Kaspr vs VoilaNorbert: Honest Comparison (2026)
Most comparison articles for this matchup are thinly veiled product pitches. We checked. So here's a breakdown focused on what each tool actually gives you for your money - and where both fall short.
30-Second Verdict
Kaspr wins if your workflow lives in a browser extension and you need phone numbers alongside emails. The extension is genuinely fast.
VoilaNorbert wins if you already have names and domains and want API-based lookups with pay-per-success billing. It's built for developers and automation-first teams.
Skip both if email accuracy is your top priority. Independent benchmarking flags VoilaNorbert's verified-rate performance as weak, and Kaspr isn't included in the independent benchmarks we found. If deliverability is the deciding factor, you're better off with a tool that has published, benchmarked results.

Pricing Breakdown
Kaspr Plans
| Plan | Annual (per mo) | B2B Email | Direct Email | Phone | Export Credits |
|---|---|---|---|---|---|
| Free | EUR 0 | 15/mo | 5/mo | 5/mo | - |
| Starter | EUR 45 | Unlimited | 5/mo | 100/mo | 1,000/mo |
| Business | EUR 79 | Unlimited | 200/mo | 200/mo | 2,500/mo |
| Enterprise | Custom | Unlimited | Custom | Unlimited | Custom |
Here's the thing about Kaspr's free plan: you get limited monthly credits by default, including 15 B2B email credits, but there's also an invite mechanism that can unlock unlimited B2B emails if you bring three colleagues on board.
Four credit types make Kaspr's pricing harder to evaluate than it should be. "Unlimited B2B emails" on Starter sounds great until you realize those are often generic company addresses - the direct emails you actually want for outreach are capped at 5/month. In our experience, this trips up most new users and creates a frustrating bait-and-switch feeling when you're mid-campaign and suddenly gated.
VoilaNorbert Plans
| Plan | Annual (per mo) | Leads/mo |
|---|---|---|
| Valet | $39 | 1,000 |
| Butler | $79 | 5,000 |
| Advisor | $199 | 15,000 |
| Counselor | $399 | 50,000 |
VoilaNorbert keeps it simple. You pay for successful finds only, credits roll over, and all plans include unlimited team members. Verification is a separate pay-as-you-go product priced at $0.003/email up to 500k, then $0.001/email above that, with a $2 minimum. G2 reviewers note the average time to implement is about one month with ROI typically realized within five months.
If your average deal size is under $5k, neither tool justifies the cost-per-usable-contact math. You need a platform where the vast majority of emails you pull actually land in inboxes - not one where you're paying for data you can't use.
Cost at 1,000 Contacts
Based on the Anymail Finder benchmark (updated September 2025) testing 5,000 contacts, VoilaNorbert's verified rate came in at 36%. That means roughly 360 verified emails from your 1,000 Valet credits at $39/mo - about $0.11 per verified email.

Kaspr Starter at EUR 45/mo gives unlimited B2B emails, but without independent deliverability data on those generic addresses, we can't calculate a fair per-contact cost.

Paying $0.11 per verified email with VoilaNorbert's 36% hit rate - or gambling on Kaspr's unverified generic addresses - doesn't scale. Prospeo delivers 98% email accuracy at $0.01 per email, verified through a 5-step process with catch-all handling and spam-trap removal. No credit-type confusion, no missing domains required.
Stop paying 11x more for emails that don't land.
How Accurate Is Each Tool?
Neither tool topped the Dropcontact benchmark that tested 15 tools across 20,000 real contacts using live sends to measure hard bounces. The best performer hit a 54.9% effective enrichment rate. It wasn't Kaspr or VoilaNorbert.

