Kaspr vs Nymeria: Pricing, Credits, Accuracy, and Integrations
Updated June 2026
Here's a scenario we've seen play out in RevOps Slack channels more than once: someone runs a side-by-side test of Kaspr and Nymeria, expecting a clean winner. Kaspr burns through phone credits fast. Nymeria surfaces personal Gmail addresses when the team wanted only professional emails. Pricing gets steep at volume, support is slow when things break, and neither tool was actually wrong - they just solve different problems. The real challenge with this comparison is that these two tools barely overlap.
30-Second Verdict
- Pick Kaspr if you're doing European B2B prospecting and want native CRM integrations out of the box.
- Pick Nymeria if you're recruiting, need personal email addresses, or run API-first enrichment workflows.
- Skip both if you're optimizing for verified accuracy and cost per valid contact. More on that below.
Head-to-Head Feature Comparison
When we evaluate data tools, review volume is a proxy for how predictable support and billing issues will be. Keep that in mind as you read this table.
| Feature | Kaspr | Nymeria | Winner |
|---|---|---|---|
| G2 Rating | 4.4/5 (833 reviews) | 4.7/5 (6 reviews) | Kaspr (signal you can trust) |
| Starting Price | Free; paid from EUR 45/mo (annual) | $39/mo | Nymeria (lower entry) |
| Free Tier | 5 phone credits/mo | 5 credits/mo | Kaspr (phone data included) |
| Database Focus | European B2B | Personal + work emails | Depends on ICP region |
| Data Types | Work emails, direct dials | Personal + work emails, mobiles, social links | Nymeria (broader types) |
| Chrome Extension | Yes (40K+ users) | Yes (all major browsers) | Kaspr (larger user base) |
| CRM Integrations | HubSpot, Salesforce, Pipedrive | API-first | Kaspr (plug-and-play) |

| Data Refresh | Not published | Not published | Neither |
You're not comparing two identical databases here - you're choosing a workflow. Kaspr is built for sales teams who live inside a CRM. Nymeria is built for developers and recruiters who live inside an API console.
The review gap tells a real story, too. Kaspr's 833 G2 reviews give you enough signal to read dozens of complaints about credit burn and still feel confident the tool works for its core use case. Nymeria's 6 reviews make it a procurement risk if you need stakeholder buy-in. That's not a quality judgment - it's about verifiability.
Kaspr: European Prospecting Workhorse
Use Kaspr if you're an SDR or sales team focused on European markets. The database covers 120M+ European contacts, the Chrome extension has 40,000+ users, and paid plans include unlimited B2B email credits (subject to fair use) while phone credits are capped by plan. Native integrations with HubSpot, Salesforce, and Pipedrive mean you're not duct-taping workflows together.
Pricing tiers run Free (EUR 0), Starter (EUR 45/mo annual or EUR 59/mo monthly), Business (EUR 79/mo annual or EUR 99/mo monthly), and custom Enterprise. Check Kaspr's pricing page for current credit allocations per tier, as these shift frequently.
Skip Kaspr if you prospect primarily outside Europe or need high phone credit volume. The free plan's 5 phone credits per month isn't a trial - it's a tease. Even on paid plans, phone credits are capped well below email credits, and G2 reviewers consistently flag how fast they burn through them. One Reddit user put it bluntly: the pricing gets steep for volume, and customer service is slow when you need help. If you're burning through hundreds of phone numbers monthly, Kaspr's credit model will frustrate you.
Tired of Kaspr burning through phone credits? Prospeo gives you 125M+ verified mobiles with a 30% pickup rate - plus 143M+ emails at 98% accuracy. No fair-use caps, no credit guessing games. At ~$0.01/email, you'll spend 90% less than legacy tools.
Stop rationing credits. Start reaching every decision-maker on your list.
Nymeria: Recruiting and Personal Email Specialist
Use Nymeria if you're a recruiter or marketer who needs personal email addresses. Most B2B tools skip personal emails entirely - Nymeria leans into them (Gmail, iCloud, Hotmail) alongside work emails. Their "no email guessing" policy is a genuine differentiator: they don't guess emails or fuzzy-match people profiles.
For developers, the API is clean. Use require parameters (e.g., personal-email, phone) so calls return 404 when the required field isn't available - you're not paying for empty results. Auth runs through an X-API-Key header, responses include credit-spend telemetry, and a 402 means your plan lapsed or credits are exhausted. This is a developer-friendly tool, not a point-and-click one.
Pricing runs Nano ($39/mo), Micro ($79/mo), Kilo ($159/mo), and custom Enterprise, with 20% savings on annual billing. Expect Nano/Micro/Kilo to roughly map to ~1,000 / ~5,000 / ~10,000 successful enrichments per month.
Skip Nymeria if you need scale, social proof, or native CRM integrations. Around 700+ companies use it. One G2 reviewer says it's "usually helpful 90% of the time" - useful color, not a benchmark. Let's be honest: Reddit isn't helpful for due diligence either. Most "Nymeria" threads are about MCAT study plans or House of the Dragon, not the enrichment tool.
Due diligence checklist for a Nymeria trial: Verify credit burn rules on your specific plan. Test require behavior against your ICP to measure match rates. Check whether personal-email results skew toward outdated addresses. And confirm the 402/404 distinction so your integration handles failures gracefully.
When Neither Tool Fits
If your bake-off between Kaspr and Nymeria didn't produce a clear winner, Prospeo is worth testing. The database spans 300M+ profiles globally with 143M+ verified emails, a 7-day refresh cycle (the industry average sits around 6 weeks), and a free tier of 75 emails + 100 Chrome credits per month - no card required. Native integrations cover Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make.
That weekly refresh matters most when you're targeting fast-changing roles like SDRs and startup hires. Stale data from tools that don't publish refresh cycles means bounced emails and burned sender reputation - something we've watched teams learn the hard way.
Neither Kaspr nor Nymeria publishes a data refresh cycle - Prospeo refreshes every 7 days. That means fewer bounces, cleaner sender reputation, and contacts that actually pick up. With 30+ filters including buyer intent and technographics, you're not just finding contacts - you're finding the right ones.
Weekly-fresh data beats stale databases every single outbound campaign.
Final Verdict
European sales prospecting with CRM integrations? Kaspr earns its spot. Recruiting with personal email needs and API-first workflows? Nymeria fills that niche.
Here's our hot take: most teams weighing Kaspr vs Nymeria don't actually need either. If your average deal size is under $15k and you're running outbound sequences, you need verified emails at scale and a data refresh cycle that keeps pace with job changes - not a niche regional database or a developer-only API. That points to a different category of tool entirely.
If you're building a broader outbound stack, start with a shortlist of data enrichment services and sales prospecting databases, then map them to your lead generation workflow.
FAQ
Is Nymeria's data accurate?
With only 6 G2 reviews and no independent benchmarks, you're buying with limited third-party signal. The "no email guessing" policy is a strong foundation, but that thin review base is a real procurement risk. Run a trial against your own ICP before committing budget, and compare results against at least one other tool to establish a baseline.
Does Kaspr work outside Europe?
Kaspr's database skews heavily European with 120M+ contacts focused on that region. It has some global coverage, but data quality drops noticeably for North American and APAC prospects. If those regions matter to you, you'll want a tool with 300M+ global profiles.
Is there a free way to test both?
Yes. Kaspr offers 5 phone credits per month free. Nymeria offers 5 enrichment credits per month free, no card required. Both free tiers are too small for a real evaluation - five credits tells you almost nothing about match rates against your actual ICP. Prospeo's free plan (75 emails + 100 Chrome credits/mo, no card) gives you enough volume to run a meaningful test.
