Adapt.io vs Clearout: Different Tools, Different Jobs
You pulled 500 contacts from Adapt.io last week, loaded them into your sequencer, and 15% bounced. Now you're searching for "Clearout" to clean the list before your next send. Here's the thing: you're not comparing two competitors. You're weighing a lead database against an email verifier, and that changes how you should decide.
A HubSpot community thread put it well - use an enrichment tool to find contacts, then run them through a validation layer before sending. Adapt.io is the enrichment tool. Clearout is the validation layer. We see this pattern constantly with teams paying for two tools when one platform could handle both jobs.
30-Second Verdict
Most people comparing these two are actually trying to solve two separate problems at once. Here's the shortcut:
- Need new contacts from scratch? Adapt.io.
- Already have a list that needs cleaning? Clearout.
If your average deal size sits below five figures, you probably can't afford the bounce-rate tax of running unverified contacts.
Adapt.io at a Glance
Use this if you need to build prospect lists from zero. Adapt.io positions itself as a lead intelligence platform with 150M+ contacts across 30M+ companies, filterable by job title, department, revenue, location, and more. It earns a 4.6/5 on G2 with 2,789 reviews - solid social proof.
Pricing is credit-based and public: Free ($0/month), Starter ($49/month), and Basic ($99/month), plus a Custom plan for teams that need API access and advanced onboarding. The Free plan includes 25 email credits and 25 enrichment credits per month with daily contact limits, and paid plans scale those credit pools up.
Skip this if email accuracy is non-negotiable for your outreach. The top G2 complaint is limited credits (34 mentions), followed by incorrect email addresses (14 mentions). Regardless of which enrichment database you use, sending unverified emails is how teams rack up bounces and damage sender reputation - which is exactly why that HubSpot thread recommends adding a validation layer before outreach.
The integration ecosystem is also thin. Just 4 integrations on G2 - Salesforce Platform, Microsoft Outlook, Slack, and LinkedIn Sales Insights - compared to tools offering much broader native catalogs.
Clearout at a Glance
Clearout is purpose-built for one thing: scrubbing email lists before you hit send. Bulk uploads, real-time API checks, and a Google Sheets add-on that's genuinely useful for quick cleanups. It holds a 4.6/5 on G2 with 510 reviews, and 80,000+ businesses use it.
The integration count is strong at 29, including HubSpot, Apollo, Lemlist, Zapier, and Make. Credits roll over on subscription plans and never expire - a nice touch for teams with uneven sending volumes.
Pricing runs on credits with monthly, annual, and pay-as-you-go options. A common starting point is $23/month for 3,000 credits and $58/month for 10,000 credits. One detail that catches people off guard: email verification costs 1 credit, but email finding costs 4 credits per lookup.
Clearout markets 99%+ accuracy on its site, but Hunter's benchmark of 15 verifiers across 3,000 real business emails scored Clearout at 68.37% overall accuracy (second behind Hunter at 70.00%). A separate third-party test of 2,500 emails by Sparkle.io returned 88% valid in about 26 minutes.
Skip this if you expect credits back for unverifiable addresses. Reddit users in r/Emailmarketing flag that Clearout consumes credits whether an email comes back "verified" or "not safe to send". Bulk verification can also slow down during peak hours. And while Clearout has added an email finder and prospecting module, those aren't its strength - you're paying a 4x credit premium for finding versus verifying.
Why juggle Adapt.io for sourcing and Clearout for verification when one platform does both? Prospeo's 300M+ profiles come pre-verified through a 5-step process - 98% email accuracy, no export-clean-reupload cycle. At $0.01 per email, it costs less than either tool alone.
Ditch the two-tool tax and start prospecting with verified data from day one.
