Lusha and Kaspr both live in your browser extension bar, but their phone accuracy splits hard by region. Here's which one to trust, and when to graduate past both.
Picture your SDR scrolling LinkedIn, clicking a browser extension icon 40 times a day, and pasting one contact at a time into a spreadsheet. That's the job Lusha and Kaspr were both built to do faster. The question isn't which extension is "better" in the abstract. It's which one holds up in the region you actually sell into, and how long a browser extension stays the right tool before your team outgrows it.
Short answer: pick Lusha if your reps prospect mostly in the US and want the broader, more established dataset. Pick Kaspr if your team sells into Europe, where its phone accuracy runs meaningfully higher, around 90% versus 50 to 65% for Kaspr's own US phone numbers (SyncGTM, August 2026). Both tools share the same structural limit: they're built for one profile at a time, not for filtering a list of 500 contacts by title and headcount in one pass.
Lusha vs Kaspr is a comparison between two Chrome-extension-first contact finders that reveal phone numbers and emails directly on a LinkedIn profile. Lusha leans on a larger US-weighted dataset with a published (if debated) accuracy claim; Kaspr leans on stronger European coverage, particularly for direct-dial phone numbers. Neither is designed as a bulk, filterable database.
Lusha's cheapest paid tier is about $37.45 per user per month on annual billing. Kaspr's cheapest paid tier starts around $49 per month on annual billing. Both run on credit systems where phone numbers cost more credits than emails, and unused credits vanish at renewal.
Lusha's structure: Free at $0 with 40 credits a month, Starter at $37.45 per user per month annual with 4,800 credits a year, Pro ranging $52.45 to $174.95 per user per month annual depending on volume, and Premium from $299.95 to $659.95 a month for teams of five. An email costs 1 credit, a phone number costs 5, and revealing both can run up to 6 (Zeliq, August 2026). Credits don't roll over and there's no refund for bad data.
Kaspr's structure: Free at $0 with 5 phone credits, 5 email credits, and 10 export credits a month. Starter from $49 a month annual with 1,200 direct email credits and 60 phone credits a year. Business from $79 a month. Organization at $99 a month annual with 4,800 phone, 4,800 email, and 24,000 export credits per user (Leadhaste, August 2026). Kaspr's edge here: credits reportedly roll over on paid plans, which Lusha doesn't offer.
The number that should actually change your decision isn't the sticker price. It's the phone credit ratio. If your outbound motion leans on calling, not just emailing, Kaspr's cheaper access to phone credits and stronger European accuracy might outweigh Lusha's lower entry price.
| Tool | Entry paid price | Phone credit cost | Rollover | Accuracy claim |
|---|---|---|---|---|
| Lusha | ~$37.45/user/mo annual | 5 credits per number | No | 98% email / 86% phone advertised |
| Kaspr | ~$49/mo annual | Included in phone credit pool | Yes, on paid plans | Not independently audited; varies by region |
| InboundLabs | Free to start, no credit card required | Verified direct dials, not switchboard numbers | Monthly plans, no annual lock-in | 98% email deliverability on verified contacts |

Kaspr is stronger for phone numbers in Europe. Lusha's advertised accuracy is higher on paper, but real-world reviews consistently report a gap between the claim and what reps actually experience.
Lusha advertises 98% accuracy on email and 86% on phone numbers. Independent reviews tell a different story: one Capterra reviewer running their own metric tracking found real accuracy closer to 80%, but with only about 10% database coverage, meaning out of 100 target contacts, Lusha had data on roughly 10, and about 8 of those were accurate (Cold Email Manifesto, August 2026). G2 reviewers report similar gaps, with roughly a third of accuracy-related complaints citing phone numbers that connected to the wrong person or a dead line (Cold Email Manifesto, August 2026).
Kaspr's accuracy is regional in a way that's worth stating plainly: phone number accuracy in Europe runs around 90%, with roughly 85% of numbers connecting to the correct person in detailed testing. In North America, that number drops to 50 to 65%. Email accuracy sits at 75 to 80% (SyncGTM, August 2026). If you're selling into the UK, France, or Germany, Kaspr's phone data is the more defensible bet. If you're selling into the US, neither tool's phone accuracy is something you should trust without verification.
