How does Cleanlist AI enrich your leads with verified data?
Cleanlist AI takes a sparse lead record (as little as an email address or company domain) and returns the fields the waterfall can resolve: verified email, office and mobile phone numbers, job title, seniority level, company name, industry, employee count and LinkedIn profile URL. There is no revenue, tech-stack or funding-stage field. Running 25+ providers in sequence finds more matches than any one source can.
Why this is hard to do by hand
Leads from webforms, events and bought lists arrive with a name and an email, sometimes less. Before a rep can call, someone has to look up the title, company size and phone number by hand. Do that for 50 leads a day and research eats the week that should go to selling.
Why multi-source lead enrichment changes the win-rate math
28%higher win rate when reps have 10+ data points before first outreach
Forrester's 2025 B2B Sales Benchmark found that deals closed at a 28% higher rate when the seller had 10 or more data points on the prospect before first contact, compared with fewer than 5. More context makes for a sharper opening line and tighter qualification. The hard part is getting to 10 data points, because no single provider covers everyone. In Cleanlist AI's internal testing, one enrichment provider returned 10+ fields for 41% of mid-market B2B leads. A waterfall across 5+ providers returned them for 87%.

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.

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.
14-day Pro trial
250 credits and 3 seats on Pro for 14 days. You don't need a card or a sales call to start.
How it works.
- 01
Send in the leads
Upload a CSV, connect your CRM or send leads through the API. Each record needs one identifier: an email address, a full name plus company, or a LinkedIn URL.
- 02
Pick the fields
Choose contact fields (email, phone, title), company fields (industry, size) or both. You only spend credits on the fields you pick.
- 03
Run the waterfall
Cleanlist AI asks the provider most likely to know the lead first, based on industry and region. If that answer comes back incomplete, the next provider fills the gap, and the run stops at the first deliverable result.
- 04
Normalize the data
Job titles map to a seniority ladder (C-level, VP, Director, Manager, IC), company names match to one canonical form, and phone numbers come back in E.164.
- 05
Confidence per field
Each field gets a High, Medium or Low confidence score based on how many sources agree on it. When providers disagree, the field is flagged for review.
- 06
Send the leads on
Records sync back to your CRM field by field, download as a CSV with your original columns plus the new ones, or come through the API to feed your sequences.
Manual process vs Cleanlist AI.
| Feature | Manual | Cleanlist AI |
|---|---|---|
| Fields enriched per lead | 5-8 (name, title, company, email via LinkedIn search) | Contact, company and firmographic fields, plus AI columns that research other questions per account |
| Cost per lead | 30-45 minutes of a rep's research time | 1 credit per verified work email, 10 per phone number, 0 for a miss |
| Phone number coverage | Rarely found by hand | 85% phone numbers on our 500-lead benchmark |
| Data freshness | A snapshot that goes stale | Re-run enrichment on a schedule to keep records current |
| Seniority classification | A guess from the job title | Titles mapped to one seniority ladder |
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 enrich 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.
What is the minimum information needed to enrich a lead?
One work email is enough. From it, Cleanlist AI returns company data, job title and a phone number where a provider has one. With only a name and company, Cleanlist AI finds and verifies the email first. A LinkedIn URL also works.
How does lead enrichment differ from data append?
Data append adds one missing field, such as a phone number, to a record you have. Lead enrichment fills every field it can, verifies the ones already there, normalizes formatting and adds firmographics, so the rep gets a full profile.
Can I enrich leads in real-time as they come in from webforms?
Yes, through the API, which starts on the Pro plan. Call it from your form handler and each new lead is enriched before it reaches a rep.