Side-by-Side Comparison
| Adapt.io | Clearout | Edge | |
|---|---|---|---|
| Primary function | Lead database / enrichment | Email verification | Depends on need |
| Database size | 150M+ contacts | N/A (verifies, doesn't source) | Adapt.io |
| Email accuracy | Flagged (14 G2 complaints) | 68.37% (Hunter benchmark) | Clearout |
| G2 rating | 4.6/5 (2,789 reviews) | 4.6/5 (510 reviews) | Adapt.io (volume) |
| Integrations | 4 | 29 | Clearout |
| Free tier | 25 email + 25 enrichment credits/mo | 100 free credits | Adapt.io (recurring) |
| Paid from | $49/mo | $23/mo | Clearout |
| Credit logic | Separate pools + daily limits | 1 credit = verify; 4 credits = find | Depends on workflow |
These tools are complementary, not competitive. Adapt.io sources contacts. Clearout cleans them. Many teams use both - which means two subscriptions, two credit pools, and two dashboards to manage.
When to Pick Each
Pick Adapt.io when you're building prospect lists from scratch and need company plus contact data in one place. It's particularly strong if your primary market is APAC, where Adapt.io has a reputation as a solid all-rounder. Just plan on pairing it with a separate verification tool before any outreach. The G2 complaints about incorrect emails are too consistent to ignore.
Pick Clearout when you already have lists from events, webinars, or other databases that need cleaning. Its Form Guard feature blocks bad emails at the signup level, which is valuable for marketing teams running lead gen campaigns. For teams whose stack already includes a lead source and just needs the verification layer, Clearout does that job well and affordably.
But if you're paying for both, the math stops making sense pretty fast.
Why We'd Skip the Two-Tool Stack
Adapt.io Starter ($49/mo) plus Clearout Starter ($23/mo) is $72/mo on the low end - and you're still managing two platforms with separate credit pools. In our experience, that friction adds up to more than just dollars; it's the export-import-verify-reupload cycle that kills momentum on outbound campaigns.
If you want to pressure-test alternatives, start with a broader view of data enrichment services and sales prospecting databases before you commit.
Prospeo eliminates that split. Its database covers 300M+ professional profiles with built-in 5-step email verification delivering 98% accuracy. Every contact comes pre-verified, so there's no export-then-clean step. The free tier gives you 75 emails plus 100 Chrome extension credits per month, and paid plans work out to roughly $0.01 per email. With 30+ search filters - including buyer intent powered by Bombora, technographics, and headcount growth signals - it replaces the sourcing side too.
Let's be honest about data freshness, too. Prospeo refreshes records on a 7-day cycle versus the industry average of six weeks, which means fewer stale contacts hitting your sequences in the first place. One of our customers, Snyk, dropped their bounce rate from 35-40% to under 5% after switching - and their AE-sourced pipeline jumped 180%.
If deliverability is the real bottleneck, it’s worth tightening the basics like email deliverability and tracking your email bounce rate alongside any tool change.
Adapt.io's email accuracy issues and Clearout's 68% benchmark score share a root cause: stale data. Prospeo refreshes every record on a 7-day cycle - 6x faster than the industry average - so contacts are verified before they ever reach your sequencer. That's how Snyk cut bounce rates from 35% to under 5%.
Stop verifying bad data. Start with data that's already accurate.
FAQ
Can I use Adapt.io and Clearout together?
Yes, and many teams do - Adapt.io for sourcing, Clearout for cleaning before outreach. It works, but stacking two tools runs $72+/month on paid tiers and adds friction between platforms with separate credit pools and dashboards.
Which tool is better for email accuracy?
Different question for each. Clearout verifies existing emails and scored 68.37% in Hunter's benchmark of 3,000 business emails. Adapt.io provides new contacts but doesn't specialize in verification - G2 reviewers flag incorrect emails as a recurring issue.
Is there a single platform that sources and verifies?
Prospeo combines a 300M+ contact database with built-in email verification at 98% accuracy - one platform, one credit pool, roughly $0.01 per verified email. It removes the need to juggle separate sourcing and cleaning tools.
Does Clearout work for email finding, not just verification?
Clearout has added a prospecting module, but email finding costs 4 credits per lookup versus 1 credit for verification. For dedicated lead sourcing, purpose-built databases offer better value and deeper filtering.
