Clearout vs Prospeo: Verifier or Prospecting Platform?
You've got 5,000 prospects and half the emails will bounce. Or maybe you don't have a list at all - you need to build one from scratch. These two scenarios lead to very different tools, and that's the core tension in the Clearout vs Prospeo decision.
30-Second Verdict
Pick Clearout if you already have email lists and just need cheap, reliable verification at $5 per 1,000 verifications (pay-as-you-go). It's a solid verifier with a loyal user base.
Pick Prospeo if you need to find, verify, and enrich contacts in one workflow - 300M+ profiles, 98% email accuracy, and 125M+ verified mobile numbers inside a single platform.
Skip both if you only need a one-off clean of a tiny list. Clearout gives 100 free credits, and Prospeo includes 75 free emails per month.
The Core Difference
This isn't a close comparison between two similar tools. Clearout is a verification tool that bolted on email finding and prospecting modules. Prospeo is a full prospecting platform with verification built into every workflow.

Think of it like a spell-checker versus a word processor. Clearout checks what you already have. Prospeo builds the document and checks it simultaneously.
The credit structure tells the story. Clearout charges 1 credit to verify an email but 4 credits to find a non-role email - because finding isn't its core DNA. Prospeo charges 1 credit to find and verify in a single action. That difference compounds fast. We've run both workflows side by side, and the credit math is where most teams get surprised.
Pricing Compared
| Dimension | Clearout | Prospeo |
|---|---|---|
| Free tier | 100 free credits | 75 emails + 100 ext. credits/mo |
| Starter | ~$23/mo (3K credits) | $39/mo (1K credits) |
| Mid-tier | ~$58/mo (10K credits) | $99/mo (5K credits) |
| Pro / Business | Enterprise (custom) | $199/mo (20K) / $369/mo (50K) |
| Cost per verification | $0.005 (pay-as-you-go) | ~$0.01 (find + verify) |
| Cost per email found | 4 credits (non-role) / 2 credits (role-based) | 1 credit (verified) |
| Credits expire? | Never | Monthly allocation |

At first glance, Clearout looks cheaper. The math changes when you need to find emails, not just verify them. Clearout's credit structure gets complex fast: 4 credits for a non-role email find, 2 credits for role-based, plus 2 credits per valid/invalid phone number in its Prospect/Reverse Lookup workflows. Prospeo: 1 credit finds and verifies.
The 5,000-email scenario:
| Scenario | Clearout | Prospeo |
|---|---|---|
| Find + verify 5,000 emails | 20,000 finder credits + 5,000 verifier credits | 5,000 credits (all-in) |
| Estimated monthly cost | Depends on plan/top-up rate | $99 (Growth plan) |
Clearout's non-expiring credits are genuinely nice for teams with irregular verification needs. But if you're prospecting monthly, the all-in credit model saves money and eliminates the mental math of "finder credits vs. verification credits."
Here's the thing: if your workflow starts with "I need a list" rather than "I have a list," you're fighting Clearout's credit system instead of using it. The tool was built for verification-first teams, and bending it into a prospecting tool costs more than just picking the right one.

Why juggle finder credits and verifier credits when one platform does both? Prospeo finds, verifies, and enriches contacts in a single workflow - 1 credit per verified email, 98% accuracy, 300M+ profiles with 30+ search filters.
Find 5,000 verified emails for $99. No credit math required.
Accuracy and Data Quality
Hunter's 2026 benchmark tested 15 email verifiers against 3,000 real business emails. Clearout scored 68.37% overall accuracy - second place. The catch: "unknown" results count against the score, so conservative verifiers get penalized. Hunter ran this benchmark and placed first, so take the exact rankings with context. Clearout's own G2 page cites 99.73% accuracy, which is a vendor-reported metric.
About 30% of B2B domains run catch-all configurations, meaning any verifier will struggle with a significant chunk of addresses. On a 5,000-email list, roughly 1,500 addresses will be catch-all - and Clearout charges 1 credit for catch-all results while "unknown" is free.
Prospeo takes a different approach with its 5-step verification process - catch-all handling, spam-trap removal, and honeypot filtering built into every lookup. The 98% email accuracy rate holds across 143M+ verified emails, and the 7-day data refresh cycle means you aren't working with stale records. Clearout doesn't publish a refresh cycle.
Features Head-to-Head
This is where the "verifier vs. platform" gap becomes obvious.

