How does Cleanlist AI clean your contact database?
Cleanlist AI's contact cleaning goes beyond removing invalid records. It makes the data consistent across every source: name capitalization, phone formats, company names, and duplicates caught by fuzzy matching. It also removes contacts who are unreachable, unengaged or a compliance risk.
Why this is hard to do by hand
A dirty contact database costs every team something. Marketing mails dead addresses and hurts sender reputation, sales calls numbers that no longer work, and RevOps routes enterprise prospects to SMB reps because the job titles are wrong. The mess builds up over time from dozens of sources, each with its own formatting and its own accuracy.
Inconsistent job titles send leads to the wrong rep
23%of leads are misrouted due to non-standard job titles
Most CRMs route leads on the job title field. B2B job titles are all over the place: 'VP of Sales', 'Vice President, Sales', 'VP Sales & Partnerships', 'Head of Revenue' and 'Chief Revenue Officer' can describe the same seniority and still trigger different routing rules. The rule matches a string, and every vendor, region and company writes that string differently. Title normalization fixes it by mapping every variant to one seniority-and-function grid (VP level, Sales). Customers who fed the normalized titles into their CRM routing saw routing accuracy rise to 94%.

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
Import from every source
Connect your CRM, upload the spreadsheets different teams keep, or bring in several sources at once. Cleanlist AI lines the records up and shows where the same contact appears with conflicting data.
- 02
Score each record
Each record is scored on completeness (fields filled), accuracy (fields that pass validation) and freshness (when the data was last confirmed). A histogram shows how the scores spread across the database.
- 03
Standardize formats
Names get consistent capitals (McDonald, O'Brien and van der Berg included), phone numbers go to E.164, addresses split into structured parts, and job titles map to one hierarchy you can segment on.
- 04
Deduplicate
Fuzzy matching catches duplicates across nicknames (Bob and Robert, Bill and William), company name variants (IBM and International Business Machines) and email domain aliases.
- 05
Validate and enrich
Invalid emails and malformed phone numbers get flagged. If you want, the waterfall fills missing fields, and contacts who changed jobs come back with their new employer.
- 06
Export the clean file
Download the cleaned contacts with every original column plus new quality columns. Suppressed contacts (invalid, duplicate, compliance risk) come in a separate file for your audit trail.

|---|---|---|
| Name standardization | UPPER and lower case mixed together | Capitalization that handles Mc, O' and hyphenated names |
| Cross-source reconciliation | VLOOKUPs between spreadsheets, and the errors that come with them | Matched automatically across CRM, CSVs and imports |
| Nickname resolution | Bob and Robert treated as different people | Bob and Robert matched as one person |
| Cleaning 20K contacts | 2-3 days of spreadsheet work | One automated run that you preview first |
| Ongoing maintenance | A quarterly audit, if someone remembers | Validation at entry, plus monthly re-verification |
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 clean 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 does Cleanlist AI handle contacts that appear in both my CRM and an uploaded spreadsheet?
Cleanlist AI matches them on name, email, company and phone, with fuzzy matching so small differences don't hide a duplicate. The merged record keeps the freshest, most complete value from each source, and you preview every merge before it's applied.
What happens to contacts that fail validation?
They move to a 'Needs Attention' group with the reason attached (bounced email, malformed phone number, company no longer exists). Nothing is deleted. You re-enrich them, archive them or review them one by one.
