How does Cleanlist AI verify your contacts are still accurate?
Cleanlist AI's contact verification checks every data point on a contact record: email deliverability, phone number connectivity, job title currency, and company association. That means confirming the person still works at the listed company, in the listed role, and can be reached at the listed email and phone number.
Why this is hard to do by hand
You inherited a CRM built from past reps' contacts, merged databases and old imports. Some of those people have left the company, and some of the phone numbers now ring someone else. Contact data decays every month whether anyone touches it or not, and each call to a dead number or email to a bounced address costs a rep time and a little credibility.
Phone numbers decay 2x faster than email addresses in B2B databases
2xfaster decay rate for phone numbers vs. email addresses
Fields don't all decay at the same rate, and that decides how often you re-enrich. An email address goes stale when someone changes jobs or the company changes domain. A phone number goes stale on its own clock: new company phones, carrier switches, number recycling, and personal mobiles that change with the next carrier deal. Cleanlist AI has not published a field-by-field decay measurement, so treat any single figure with caution and re-verify the fields your motion depends on. If your team cold calls, re-verify phone numbers every quarter, even if emails only get checked every 6 months.
What a lookup costs
Each lookup walks 25+ providers in cost order, and you're charged once for what comes back: 1 credit for a verified work email, 10 for a phone number, 11 for both. Validation is 0.5 and AI qualification is 5. A lookup that finds nothing is free, and the whole team pays from one wallet.

How it works.
- 01
Choose the contacts
Pick CRM lists, segments or the whole database. Filters narrow it to contacts not verified in 90+ days, contacts from imports, or contacts with missing fields.
- 02
Check email deliverability
Each email address gets SMTP verification across more than one provider. Bounced, deactivated and high-risk addresses are flagged, and so are addresses reassigned to someone else, where that can be detected.
- 03
Check phone numbers
Office and mobile numbers are normalized to E.164 and checked against their country's numbering plan, so malformed numbers get flagged. For a contact whose number looks stale, the waterfall can source a current one at 10 credits per phone number.
- 04
Confirm title and company
Cleanlist AI checks the listed title and company against current employment data from several providers. Anyone who has changed role or company is flagged, with the new details attached.
- 05
Verification status
Each contact gets one status: Fully Verified (every field confirmed), Partially Verified (some fields outdated) or Stale (several fields wrong). A summary shows the state of the whole database.
- 06
Update or archive stale contacts
Fully verified contacts are marked current. Partly verified ones can be updated with fresh data automatically. Stale ones you archive, re-enrich or send to someone for manual review.
What you get.
98% verified work emails
That's on our 500-lead benchmark. Cleanlist AI checks each email and flags catch-all and disposable addresses before you send.
25+ data providers
Cleanlist AI asks them one at a time and stops at the first deliverable result. When one provider has nothing, the next one gets its turn.
No code required
Upload a CSV or connect your CRM. If your engineers want it, the API is there from the Pro plan.

Manual process vs Cleanlist AI.
| Feature | Manual | Cleanlist AI |
|---|---|---|
| Verification scope | Email only (if any verification is done) | Email, phone, job title and company |
| Job change detection | You find out when the email bounces or nobody replies | No alerts. A re-run returns the current employer and title |
| Stale phone numbers | Call and find out, on rep time | Format-checked, with a current number re-sourced at 10 credits |
| Database-wide verification (10K contacts) | Weeks of calling and emailing, so nobody does it | One automated batch across every field |
| Verification freshness | A one-off check nobody repeats | Re-verification on a monthly or quarterly schedule |
How accurate is Cleanlist AI's data?
Cleanlist AI returned 98% verified work emails and 85% phone numbers on our 500-lead benchmark, pulling from 25+ data providers. Each lookup stops at the first deliverable result, meaning a verified or likely-valid email.
What do I get when I sign up?
A 14-day Pro trial: 250 credits, 3 seats, and every Pro feature. After it, the Free plan gives you 50 credits a month. A verified work email costs 1 credit, a phone number 10, and a miss nothing.
What data providers does Cleanlist AI use?
Cleanlist AI runs a waterfall across 25+ B2B data providers. For each record it asks one, moves to the next when that one has no match, and stops at the first deliverable result.
Can I connect my CRM?
Yes. HubSpot and Salesforce sync both ways on the Pro and Enterprise plans, and Salesloft and Lemlist take a one-way push. You can also upload a CSV, or use the REST API from Pro.
How long does it take to verify my data?
It depends on the size of the file and how far down the waterfall each row has to go. Cleanlist AI runs the whole CSV as one job, so you upload once and download or sync the results when it's done.
How is contact verification different from email verification?
Email verification asks one question: can this address receive mail? Contact verification checks the whole record: email deliverability, a current phone number, job title and company. It tells you whether the person is still reachable at this company with these details.
What percentage of my contacts are likely to be outdated?
It depends on how old the data is and where it came from. Cleanlist AI's audit gives you the exact breakdown for your own database, record by record, before any credit is spent.
