Deduplicate Your Contacts Automatically
Deduplicate Your Contacts Automatically: upload a CSV or connect your CRM, and Cleanlist AI checks each row against 25+ providers in sequence. Every new workspace opens on Pro for 14 days with 250 credits, 3 seats.
A Cleanlist AI audit of HubSpot Contacts · 1,284 records. The scan flags a duplicate record, a bounced email, empty title and phone fields and two unformatted or stale titles. Agents merge the duplicate, replace the bounced address with a verified one, fill the empty fields, normalize the titles and write the result back to HubSpot.

How does Cleanlist AI deduplicate your contacts automatically?
Cleanlist AI's deduplication engine uses multi-field fuzzy matching to identify duplicates that exact-match tools miss entirely. It catches name variants (Robert, Rob, Bob), company aliases (IBM and International Business Machines), different email domains (company.com and subsidiary.com) and phone numbers written in different formats. Each matched pair comes with a merge recommendation, and you decide which record survives and which values it keeps.
Why this is hard to do by hand
Duplicate contacts distort your pipeline. When one prospect exists as two records, they can get the same email twice and hit the spam button, turn up in two reps' pipelines and start a territory fight, or split their engagement across both records so the lead score means nothing. Salesforce estimates that 10-30% of records in the average CRM are duplicates.
Duplicates cost sales teams $1,680 per rep per quarter in wasted outreach
$1,680quarterly cost per rep from duplicate-driven wasted outreach
When one prospect exists as several records, the damage spreads through the whole sales process. Cleanlist AI modeled it with data from 65 deduplication projects, where the average CRM had 18% duplicate contact records. The duplicates meant repeat emails to the same prospect, repeat call attempts and pipeline inflated by opportunities counted twice. Reps lost hours calling people a colleague had already spoken to, researching prospects who already existed under another record, and reconciling conflicting entries. At a loaded cost of $120 an hour for a B2B rep, that came to $1,680 per rep per quarter. For a 10-person team, that is more than $67,000 a year, which is more than a CRM cleanup costs.

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
Set the scope
Deduplicate the whole CRM, one list or segment, or a new import before it reaches your database. Cross-object matching works too, such as Leads against Contacts in Salesforce.
- 02
Set matching rules
Pick a sensitivity: Strict (exact name and email), Standard (fuzzy name, same domain) or Aggressive (fuzzy name and company match on any email). Custom rules can weight some fields above others.
- 03
Find the pairs
Cleanlist AI scans the records and returns duplicate pairs or groups, each with a match confidence score. A side-by-side view shows where the records agree, where they conflict and where one has a gap.
- 04
Choose a merge strategy
Four options: Keep Most Complete (the record with the most filled fields survives), Keep Most Recent (the last-modified record wins), Keep Highest Score (for lead-scored databases) or Manual Review (you pick each winner).
- 05
Preview and approve
Every proposed merge shows which value comes from which record before anything changes. Override any field you disagree with.
- 06
Merge and block new duplicates
Apply the approved merges in your CRM or export the clean list. Then turn on duplicate prevention to block new duplicates at the point of entry: form submissions, imports and records created by hand.
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 |
|---|---|---|
| Matching method | Exact match on email only (Excel VLOOKUP) | Fuzzy matching on name, email, company and phone |
| Name variation handling | Bob and Robert count as two people | Nickname mapping plus phonetic similarity |
| Cross-object dedup (Salesforce) | Needs a paid third-party add-on | Lead-to-contact and account-to-account matching built in |
| Deduplicating 50K records | Days of manual review in spreadsheets | One scan, plus a merge preview you approve |
| Future duplicate prevention | None, so duplicates come straight back | Blocked at the point of entry |
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 deduplicate 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 fuzzy matching work and how accurate is it?
Fuzzy matching scores how alike two records are, using edit distance (Levenshtein), Jaro-Winkler similarity and phonetic codes (Soundex, Metaphone), so spelling variants still match. Cleanlist AI adds nickname and company-alias tables on top. How many matches you get depends on the sensitivity you pick, and you preview every merge before it's applied.
What happens to the engagement history on merged records?
It moves to the surviving record. When Cleanlist AI merges two CRM records, the email opens, form submissions, page views and meeting notes on the duplicate carry over, so no history is lost.
Can I deduplicate across multiple CRM objects (e.g., Salesforce Leads vs. Contacts)?
Yes. Cleanlist AI spots when the same person exists as both a Lead and a Contact in Salesforce, which happens a lot after trade shows and webform submissions. It then recommends the conversion or merge that keeps all the associated data.