Independent B2B email accuracy studies more broadly show a wide range, and the industry standard for a healthy bounce rate on a verified list stays under roughly 1 to 2% (Leadhaste, cold email bounce benchmarks, August 2026). Any extension-sourced list you haven't independently verified should be treated as a starting point, not a send-ready list.
Pick Lusha if your team sells primarily in North America, you want the larger dataset and don't mind the accuracy gap between claim and reality, and you're comfortable spot-checking numbers before a call block. Lusha's UI and CRM-adjacent workflow make it easy to onboard a new rep within a day.
Pick Kaspr if your team sells into Europe, phone-first outreach matters to your motion, and rollover credits matter to your budget. Kaspr's European accuracy is a real, cited advantage, not a marketing line.
Who should NOT use InboundLabs: if your entire workflow depends on a one-click browser extension sitting directly on top of a LinkedIn profile page, InboundLabs won't replicate that exact motion today. We're built for filtering and exporting a list by industry, headcount, region, and title, not for revealing a single profile's data mid-scroll.
Here's the pattern in nearly every team that starts with a LinkedIn extension: it's fast for the first rep, tolerable for the second, and painful by the third. Clicking through 200 profiles a day to build a list isn't a workflow, it's a bottleneck wearing a workflow's clothes.
The Browser Extension Ceiling is the point where a profile-by-profile tool stops matching your team's volume. It usually shows up around 1 to 3 reps doing manual lookups, somewhere between 150 and 300 contacts a week per person, depending on list quality needs. Below that ceiling, an extension really is the fastest tool available. Above it, you need something that filters and exports in bulk instead of clicking one profile at a time.
"An extension that's fast for one rep is a bottleneck for five. The ceiling isn't about the tool being bad, it's about the workflow not scaling."
If you've hit that ceiling, if you're clicking through profiles one at a time and your team has grown past what one extension can support, that's exactly the gap between a lookup tool and a database. InboundLabs lets you filter by industry, headcount, region, and title and pull a list at once instead of one profile at a time.

Lusha and Kaspr solve the same problem from different regional strengths, and picking between them mostly comes down to where your team sells and how much your outbound motion leans on phone calls. Neither one is built to replace a bulk-filterable contact database once your team scales past a handful of reps doing manual lookups. If that's where you are, or you're about to get there, InboundLabs is worth testing free before you add a third seat to either extension.
Kaspr is stronger in Europe, with roughly 90% phone accuracy and 85% correct-person connection rates in detailed tests. Kaspr's own North American phone accuracy drops to 50 to 65%. Lusha advertises 86% phone accuracy overall, but independent reviews report real-world gaps below that figure.
Lusha credits do not roll over and expire at renewal with no refund for bad data. Kaspr's paid plans reportedly allow credit rollover, which is a meaningful budget advantage if your usage varies month to month.
Both tools are built around one-profile-at-a-time lookups via a Chrome extension, not bulk filtering. You can export saved lists, but building a filtered list of hundreds of contacts by title and headcount is faster in a dedicated database tool.
Kaspr sources phone data from over 150 providers, and European mobile number registries and data-sharing norms produce more reliable matches than US sources, where personal phone data is more fragmented and harder to verify at scale.
It's the advertised figure for email specifically. Independent reviews, including Capterra and G2 user reports, show real-world accuracy commonly landing closer to 60 to 80% depending on region and contact type, which is why spot-checking before a send is worth the extra minute.
You'll notice it as a bottleneck: reps spending more time clicking through profiles than actually calling or emailing. That's the point to move to a filterable, bulk-exportable contact database instead of adding more extension seats.
Yes. InboundLabs offers verified B2B contact data with buyer intent signals on monthly plans with no annual lock-in, and is free to start with no credit card required, positioned as a bulk-filtering alternative to profile-by-profile extensions.
