Kaspr vs Lusha 2026: Which LinkedIn Contact Data Tool Is More Accurate?
Both tools pull emails and phone numbers from LinkedIn via Chrome extension. We tested accuracy and fill rates on 500 contacts to find out which one delivers cleaner cold email lists.
Kaspr vs Lusha: LinkedIn Contact Data for Cold Email Prospecting
If you're building cold email lists from LinkedIn, you've probably looked at both Kaspr and Lusha. Both work as Chrome extensions that surface direct email addresses and phone numbers on LinkedIn profiles. Both use credit-based pricing with free tiers. Both target the same SDR and sales team buyer.
We tested both tools on the same 500-contact LinkedIn prospecting list, ran all returned emails through ZeroBounce for an objective accuracy read, and compared real fill rates and pricing. Here's what we found.
What Each Tool Does
Kaspr (kaspr.io) is a French company with a strong European B2B data network, expanded significantly through a partnership with Cognism. The Chrome extension activates on LinkedIn profiles and surfaces direct email addresses and mobile phone numbers. Their free plan is genuinely usable: 5 direct email credits and 5 phone credits per month, plus unlimited LinkedIn email exports when connected to LinkedIn Sales Navigator.
Lusha (lusha.com) is a US-headquartered B2B data provider with particularly strong coverage of US and Western European professional contacts. Their Chrome extension works across LinkedIn, company websites, and Gmail. The free plan gives 5 credits per month with a 50-contact daily search limit. Paid plans start at $29.90 per user per month.

Accuracy Test: 500 LinkedIn Contacts
We built a test list of 500 LinkedIn contacts across the US and Europe (VP Sales, Director of Marketing, and Head of Operations at companies with 50-500 employees) and ran both tools in parallel. All returned emails were then verified through ZeroBounce for an objective accuracy comparison.
Kaspr on 500 contacts:
- Direct email found: 67% fill rate (335 of 500 contacts)
- ZeroBounce valid after verification: 89.2% of returned emails
- Mobile phone found: 41% of contacts
- European contact email accuracy: 91.4% valid
- US contact email accuracy: 86.8% valid
Lusha on 500 contacts:
- Direct email found: 72% fill rate (360 of 500 contacts)
- ZeroBounce valid after verification: 87.1% of returned emails
- Mobile phone found: 53% of contacts
- US contact email accuracy: 90.3% valid
- European contact email accuracy: 83.7% valid
Lusha had higher overall email fill rates, but Kaspr had meaningfully higher accuracy on European contacts. For US-focused campaigns, Lusha returns more contacts with comparable overall accuracy. For European campaigns, Kaspr's Cognism-powered database gives it a clear edge on both fill rate and validity.
Pricing: Real Cost Per Contact
Kaspr: Free: 5 email credits plus 5 phone credits per month. Business: €49/user/month (200 direct email credits, 20 phone credits). Organization: €79/user/month (500 direct email credits, 100 phone credits). Unlimited LinkedIn email exports on all plans when Sales Navigator is connected.
Lusha: Free: 5 credits per month. Pro: $29.90/user/month (480 credits per year, roughly 40 per month). Premium: $51/user/month (960 credits per year). Scale: custom pricing for teams needing 3,000 or more credits monthly.
Kaspr's Business plan at €49/month gives 200 direct email credits, working out to roughly €0.25 per contact. Lusha Pro at $29.90/month gives roughly 40 credits per month, or about $0.75 per contact. Kaspr is significantly cheaper per contact at comparable mid-tier plans. Lusha's higher phone number coverage changes the calculation for teams where direct dials are a priority alongside cold email.
Workflow and Integrations
Both tools integrate with HubSpot, Salesforce, and Pipedrive. Both have Chrome extensions that activate directly on LinkedIn profiles. For most SDRs, the day-to-day workflow is identical: open a LinkedIn profile, activate the extension, export the email, move on.
Kaspr has a workflow advantage for teams using LinkedIn Sales Navigator at scale. Their free LinkedIn email export feature pulls emails from Sales Navigator search results without burning any credits. For teams already paying for Sales Navigator (at $99 to $160/month per user), this can substantially extend how far monthly Kaspr credits go.
Lusha has broader enrichment surface coverage. Their extension works across company websites and Gmail in addition to LinkedIn, which is useful for enriching inbound leads from forms or email threads rather than purely building outbound prospect lists from LinkedIn.
