Clearalist vs ContactOut: Verifier or Finder?
You exported 5,000 contacts from your CRM, loaded them into a cold email sequence, and watched 15% bounce rate on the first send. Your sender reputation is bruised. Deliverability is tanking. Now you're searching for a fix - but a Clearalist vs ContactOut comparison doesn't quite make sense, because these two tools do fundamentally different jobs. One verifies emails you already have. The other finds emails you don't.
Let's sort out which one you actually need.
30-Second Verdict
- Need to clean an existing list? Clearalist. Cheap credits, 99% accuracy claim, no subscription required.
- Need to find emails from scratch? ContactOut. 800M+ profiles, Chrome extension - but watch the credit caps closely.
What Is Clearalist?
Clearalist is an email verification service. You upload a CSV, it runs syntax checks, MX record validation, SMTP verification, catch-all detection, and disposable email filtering, then hands you back a cleaned list sorted by status. No prospecting, no contact database - just list hygiene.
The 99% accuracy claim is front and center on their site, and their "Parallel Email Cleaning" method supposedly runs 10x faster than conventional approaches with twice the accuracy. Credits never expire, which is genuinely nice for teams that verify in bursts rather than on a schedule. There's a free 500-email trial to test before buying, plus free deduplication so you aren't burning credits on duplicate rows.
Clearalist has 0 reviews on Serchen. That doesn't invalidate the tool, but it does mean there's almost no third-party feedback to sanity-check the marketing claims.
Here's our take: for small batches, many email sequencers already include basic verification. Clearalist makes the most sense when you're doing real list hygiene at scale - CRM exports, old lists, event lists, that sort of thing.
| Volume | Price | Cost/Email |
|---|---|---|
| 2,500 | $12.50 | $0.005 |
| 10,000 | $40 | $0.004 |
| 50,000 | $150 | $0.003 |
| 100,000 | $250 | $0.0025 |
| 500,000 | $750 | $0.0015 |
What Is ContactOut?
ContactOut is an email and phone finder built around a Chrome extension and search portal. Their coverage sits at 800M+ profiles and 400M+ emails - roughly 150M personal emails, 200M work emails, and 100M direct-dial phone numbers across 40M company profiles.
It integrates with Salesforce, HubSpot, and ATS platforms like Greenhouse and Lever, making it popular with both sales teams and recruiters. G2 rates it 4.4/5 from 109 reviews, with accuracy and ease of use as common praise. Credit limitations and outdated contacts show up as recurring complaints.
In ContactOut's own benchmark across 200 SaaS decision-maker profiles, they hit 90% valid emails, with the strongest results in the US, UK, and Canada. There's also an AI message generator baked in, though that's a nice-to-have rather than a reason to buy.
Look - the "unlimited" email plans aren't really unlimited. Fair-use caps in the terms of service limit you to roughly 2,000 emails/month on the Sales tier and around 1,000 phone numbers/month on the Email+Phone tier. Once you hit the cap, you can't just buy extra credits. You wait for the next cycle or negotiate.
| Plan | Price | What You Get |
|---|---|---|
| Free | $0 | 5 emails/day, 5 phones/day |
| Sales | $79/mo | "Unlimited" emails (~2,000/mo fair-use cap) |
| Email+Phone | $99/mo (annual) | Emails + phones (~2,000 emails/mo + ~1,000 phones/mo), 600 exports/mo |
| Team/API | Custom | API access, dedicated AM |
One more thing worth flagging: there's a Reddit thread where a user was alarmed that ContactOut had their personal phone number and company email - data they believed wasn't publicly available. It reflects the broader tension around how finder tools source and aggregate contact data.
Why pay $83/month across two tools and two workflows? Prospeo finds and verifies emails from 300M+ profiles in a single step - 98% accuracy, 7-day data refresh, ~$0.01 per email. No CSV shuffling between platforms.
Replace your finder and verifier with one platform that does both better.

When to Use Each Tool
Use Clearalist when you already have a list - an old CRM export, a purchased list, contacts from a trade show - and you need to scrub it before loading it into your sequencer. It's cheap, straightforward, and the credits-never-expire model means you aren't locked into a subscription. We've seen teams get the most value from Clearalist when they're doing quarterly hygiene on databases that have been sitting untouched for months.
If you're dealing with deliverability issues beyond list hygiene, pair verification with a broader email deliverability checklist.
Use ContactOut when you're starting from zero and need to build a prospect list. The Chrome extension makes it fast to pull emails while browsing professional profiles, and the search portal works for bulk discovery. Just budget around those fair-use caps, and re-verify anything older than 30 days to protect your sender reputation.
If you need both - finding contacts and then verifying them - you're now paying for two tools and juggling two workflows. That's where the math starts to break down.
The Real Cost of Using Both
Let's run the numbers. Say you find 1,000 emails per month with ContactOut at $79/mo, then verify them through Clearalist at $40 for 10,000 credits - that's roughly $4 for 1,000 verifications. Total: $83/month across two tools, two logins, two exports, and a manual CSV shuffle in between.
The free tier gives you 75 emails and 100 Chrome extension credits per month, enough to test before committing. No contracts, no annual lock-in, no "talk to sales" gate.

In our experience, the single-step find-and-verify workflow cuts list-building time by at least half and eliminates the deliverability risk of stale data slipping through the cracks between two disconnected tools.
ContactOut caps you at ~2,000 emails/month. Clearalist has zero third-party reviews. Prospeo gives you 300M+ verified profiles, 98% email accuracy, and a Chrome extension used by 40,000+ people - with transparent credit pricing and no fair-use surprises.
Get verified emails without the cap games or the guesswork.
FAQ
Does ContactOut really offer unlimited emails?
Not exactly. Paid plans market "unlimited," but fair-use caps limit you to roughly 2,000 emails per month on the Sales plan. Once you hit the cap, you can't buy extra credits - you wait for the next billing cycle or negotiate with their team.
Can I use Clearalist and ContactOut together?
You can. Find emails with ContactOut, then verify them with Clearalist before sending. But at $83+/month for 1,000 contacts across two tools and two workflows, the economics don't hold up against a single platform that handles both steps at ~$0.01/email.
Is Clearalist accurate without third-party reviews?
Clearalist markets 99% verification accuracy, but there isn't much third-party review coverage to validate that number. The 500-email free trial is the fastest way to see how it performs on your specific list.
What if I need both finding and verifying?
That's the exact scenario where a combined platform saves you money and time. Prospeo covers both - 300M+ professional profiles with 98% email accuracy and a 7-day data refresh cycle. The free tier lets you test without a credit card, and paid plans start at roughly $0.01 per verified email.
