ListClean vs Skrapp: You're Comparing Two Different Tools
Comparing ListClean to Skrapp is like comparing a car wash to a car dealership. One finds emails you don't have. The other cleans emails you already have. The only existing comparison page lumps both into "email verification tools" - which tells you how little thought went into it.
An email finder like Skrapp discovers unknown professional emails from a name, company, or domain. An email verifier like ListClean takes a list you've already built and checks whether each address is actually deliverable. These are sequential steps in a workflow, not competing products. Once you see that, the "which should I pick?" question answers itself.
30-Second Verdict
Need to find emails you don't have? Skrapp. It's a prospecting tool with 200M+ profiles and a Chrome extension for building lists fast.
Need to clean a list you already have? ListClean. Dedicated verification with pay-as-you-go pricing that's hard to beat at scale.
Need both in one step? Prospeo finds and verifies emails from 300M+ profiles with 98% accuracy, starting free.

What Skrapp Actually Does
Skrapp is an email finder first and a verifier second. Its database covers 200M+ professionals across 20M+ companies, and the Chrome extension lets you build lists while browsing professional profiles or company websites. It also offers a REST API for bulk finding and verification. The vendor claims a 92% search success rate and 97%+ verification accuracy, but independent testing paints a different picture.
A practitioner who ran 100,000+ records through ZeroBounce validation found Skrapp's valid email rate at 48% - compared to Apollo's 63%. A separate 2,500-contact benchmark across eight finders put Skrapp at 46% valid. That's not terrible for a finder - discovering any email for a cold prospect has value - but it means roughly half your output needs a second pass through a dedicated verifier.
Skrapp's credit system is fair: you're only charged for Valid or Catch-all results. Pricing starts free at 100 credits/month, jumps to $30/mo for 1,000 credits, and scales to $262/mo for 50,000 credits. Credits roll over and survive cancellation. G2 reviewers praise the ease of use but flag limited credits and outdated data as recurring pain points.
Use Skrapp if you're building prospect lists from scratch and need a fast, affordable finder with a solid Chrome extension. Skip it if you already have a list - you'd be paying finder prices for a verifier workflow.
Skrapp finds emails at ~46% validity. ListClean verifies but can't find. Prospeo does both from 300M+ profiles with 98% accuracy and a 5-step verification process - no CSV exports between tools, no wasted credits on bad data.
Kill the two-tool workflow. Find and verify in one step.
What ListClean Actually Does
$99 for 500,000 verifications. $149 for a million. That's the first thing you need to know about ListClean, because it's the reason teams with large existing lists keep coming back.
ListClean is a pure-play email verifier. Upload a CSV, and it runs each address through live SMTP mailbox checks plus DNS/MX validation, RFC-compliant syntax validation, catch-all handling, disposable email detection, spam-trap detection, hard bounce detection, and role-based email detection. You get back a cleaned file sorted into actionable buckets. Credits never expire, and you aren't charged for Unknown results.
Review scores are strong: 4.7/5 on G2 (135 reviews), 4.8/5 on Capterra (64 reviews), and 4.8/5 on Trustpilot (55 reviews). Multiple Capterra reviewers report bounce rates dropping from ~20% to near zero.
The tradeoffs: integrations are thin, so you'll likely rely on the API or manual CSV exports. And as one Reddit thread on verification accuracy points out, dedicated verifiers can disagree with each other on the same email address - so no single tool's output is gospel.
ListClean is the right call for CRM exports, event leads, or purchased data that needs scrubbing before a campaign. It can't find emails - only clean them.
Pricing at Scale
At 100K emails, ListClean's pay-as-you-go rate works out to roughly $20-30. Skrapp's 50K-credit Enterprise tier runs $262/mo, so 100K credits would cost an estimated $500+/mo - but those credits cover both finding and verifying.
If you already have a list and just need verification, ListClean is 15-20x cheaper per email. If you need to find those emails first, Skrapp's credits cover both steps. The real question isn't which is cheaper - it's which job you're hiring the tool to do.
Here's the thing: if your average deal size is under $5K, you probably can't afford the two-tool workflow at all. The time spent exporting CSVs between a finder and a verifier eats margin fast. We've seen teams burn 15-20 minutes per campaign just shuttling files between tools, and that adds up to hours per week nobody's accounting for.
Skip the Two-Tool Workflow
If you're stitching together a finder and a verifier, Prospeo eliminates that friction. It finds emails from 300M+ professional profiles using proprietary infrastructure and runs every result through a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering - 98% email accuracy out of the box, with data refreshed every 7 days.
At ~$0.01 per email with a free tier of 75 emails/month, it sits between Skrapp's finder pricing and ListClean's verifier pricing but delivers both capabilities in a single step. Fewer tools, fewer CSV exports, fewer bounced emails. One of our customers, Stack Optimize, built to $1M ARR while keeping email deliverability above 94% and bounce rates under 3% - without juggling separate finder and verifier subscriptions.
Stack Optimize built to $1M ARR keeping bounce rates under 3% - no separate finder and verifier subscriptions. At ~$0.01/email with data refreshed every 7 days, Prospeo replaces the Skrapp-to-ListClean pipeline entirely.
One tool. One step. 98% accurate emails out of the box.
FAQ
Can I use Skrapp and ListClean together?
Yes, and many teams do. Find with Skrapp, export, then verify through ListClean before sending. It catches the ~50% of Skrapp results that independent tests show aren't deliverable. It works - it's just not elegant.
Which is cheaper for verification only?
ListClean, by a wide margin. At 100K verifications it costs ~$20-30 versus $500+ through Skrapp's credit system, which is priced for email discovery rather than bulk cleaning.
What about NeverBounce or ZeroBounce?
Both are solid dedicated verifiers in ListClean's category. NeverBounce and ZeroBounce don't replace an email finder, though - so if you need discovery plus verification in one workflow, you'll want a platform that handles both natively rather than bolting two tools together.