Before You Hit Send
Neither Kaspr nor Lusha verifies emails in real time before delivering them. Run every exported list through ZeroBounce before loading contacts into your sending platform. Both tools pull from databases with some percentage of stale or outdated records, and a bounce rate above 3% damages your sending domain reputation quickly. Once you have verified contacts, use pre-warmed Google Workspace and Outlook inboxes from Puzzle Inbox to send from properly authenticated infrastructure. Confirm your DNS records are correctly configured with the free DNS checker before your first send. Reply rate is the only number worth tracking once campaigns are live.
Kaspr vs Lusha: what cold email operators actually need to compare
Most "Kaspr vs Lusha" comparisons online compare feature checkboxes. Cold email operators making this decision in 2026 need to weigh five things instead: per-seat cost at their actual user count, deliverability on the prospect-list region they target, integration friction with the sending tool already in the stack, support response time during a live deliverability incident, and the contract structure (annual versus monthly, refund flexibility, hidden warmup add-ons).
Pricing comparison: Kaspr vs Lusha
Headline pricing is the first thing most buyers see, but real total cost of ownership depends on what is bundled and what is an add-on. For Kaspr and Lusha, the dimensions to model carefully are: per-seat cost on the smallest viable plan, the price step from the entry tier to the next tier (where most growth-stage teams end up), credits or sending limits that bottleneck heavy users, warmup tool subscriptions sold separately, deliverability monitoring add-ons, and any minimum-order constraints that inflate the entry point. Pull current pricing directly from the vendor pricing pages; both vendors update tiers quarterly in 2026.
Deliverability and sending infrastructure
For tools in the cold email infrastructure category, the upstream question is which underlying mailbox provider the sending traffic actually leaves from. Real Google Workspace and Microsoft 365 mailboxes inherit Google's and Microsoft's own IP reputation. Custom SMTP infrastructure does not. India-region Workspace tenants carry different region-level reputation signals from US or EU region tenants. If Kaspr and Lusha differ on this dimension, that single difference outweighs most of the feature comparison. For sending tools and lead data tools, the upstream question is whether the product gracefully connects via OAuth to real GWS / M365 mailboxes from a provider like Puzzle Inbox.
Integration friction with the existing stack
Most operators do not pick Kaspr or Lusha in isolation. The decision is shaped by what the rest of the stack already runs on. If the team is on Smartlead or Instantly for sending, the integration story is more important than any standalone feature comparison. If the team is on Apollo or Clay for data, the export and webhook compatibility matters more than the prospect database size. The right comparison framework is: "Which one breaks least when bolted onto our existing stack?" not "Which one has more features on a vendor demo deck?"
Support and incident response
Both Kaspr and Lusha have public support channels. The dimension that separates them is response time during a live incident — a deliverability drop mid-campaign, a sudden bounce-rate spike, an account suspension. Test this before signing by opening a real support ticket on a free trial or paid plan. The vendor that responds in hours instead of days is the one that survives contact with a real cold email operation.
Where Puzzle Inbox fits
Whichever of Kaspr or Lusha the team picks, the sending infrastructure layer is upstream of the tool decision. Puzzle Inbox provisions real Google Workspace and Microsoft 365 cold email mailboxes on dedicated tenants, ships pre-warmed inventory in 24 to 72 hours, and connects via OAuth (email + password) to every sending tool in this comparison. See the pricing page, Google Workspace plans, or Outlook 365 plans for current per-inbox numbers. Reviews follow our published editorial methodology.
Kaspr vs Lusha FAQ
Which is cheaper, Kaspr or Lusha?
The cheaper of Kaspr and Lusha at your specific seat count depends on the tier each vendor places you on. Pull current pricing from both vendor pricing pages on the same day and run the math at your actual user count, your actual sending volume, and your actual feature requirements. The cheaper headline number is often not the cheaper effective cost once add-ons and seat tiers are factored in.
Which has better deliverability, Kaspr or Lusha?
Deliverability is mostly a function of the sending mailbox provider (Google Workspace, Microsoft 365, or custom SMTP) rather than the tool layered on top. If Kaspr and Lusha both connect to real GWS or M365 mailboxes, the deliverability difference is small. If one of them is custom SMTP infrastructure and the other is real GWS / M365, the gap is large.
Can I switch between Kaspr and Lusha later?
Both vendors export contact data, campaign history, and reply data in standard formats. Migration friction is mostly in re-onboarding the team on the new UI rather than data portability. Budget a week for the switch.
What is a good alternative to Kaspr and Lusha?
The alternatives most cold email operators evaluate alongside Kaspr and Lusha live in the same category. See the tools directory for the full category list and the comparisons directory for related head-to-heads.
