rollover reading, an unused allocation is donated back to the vendor.
Whichever reading holds at your checkout, the per-unit arithmetic is ours and it is unflattering for a calling motion. Starter at $49 monthly on annual billing is $588 per year; over the 1,200 phone credits of the phone-heavy reading, that is about 49 cents per credit, 40 to 65 cents across the billing modes and tiers. Divide by the 50 to 65 percent accuracy LaGrowthMachine estimates and a number that actually connects costs roughly 75 cents to a dollar. If that meter is the reason you are reading reviews at all, our Kaspr alternatives roundup maps the exits, bounce-refund and pay-per-valid models included.
Where does Kaspr’s coverage boundary sit?
At the edge of Europe, by the weight of the available evidence. Zeliq’s 2026 comparison, published by a rival, scores Kaspr’s strength in European-market outreach, G2 reviewers report thinner data outside Europe, and LaGrowthMachine’s accuracy estimates run consistently lower for US numbers than European ones. None of that is an audit, all of it points the same direction, and it matches the product’s origin: founded in France, built outward from European markets, now owned by a UK enterprise data company. A US-led pipeline should read our Kaspr vs Lusha head-to-head before buying, because that matchup is mostly a geography call.
The European strength carries a compliance chapter that belongs in any fair Kaspr review, both halves of it. France’s data protection regulator, the CNIL, fined Kaspr 240,000 euros in December 2024 for collecting contact details of LinkedIn users who had limited their visibility, and closed its injunction in March 2026 after Kaspr brought its practices into compliance. The sanction is real and so is the documented remediation, and under GDPR you remain the data controller either way, so your lawful basis stays your responsibility whichever extension is installed.
The last boundary is the ceiling. Teams that outgrow the credit allocations, need bulk enrichment, or want human-verified mobiles are funneled, by design, toward a Cognism contract that rival-published 2026 coverage prices at roughly $15,000 to $25,000 per year in platform fees plus $1,500 to $2,500 per seat. Our Kaspr vs Cognism comparison prices both rungs of that ladder, because the $49 seat is the top of a funnel, not the whole price of the relationship.
Who should buy Kaspr, and who should skip it?
Buy Kaspr if you are the buyer it was built for: an email-led team prospecting European markets from inside LinkedIn, where the unlimited B2B email allowance removes per-reveal anxiety, the 75 to 80 percent email accuracy LaGrowthMachine estimates is workable at zero marginal cost, and the GDPR-first posture under Cognism survives EU procurement questions. For that buyer the 4.4 on G2 is earned, and the free tier makes the purchase testable before it is a purchase. For how the extension stacks against the broader finder category, our best email finder tools roundup places it in the full field.
| Your situation | Verdict on Kaspr |
|---|---|
| Email-led prospecting into Europe | Buy it; unlimited B2B emails is the category’s rarest deal |
| Phone-led motion, EU numbers | Test first; 50 to 65 percent estimated accuracy makes every credit a coin flip |
| Phone-led motion, US numbers | Skip it; the weakest cell in the accuracy estimates, per LaGrowthMachine |
| US-led pipeline generally | Compare Lusha and Apollo first; the coverage map points away from Kaspr |
| Need bulk enrichment or verified mobiles | Price the Cognism upsell before committing; that is where this ladder leads |
| No weekly operator for outreach | Wrong category; every tier hands you raw contacts and stops |
The last row is where we stop reviewing and start disclosing, because it is the gap GTM Bud was built for. A revealed contact is the cheapest step in outbound: based on data from over 4,000 outbound campaigns run by Referral Program Pros, targeting and message quality move reply rates far more than the accuracy gap between any two data vendors, and no Kaspr tier touches either job. GTM Bud runs that remainder as one AI outbound sales tool: you define your ideal customer profile, and it researches matching prospects, sources and verifies contact data inside each campaign, writes personalized messages from the playbooks our agency uses daily, and runs coordinated LinkedIn and email sequences through to booked meetings, at $600 per month per connected LinkedIn account with 1,000 leads included, a 14-day trial, and the guarantee stated above. The honest limitation is the mirror image of Kaspr’s: there is no database to browse, no reveal button, and no export, so a recruiter or researcher who needs raw contact records should take Kaspr’s free-to-Starter path and never look back.
Frequently asked questions about Kaspr
Is Kaspr legit?
Yes. The product is real, Cognism has owned it since April 2022, and daily users rate it 4.4 out of 5 across roughly 830 G2 reviews as indexed in October 2026. Two caution flags sit in the record: Capterra shows only 3 reviews averaging 3.3 out of 5, a sample too small to mean much in either direction, and France’s CNIL fined Kaspr 240,000 euros in December 2024 over contacts collected from LinkedIn users who had limited their visibility, then closed its injunction in March 2026 after Kaspr brought its practices into compliance.
How many free credits does Kaspr give you per month?
The free tier grants 5 phone credits, 5 direct email credits, and 10 export credits per month, per Kaspr help-center documentation as indexed by search. The B2B email allowance is disputed: Kaspr pricing-page copy advertises unlimited B2B emails on the free plan, while Joinsecret and LaGrowthMachine report 15 B2B email credits per month. The allocations are small, but they are exactly enough for the test this review recommends: reveal contacts you already know, your own profile included, and measure the hit rate before any money moves.
Can LinkedIn restrict your account for using Kaspr?
The risk is real enough to manage. LinkedIn’s user agreement prohibits third-party software that scrapes data from or automates activity on its platform, and contact-reveal extensions sit inside that clause as a category, Kaspr included. Keep reveal volume at human browsing pace, avoid stacking multiple extensions on one account, and treat the extension as a convenience LinkedIn tolerates rather than a right it grants.
Does Kaspr work for US prospecting?
It works, with a thinner map. Zeliq’s 2026 comparison, itself rival-published, scores Kaspr’s strength in European markets, G2 reviewers report thinner data outside Europe, and LaGrowthMachine’s 2026 estimates run lower for US phone numbers than European ones. For a US-led pipeline, third-party comparisons consistently point to Lusha or Apollo instead, and the only reliable tiebreaker is a 100-contact test in your own segment.
Who should not buy Kaspr?
Three buyers. Phone-led US teams, because metered phone credits price at 40 to 65 cents each by our own arithmetic and the estimated accuracy runs weakest on US numbers. Teams that need bulk enrichment or verified mobiles at scale, because that buyer is being funneled toward a five-figure Cognism contract. And teams with no weekly operator, because every Kaspr tier hands you raw contacts and stops; that last buyer gets more from automated lead generation that prices the outcome, sourcing, copy, and sending included, instead of the reveal.
Test it on your own list before a single credit renews
The fair close on this Kaspr review: the scores are earned where they are measured, and the boundaries are real where they are drawn. The 4.4 across roughly 830 G2 reviews reflects a genuinely easy extension with the category’s most generous email allowance, and the three-review Capterra 3.3 is noise beside it. The buying risks are specific: phone accuracy estimated at 50 to 65 percent with the US end weakest, a Starter credit split that two named sources print in opposite directions, rollover terms disputed between no-rollover and accumulate-until-cancel readings, and an upsell ladder that ends at an enterprise contract. Every one of those risks is testable on the free tier before money moves, starting with your own phone number, which is why the self-test is the only verdict in this review we insist on.
And if what your budget line actually says is meetings rather than reveals, skip the meter entirely: start with done-for-you outbound at $600 per month per connected LinkedIn account with 1,000 leads included, a 14-day trial, sourcing and verification built into every campaign, and a written guarantee of 5 percent positive replies on LinkedIn or 1.5 percent on email, or a full refund.