| Feature | Clearout | Prospeo |
|---|---|---|
| Contact database | No searchable database (real-time finding) | 300M+ profiles |
| Verified emails | Real-time verification | 143M+ verified emails |
| Mobile numbers | Phone enrichment (no count published) | 125M+ verified (30% pickup) |
| Intent data | No | 15,000 topics (Bombora) |
| Search filters | Limited | 30+ filters |
| Chrome extension | Yes | Yes (40K+ users) |
| CRM integrations | HubSpot + others via Zapier/Make | Salesforce, HubSpot, Clay + more |
| Data refresh | Not stated | Every 7 days |
| API | Yes | Yes (92% match rate) |
Clearout doesn't offer a searchable contact database where you filter by firmographics and instantly pull a list. Prospeo does exactly that with 30+ filters including buyer intent signals, technographics, job changes, and funding data. Clearout's Salesforce integration is still listed as "upcoming" - Prospeo has Salesforce natively today alongside Smartlead, Instantly, Lemlist, and Clay.
If you need mobile numbers, there's no comparison. 125M+ verified mobiles with a 30% pickup rate is a real asset for any team running cold call sequences. Clearout offers phone enrichment but doesn't publish coverage numbers, which makes it hard to evaluate.
What Users Say
Clearout holds a 4.6/5 on G2 from 510 reviews. Top praise centers on ease of use (86 mentions) and fast, accurate verification (62 mentions). It does what it says on the tin.
The complaints are revealing, though. Credit system restrictions come up in 25 reviews, cost at scale in 24, and bulk verification speed in 18. One r/Emailmarketing thread flagged frustration with paying credits for outcomes that weren't "sendable" - a recurring theme when verification tools hit catch-all domains.
On the Prospeo side, the proof points are workflow-level, not just verification metrics. Snyk dropped bounce rates from 35-40% to under 5% across 50 AEs, generating 200+ new opportunities per month. Stack Optimize built to $1M ARR while maintaining under 3% bounce and zero domain flags across all clients. Those are business outcomes from a platform handling the full prospecting chain, not just a verifier doing one job well.
When to Pick Each Tool
Clearout Is Better When...
You already have lists that need cleaning and verification is your only job. At $5 per 1,000 verifications on pay-as-you-go, it's hard to beat for pure list hygiene. Clearout's HubSpot integration lets you import lists, verify, and push results back - though the "unsubscribe invalid" workflow only works with static lists. If you don't need mobile numbers, intent data, or a searchable database, Clearout is lean and effective.

Skip Clearout if you're planning to use it as a prospecting tool. That's not what it was designed for, and the credit costs reflect that.
Prospeo Is Better When...
You need to build prospect lists from scratch, not just clean existing ones. The combination of finding, verification, and enrichment in one platform eliminates stitching together three separate tools. SDR teams get 300M+ searchable profiles, 125M+ verified mobiles, and intent data to prioritize who to call first - all on self-serve pricing with no contracts. We've seen teams cut their list-building time by 80% just by consolidating into a single workflow instead of juggling a finder, a verifier, and an enrichment tool.

Let's be honest: most teams weighing Clearout vs Prospeo are already outgrowing a verification-only workflow. If that's you, the answer is straightforward.
If you're evaluating broader options beyond these two, start with a business contact database roundup and a comparison of B2B data platforms to sanity-check coverage, refresh, and compliance.

Clearout checks what you already have. Prospeo builds the list you don't. 143M+ verified emails, 125M+ mobile numbers with 30% pickup rate, and intent data across 15,000 topics - all refreshed every 7 days.
Stop cleaning lists. Start building pipelines.
FAQ
Is Clearout or Prospeo more accurate for email verification?
Clearout scored 68.37% in Hunter's 3,000-email benchmark, while Prospeo maintains 98% accuracy across 143M+ verified emails with a 7-day refresh cycle. For pre-verified data quality, Prospeo delivers higher accuracy out of the box.
Can I use both tools together?
Some teams use Prospeo to find contacts and Clearout for a second verification pass. But 98% accuracy with built-in 5-step verification makes this redundant for most workflows - double-verifying rarely catches additional invalids worth the extra cost.
Which tool is cheaper for finding emails?
Clearout charges 4 credits per email found (non-role) plus separate verification credits. Prospeo bundles finding and verification into 1 credit. For 5,000 new contacts monthly, Prospeo's $99 Growth plan covers everything - including mobile numbers and intent data at no extra charge.
