Clearout vs Kaspr: Different Tools, Different Jobs
Email lists decay by roughly 28% per year That single stat explains why the Clearout vs Kaspr comparison trips up so many teams - one tool fights that decay, and the other doesn't touch it.
Here's what each actually does, where they fall short, and what to use if you need both jobs handled.
30-Second Verdict
Clearout and Kaspr aren't competitors. Clearout is a verification engine - you bring it a list and it tells you which emails are safe to send. Kaspr is a prospecting tool - it extracts contact data from professional profiles, with particular strength in EU markets. Comparing them is like comparing a spell-checker to a word processor.
What Is Clearout?
Clearout is a verification engine with extras bolted on. Its core product takes your email list - CSV, Google Sheets, API - and runs each address through confidence scoring, catch-all resolution, and deliverability-focused checks. You get back a clean list with valid, invalid, and catch-all statuses clearly labeled. Unknown results don't cost credits, which is a nice touch.
Beyond verification, Clearout offers an email finder (4 credits per find), a Chrome extension that works across professional profile surfaces like single pages and search results, and Form Guard for real-time validation at the point of capture. It's GDPR compliant with SOC 2 Type II and ISO certifications. On G2, it holds a 4.6/5 rating across 511 reviews - users consistently praise accuracy and ease of use. Credits run 1 per verification and roll over indefinitely.
What Is Kaspr?
Kaspr is built for one workflow: you're on a professional profile, you see a prospect, you want their phone number and email right now. The Chrome extension pulls contact data from profiles, search results, groups, and events. It's fast, simple (9.2/10 Ease of Use on G2 across 675 responses), and particularly strong for EU contacts.
The database covers 500M+ phone numbers and email addresses, and paid plans include unlimited B2B email credits. Phone numbers are the real currency - you get 100-200 per month depending on your tier, with add-ons running $0.14-$0.16 per credit. One catch: your account needs at least 20 connections to use the tool. With 833 G2 reviews at 4.4/5, it's well-established but narrowly focused. Data quality drops noticeably outside Europe, so teams often pair it with a separate email verification layer.
Two credit systems, two dashboards, one headache. Prospeo replaces both Clearout and Kaspr with 300M+ profiles, 98% verified emails, and 125M+ mobile numbers - all refreshed every 7 days, not 6 weeks.
One platform. One credit pool. Zero bounced emails.
Feature-by-Feature Comparison

| Database size | Not disclosed | 500M+ phone numbers and emails | Kaspr |

| Email finding | 4 credits/email | Unlimited B2B on paid plans | Kaspr |
| Phone numbers | 2 credits/valid or invalid phone | 100-200/mo + add-ons | Kaspr |
| Chrome extension | Profiles + search pages | Profiles, search, groups, events | Kaspr (broader) |
| Form Guard | Yes | No | Clearout |
| Integrations | CRMs/ESPs + Google Sheets | HubSpot, Salesforce, Pipedrive, Zoho, Zapier, dialers | Kaspr |

| G2 rating | 4.6/5 (511 reviews) | 4.4/5 (833 reviews) | Clearout |
| Best for | Teams cleaning existing lists | SDRs prospecting EU contacts | - |
These tools barely overlap. Clearout's verification is rigorous - confidence scores, catch-all handling, the works. Kaspr extracts emails but doesn't deeply verify them. If you're running outbound, Kaspr gets you the contacts and Clearout makes sure they won't bounce. That's two subscriptions, two credit systems, and two dashboards for what should be one workflow.
Pricing Breakdown
| Plan | Kaspr | Clearout |
|---|---|---|
| Free | $0 (15 B2B email + 5 phone + 5 direct email + 10 export credits) | 100 free credits at signup |
| Entry tier | $49/user/mo (annual) | ~$21-$31/mo |
| Mid tier | $79/user/mo (annual) | ~$58-$120/mo |
| Phone add-ons | 250 for $410 | 2 credits/valid or invalid phone |
| Credit rollover | Yes (Starter+) | Yes (never expire) |
Let's do the math that actually matters. A 5-person SDR team on Kaspr Business pays $395/mo base ($79 x 5), which includes 1,000 phone credits (200 per user). Need 250 more? That's another $410. So you're looking at $805/mo for Kaspr alone - and you still haven't verified a single email.
Both tools nickel-and-dime you on credits. Clearout's rollover is genuinely useful, but 24 G2 reviews specifically flag that costs climb fast at volume. We've seen this pattern repeatedly: two separate credit pools drain a budget far faster than teams expect compared to a single platform.
What Users Actually Say
Clearout
Users love the simplicity - ease of use dominates G2 feedback (86 mentions), followed by fast, accurate verification (62 mentions). The interface requires zero training. On the flip side, the credit system feels restrictive for large lists (25 mentions), and bulk verification can slow during peak times. High-volume teams feel the pricing squeeze most.
Kaspr
Dead simple prospecting workflow (14 G2 mentions for ease of use), accurate and updated contact info (10 mentions), and strong Chrome extension integration (6 mentions). Setup takes minutes. The frustrations mirror Clearout's: limited credits deplete fast (7 mentions), phone add-on costs compound quickly (5 mentions), and data completeness gets inconsistent outside Europe.
Here's the thing - both tools share the same core user complaint: credits run out too fast. When two products in different categories trigger the same frustration, that's a signal a single platform would eliminate the problem entirely.
A Simpler Option: Prospecting + Verification in One
We've tested the Clearout-plus-Kaspr stack, and the overhead is real. If you need prospecting depth and verification accuracy without juggling two tools, Prospeo handles both from one dashboard. The database covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobiles, all refreshed on a 7-day cycle (the industry average is 6 weeks). Over 30 search filters - buyer intent powered by Bombora, technographics, job changes, headcount growth - let you build targeted lists fast (more on sales prospecting techniques). Every email goes through 5-step verification with catch-all handling, spam-trap removal, and honeypot filtering before it reaches your CRM.
The Chrome extension (40,000+ users) works on any website or CRM for one-click prospecting. Native integrations cover Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make. Pricing starts free with paid plans at roughly $0.01 per lead - no contracts, no sales calls required. For context, teams like Meritt saw bounce rates drop from 35%+ to under 4% and pipeline triple from $100K to $300K/week after consolidating their data stack.
Kaspr's data thins outside Europe. Clearout can't find contacts. Prospeo does both globally - 30+ filters, 5-step verification, catch-all handling, and spam-trap removal at ~$0.01 per email.
Stop paying twice for what one tool handles better.
FAQ
Can I use Clearout and Kaspr together?
Yes - Kaspr finds contacts and Clearout verifies them. But managing two credit systems, two dashboards, and two invoices adds real friction. Prospeo combines prospecting and verification at ~$0.01/lead, eliminating the dual-tool overhead.
Which tool has better US data?
Clearout works globally for verification, so geography doesn't matter there. Kaspr's prospecting strength is EU-heavy - US phone coverage is noticeably weaker. For US-focused teams, 125M+ verified mobiles with a 30% pickup rate across all regions is a stronger foundation than Kaspr's EU-centric database.
Which has more accurate emails?
Clearout's verification is more rigorous, with confidence scoring and catch-all resolution. Kaspr extracts emails but doesn't deeply verify them. A 5-step verification process achieving 98% email accuracy at the point of extraction removes the need for a second tool entirely.