VoilaNorbert's API page claims "up to 98% success rate," but that 36% verified rate from independent testing tells a different story. VoilaNorbert's pricing page says you only pay for successful finds, yet the Anymail Finder benchmark labels it as "charges for all results" - a discrepancy worth flagging before you commit.
Kaspr checks data against 120+ sources, but we haven't found a neutral third-party benchmark that includes Kaspr in the same kind of verified-rate testing.
A 36% verified rate means nearly two-thirds of your lookups aren't verified. For cold email at any real volume, that kills domain reputation fast. (If you want the mechanics, see our email deliverability breakdown.)
Workflow and Use Cases
When Kaspr Is the Right Pick
You're an extension-first prospector who needs phone numbers for European contacts. Kaspr pulls contact details from professional profiles in your browser, and its coverage leans heavily toward Europe with 120M+ European contacts and built-in GDPR/CCPA alignment.

Skip it if you don't use this kind of browser-based workflow heavily. Kaspr requires a minimum of 20 connections on your account, and the entire product revolves around that extension-led prospecting motion. For teams that work primarily from lists or CRM data, it's a poor fit (especially if you're doing lead generation workflow at scale).

When VoilaNorbert Is the Right Pick
You're building automated workflows and need an API that accepts name + company domain as inputs. VoilaNorbert supports Node.js, PHP, Python, and Ruby, and the pay-per-success model means you're not burning credits on dead ends. (If you're wiring this into outbound, our cold email API guide covers common pitfalls.)
Skip it if you don't have company domains for your prospects. No domain, no lookup. That's a dealbreaker for teams working from messy, incomplete lists where you've only got a name and a company name but no website.
What Real Users Say
Kaspr (4.4/5 on G2) - users praise the ease of use and tight extension workflow. On the flip side, credit limitations frustrate high-volume users, and cost at scale is a recurring complaint.
VoilaNorbert (4.6/5 on G2) - users like the simplicity and accuracy for the contacts it does find. The downsides: missing contacts and limited coverage show up repeatedly in reviews.
We searched Reddit's r/coldemail and other outbound communities for direct comparisons between these two. There are essentially none, which tells you how niche this matchup really is. Most Reddit threads about email finders skip VoilaNorbert entirely and only mention Kaspr in the context of European prospecting.
A Higher-Accuracy Alternative
Pricing runs about $0.01/email with a free tier of 75 emails and 100 Chrome extension credits every month. No contract, no sales call required. For teams that need direct dials too, Prospeo offers 125M+ verified mobile numbers with a 30% pickup rate - well beyond what either Kaspr or VoilaNorbert provides on the phone side.
Let's put the numbers side by side: at 1,000 contacts, VoilaNorbert costs roughly $0.11 per verified email. Prospeo costs about $0.01 per email with a 98% accuracy rate. That's not a marginal difference - it's an order of magnitude. (If you're comparing more options, start with our data enrichment services roundup.)


Need direct dials too? Kaspr caps phone credits at 100-200/month on paid plans. VoilaNorbert doesn't offer phone numbers at all. Prospeo gives you access to 125M+ verified mobile numbers with a 30% pickup rate - plus 300M+ profiles with 30+ filters including buyer intent and technographics.
Emails, mobiles, and intent data in one platform - no credit games.
FAQ
Can I use Kaspr and VoilaNorbert together?
You can - Kaspr for phone numbers via extension, VoilaNorbert for API email lookups. But running two tools doubles cost and complexity. Prospeo covers both emails and mobiles in a single platform at roughly $0.01/email, which simplifies the stack considerably.
Which tool is better for European contacts?
Kaspr has stronger European positioning with 120M+ European contacts and GDPR/CCPA alignment by design. VoilaNorbert doesn't emphasize regional specialization.
Is there a completely free option?
Both free tiers are limited. Kaspr gives 15 B2B email, 5 phone, and 5 direct email credits monthly, with an invite mechanism that can unlock unlimited B2B emails. VoilaNorbert gives 50 one-time credits that don't renew. Prospeo's free plan offers 75 emails plus 100 Chrome extension credits every month - the most generous recurring free tier of the three.
