Kaspr vs WarpLeads: Credits, Unlimited Exports, or a Third Path?
Your SDR burned through Kaspr's monthly phone credits by Wednesday. They see WarpLeads' $99/mo unlimited pitch and want to switch immediately. Before anyone pulls the trigger, know this: WarpLeads' own help center says roughly 30% of exported emails will be invalid before verification. "Unlimited" needs an asterisk.
30-Second Verdict
| Scenario | Pick |
|---|---|
| European phone numbers, small team | Kaspr |
| Raw volume on a tight budget (verify yourself) | WarpLeads |
Kaspr wins for European phone numbers, but credits run out fast. WarpLeads gives unlimited exports for $99/mo - expect ~30% invalid data and bring your own verification tool. Prospeo covers 300M+ profiles at 98% email accuracy, no post-export cleanup needed.
Why This Comparison Exists
Kaspr users hit two walls: pricing gets steep at volume, and support is slow. When phone credits evaporate mid-week, "unlimited" sounds like freedom. WarpLeads markets exactly that - no caps, flat rate. But the real question isn't "how many leads can I export?" It's whether unlimited unverified data beats limited verified data when your sender reputation is on the line.
Feature-by-Feature Breakdown
| Feature | Kaspr | WarpLeads |
|---|---|---|
| Database size | 120M+ European contacts | 80M+ leads |
| Pricing | Free (15 email + 5 phone credits) / €45 / €79 / Custom | Free (30 contacts + 30 exports/mo) / $99/mo unlimited |
| Model | Credit-based | Flat-rate unlimited exports |
| Email verification | Real-time, built-in | Third-party required (~70% valid after cleaning) |
| Phone numbers | Yes (credit-limited) | Yes (in exports) |
| Chrome extension | Yes | Yes |
| CRM integrations | HubSpot, Salesforce, Pipedrive | CSV export + API (no native CRM sync) |
| API access | Available on paid plans | $299-$999/mo, billed quarterly, requires Unlimited plan |
| Refund policy | Standard SaaS terms | No refunds |
| GDPR | GDPR-focused, EU-first positioning | Compliance messaging |
Kaspr's paid tiers (€45-€79/mo on annual billing) include unlimited B2B email credits, but phone credits cap at 100/month on Starter and 200/month on Business. Enterprise pricing is custom and includes unlimited phone credits. WarpLeads' free plan is genuinely limited - 30 contacts and 30 exports per month - so the real product is the $99/mo tier. Need API access from WarpLeads? Budget $299-$999/mo billed quarterly on top of the Unlimited plan.
Here's the thing: WarpLeads' API pricing makes it a poor fit for any team building automated enrichment workflows. At $299/mo minimum with a quarterly commitment and no refunds, you're paying enterprise prices for data that still needs third-party verification. That math doesn't work.
SDR Workflow Impact
Kaspr verifies contact data in real time, then pushes leads into HubSpot, Salesforce, or Pipedrive. An SDR's workflow is clean: find, verify, push, sequence. If you're standardizing your stack, it's worth mapping this to your broader lead generation workflow.
With WarpLeads, the workflow balloons: export CSV, upload to a verification tool, wait, clean invalid rows, dedupe, import to CRM, then sequence. We've seen teams underestimate this verification workload until deliverability tanks and they're scrambling to warm their domain back up. Budget 30-60 minutes per 1,000 leads for the verify-clean-import cycle, and that's if your process is already dialed in. (If you're building a modern outbound stack, compare options in our guide to SDR tools.)
That 30-60 minute verify-clean-import cycle per 1,000 leads? Prospeo eliminates it. Every email passes 5-step verification before it reaches you - 98% accuracy, no third-party cleanup tool required. Native CRM integrations push verified contacts straight into HubSpot, Salesforce, or your sequencer.
Export clean data the first time - at $0.01 per email.
Data Quality Deep Dive
WarpLeads' own help center states that third-party email verification is "mandatory", with approximately 70% of emails remaining valid after cleaning with a tool like Reoon. For every 1,000 contacts you export, around 300 are dead on arrival. If you're evaluating vendors, this is where data enrichment services and verification differ in practice.
Kaspr takes the opposite approach - real-time validation before delivering a contact. You get fewer leads per month, but they're usable immediately. The tradeoff is clean: WarpLeads gives you volume with a cleanup tax, Kaspr gives you accuracy with a volume ceiling.
The hidden cost of invalid data goes beyond wasted sends. Consistently hitting bad addresses damages your sender reputation with mailbox providers - a problem that takes weeks to recover from and can tank deliverability across your entire domain. Google's Postmaster Tools documentation highlights that high bounce rates are a negative deliverability signal, and once you're flagged, every email you send suffers. Add a verification tool ($30-50/mo) to WarpLeads, factor in the ~30% data loss, and the cost per usable lead tells a different story than the sticker price. For deeper benchmarks and fixes, see our email bounce rate guide and the full email deliverability guide.
Quick math: Export 10,000 WarpLeads contacts at $99/mo + $40/mo verification tool = $139 total. After cleaning, you keep ~7,000 usable emails. Effective cost: ~$0.020 per usable lead. Kaspr at €79/mo gives you unlimited B2B email credits but caps phone credits at 200/month. If you only need emails, Kaspr's per-lead cost is lower - but the moment you need phones at scale, costs jump to custom enterprise pricing.
What Real Users Say
User experiences with WarpLeads vary wildly depending on ICP and how disciplined you are with filtering. If you're pressure-testing list sources, it helps to compare against other sales prospecting databases.
The negative case: One user in r/Emailmarketing called the data quality "terrible" - high bounce rates, outdated emails - even after running contacts through Apollo's verification. That's a red flag for anyone relying on WarpLeads as a primary source.
The positive case: One practitioner ran a 90-day A/B test across six databases with 500 contacts each. WarpLeads hit 9% bounce, 7.1% reply rate, and $22 cost per qualified lead - beating several enterprise-tier tools in that specific test. So results aren't universally bad, but they depend heavily on your list-building discipline and verification stack.
Kaspr's weak spot: Long-time users report that support "takes forever" and costs climb quickly once you need phone numbers at scale. The product works. The business model just squeezes high-volume users.
In our experience, WarpLeads only feels "unlimited" if your filtering and verification workflow is already dialed in. Without that, you're just generating more work for yourself.
When Neither Fully Fits
With 30+ search filters including buyer intent, technographics, and job change signals, you can build targeted lists without the spray-and-pray approach that makes unverified bulk data risky. The Chrome extension (40,000+ users) works on any website or CRM. Native integrations cover Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay, plus Zapier and Make for custom workflows. Self-serve, no contracts, cancel anytime. The free tier gives you 75 emails and 100 Chrome extension credits per month - enough to validate the data quality before committing. (If you're still building your outbound motion, start with these sales prospecting techniques.)
Skip this option if you exclusively need European phone numbers at low volume. Kaspr's EU-first database is genuinely strong there. But for everything else - especially if you've been burned by bad data before - it's worth a test.
Kaspr caps your phones. WarpLeads makes you verify everything yourself. Prospeo gives you 125M+ verified mobile numbers with a 30% pickup rate and 143M+ verified emails - all refreshed every 7 days. No credit ceilings on emails, no post-export cleanup tax.
Get verified emails and direct dials without the tradeoffs.
