Kaspr vs ReachStream: Pricing, Credits & Verdict (2026)

Kaspr vs ReachStream: Which B2B Data Tool Wins in 2026?

Choosing between Kaspr and ReachStream comes down to what you actually need: phone numbers pulled from professional profiles, or high-volume email lists with ABM filtering. Kaspr is a Chrome extension built for grabbing direct dials. ReachStream builds ABM lists across 200M+ profiles with a healthcare focus. They solve different problems, and picking the wrong one means burning budget on credits you can't use - or data that bounces.

30-Second Verdict

Pick Kaspr if you're an EMEA-focused SDR team that lives inside a Chrome extension and needs direct dials. European data coverage is strong - 699 of 833 G2 reviews come from European users.

Pick ReachStream if you need high-volume email lists with ABM filtering, especially in healthcare. The 240,000 email views per year on Polar Peak is generous for the price.

Skip both if email accuracy and data freshness matter most. Kaspr doesn't publish its refresh cadence. ReachStream updates every 45 days. Prospeo refreshes every 7 days with 98% email accuracy across 300M+ profiles - a different league for deliverability-sensitive teams.

Feature Comparison at a Glance

ReachStream's G2 score looks impressive, but 52 reviews vs 833 is a very different confidence interval. Kaspr's rating is battle-tested across a much larger user base.

Pricing and Credit Math

Both tools use credit-based models, but the credits mean very different things.

Kaspr Pricing

Five phone credits on the free plan isn't a trial - it's a tease. You'll burn through those before your first coffee. Even Business caps at 200 phone credits per month, and G2 reviewers consistently flag credit limits as the top frustration. If you want the official breakdown, see Kaspr Pricing.

ReachStream Pricing

Polar Peak at $79/mo billed annually gives you 240,000 email views per year plus unlimited data downloads with the Chrome Extension - far more runway than Kaspr's credit model for email-heavy workflows.

Cost Per Contact

We've run the numbers on both platforms, and the gap is stark:

• Kaspr Business at €99/mo = 200 phone credits = roughly €0.50 per phone number. Need 500 phones a month? You're buying add-on packs and the cost climbs fast.
• ReachStream Polar Peak at $99/mo = 240,000 email views/year = roughly $0.005 per email view. Dramatically cheaper for volume email workflows.

The comparison isn't entirely apples-to-apples since Kaspr's strength is phones and ReachStream's is emails, but if your outbound motion is email-first, the unit economics aren't close.

Data Quality and Freshness

Here's the thing: database size is the most overrated metric in B2B data. A 200M-contact database that refreshes every 45 days will underperform a smaller database refreshed weekly. Stale data kills sender reputation, and sender reputation is the one thing you can't buy back.

If you're evaluating vendors beyond these two, it helps to compare against other sales prospecting databases and data enrichment services so you can separate list size from usable accuracy.

ReachStream updates every 45 days and markets 95% data accuracy and 90% deliverability across 200M+ profiles in 150+ countries. Those are decent numbers. Kaspr is great for point-and-shoot prospecting while you browse professional profiles, but it publishes no refresh commitment for the underlying database.

In our experience with outbound teams, the refresh cadence gap shows up fast in bounce rates. One G2 reviewer put it bluntly: "Phone numbers are outdated and sometimes emails get bounced." That's the cost of infrequent refreshes - and it compounds week over week as contacts change jobs, companies rebrand, and domains go dark. (If you're tracking this closely, use these email bounce rate benchmarks and fixes.)

For teams running weekly campaigns, Prospeo's 7-day refresh cycle is 6x faster than ReachStream's 45-day cadence. We've seen teams switch and watch bounce rates drop from above 5% to under 3% within the first month, which is the difference between ESPs throttling your domain and your sequences actually landing. If deliverability is a priority, follow a full email deliverability guide and tighten your sender reputation process.

Integrations and Reliability

ReachStream offers HubSpot and Salesforce integrations plus webhooks and ReachAPI for custom workflows. The problem? CRM integration issues are a top G2 complaint, with 5 separate mentions in review themes. If you're buying a data tool specifically to feed your CRM, that's a dealbreaker worth testing before you commit. (If you need a checklist, use this guide to connect outreach tool to CRM.)

Kaspr takes a different approach. The extension-first workflow means minimal setup friction, and the Business plan unlocks API access at 60 requests per minute. Integration depth is thinner, but what exists works reliably. For teams that just need data flowing into a CRM without babysitting, Kaspr's simpler architecture is actually an advantage.

Let's be honest - neither tool matches the integration breadth you'd get from platforms like Prospeo, which connects natively to Salesforce, HubSpot, Lemlist, Instantly, Smartlead, Clay, Zapier, and Make. But if you're choosing strictly between these two, Kaspr's reliability edge matters more than ReachStream's feature list.

What Real Users Say

Kaspr earns its 4.4/5 across 833 G2 reviews mostly on Chrome extension speed and European data quality. The dominant complaint is credit limits - seven separate reviews call this out. As one reviewer noted, "Great tool but gets expensive fast once you outgrow Starter." The user base skews heavily European, so if your ICP is North America, coverage thins out noticeably. (For broader stack context, see our ranked list of SDR tools.)

ReachStream scores 4.8/5 across 52 reviews, with data accuracy earning 17 positive mentions and lead generation getting 13. Users praise the list builder and healthcare vertical coverage. Weak spots are integration reliability and gaps in small-business contact coverage. It's strong for reaching upper-level contacts at mid-market and enterprise companies, but if you're prospecting SMBs, expect holes in the data.

The consensus on r/sales threads about B2B data tools generally tracks with what we see here: extension-based tools like Kaspr win on speed, while list-builder platforms like ReachStream win on volume. The real debate is always about data freshness - and neither tool leads that conversation.

Final Recommendation

EU/EMEA SDR team needing phone numbers: Kaspr. The extension workflow is unmatched for quick phone lookups on European contacts. Budget for Business tier minimum - Starter's 100 credits won't last a full week of active prospecting. (If you're building a repeatable motion, these sales prospecting techniques help you get more from limited credits.)

Healthcare targeting + high email volume: ReachStream. The ABM list builder with SIC code filtering and 240K email views per year on Polar Peak is built for this use case. Test the CRM integration thoroughly before committing annual.

Clean deliverability + fresher data: Neither tool solves this well enough. Prospeo covers 300M+ professional profiles with 98% email accuracy, 125M+ verified mobiles with a 30% pickup rate, and a 7-day refresh cycle. The free tier gives you 75 verified emails and 100 Chrome extension credits per month. Paid plans start at roughly $39/mo with no contracts, and it connects natively to every major sales engagement platform.

FAQ

Is Kaspr or ReachStream better for phone numbers?

Kaspr wins for direct dials, especially in Europe - its Chrome extension is purpose-built for pulling phone data from professional profiles. ReachStream's strength is email volume and ABM list building, not phone coverage.

How often does ReachStream update its database?

ReachStream refreshes its master database every 45 days, with a broader three-month monitoring cycle. That's reasonable but not best-in-class for teams running weekly outbound cadences where stale data compounds into bounce rate problems.

Which tool is better for North American contacts?

ReachStream has stronger North American coverage with 200M+ global profiles and SIC code filtering. Kaspr skews heavily European - 84% of its G2 reviewers are based in Europe. For North American outbound with verified emails, Prospeo's 300M+ profile database with 30+ search filters offers the broadest coverage at 98% email accuracy.
