Coldlytics vs Kaspr: Human Research vs Self-Serve Database
Coldlytics and Kaspr look similar on paper, but they're barely competitors. The real question isn't which is better - it's which model fits your workflow. Coldlytics dispatches human researchers to build custom lists on demand. Kaspr is a self-serve Chrome extension backed by a 120M-contact database. One makes you wait. The other limits what you can pull.
30-Second Verdict
Pick Coldlytics if you need bespoke, human-researched lists in English-speaking markets and can wait 24 hours for delivery.
Pick Kaspr if you need instant European phone numbers from a Chrome extension and can live with credit limits.
The Core Difference
Think of it as custom tailor vs department store. Coldlytics dispatches human researchers who pull contacts from Google Maps, professional profiles, Clutch, D&B, and other sources - then validate every email through ZeroBounce before delivering a spreadsheet in under 24 hours. You're paying for research labor and quality control.
Kaspr takes the opposite approach. Its database, checked and verified against 120 sources, sits behind a Chrome extension that surfaces phone numbers and emails instantly while you browse professional profiles. No waiting, no humans in the loop. The tradeoff is you're limited to what's already in the database, and credits gate how much you can pull.
We've seen teams agonize over this comparison when the real deciding factor is simple: do you need data right now, or can you wait a day for something hand-built?

Kaspr - Strengths and Limits
Kaspr is built for fast European contact lookups - especially phone numbers. If that's what you need, it delivers. 699 of its 833 G2 reviews come from European users, and EU phone accuracy runs around 87%. The Chrome extension is genuinely fast; speed is the #1 thing users praise on G2. Paid plans include unlimited B2B email credits plus higher phone and direct email allotments, which is generous for teams doing high-volume European outreach.
Skip Kaspr if:
- You're targeting the US. Phone accuracy drops to roughly 52% stateside - that's a coin flip. We've watched teams waste months trying to make Kaspr work for American prospects before switching tools.
- You need volume. Kaspr Starter gives you 100 phone credits/month with a 12,000 export/year cap. Add-on credits run $0.21-$0.36 each depending on volume. A 5-person team on Business pays ~$395/month on annual billing before add-ons, and credits still run out fast. Credit limitations are the #1 G2 complaint.
- You need CRM-ready lists at scale. Kaspr is built for one-at-a-time lookups, not bulk list building. Business plans cap at 30,000 exports/year.
Let's be honest: Kaspr is the best Chrome extension for European SDRs who prospect one profile at a time. But if your deal sizes are small and you need to blast through hundreds of prospects weekly, the credit model will bleed you dry.
Coldlytics - Strengths and Limits
Customer satisfaction is where Coldlytics earns its perfect G2 score. The Bounce-Free Guarantee refunds credits for any bounced email, and every address runs through ZeroBounce before delivery. An 11-month test across 2M+ emails showed human-researched lists producing up to 3x higher positive response rates than database-sourced contacts. At least one Trustpilot reviewer calls Coldlytics their ZoomInfo replacement, citing fresher data at a fraction of the cost. Trustpilot score sits at 4.8/5 across 57 reviews.
Pricing is straightforward: Free tier gets 25 leads/month, Lite is $49/month for 50 leads, Basic $299/month, Pro $599/month - cost per lead drops to $0.59 on Pro. Credits roll over, which is a nice touch.
Skip Coldlytics if:
- You need data now. The 24-hour turnaround is the fundamental tradeoff. If a rep needs a phone number mid-call, this isn't the tool.
- You're prospecting outside English-speaking markets. Coverage is limited to the US, Canada, UK, Australia, South Africa, and New Zealand.
- You expect a polished UI. G2 reviewers flag the interface as occasionally unintuitive for submitting requests, and some note occasional inaccurate company details - though Coldlytics' support team resolves these quickly.
Neither tool generates much Reddit discussion. Most user feedback lives on G2 and Trustpilot, which is where we pulled the sentiment above.
Why Many Teams Outgrow Both
Here's the thing: most teams reading this comparison want self-serve speed and verified accuracy and global coverage. Neither Coldlytics nor Kaspr delivers all three.
The Chrome extension works across professional profiles, company websites, and CRMs with no credit-gating on B2B emails. Native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Lemlist mean your data flows straight into existing workflows instead of landing in a Google Sheet. And with 30+ search filters including buyer intent data powered by Bombora, you can build targeted lists in minutes rather than waiting 24 hours. Our team tested a 500-contact list build that took under 10 minutes - try that with a 24-hour turnaround or a credit-gated extension.
Free tier: 75 emails and 100 extension credits per month, no annual contracts.
Kaspr charges $0.21-$0.36 per phone credit and caps exports at 30K/year. Prospeo gives you 125M+ verified mobile numbers at ~$0.10 each with a 30% pickup rate - across every region, not just Europe. Data refreshes every 7 days, not whenever a database vendor gets around to it.
Stop rationing credits. Prospect at the scale your pipeline demands.

Can I use Coldlytics and Kaspr together?
