How does Cleanlist AI enrich your HubSpot contacts automatically?
Cleanlist AI's native HubSpot integration connects in under 60 seconds via OAuth. From there the waterfall works through 25+ data providers to fill the empty contact properties (email, phone, job title, company size, industry). Results write straight back to HubSpot, so lifecycle stages, lead scoring and workflows run on complete records, with no CSV round trip.
Why this is hard to do by hand
HubSpot properties go stale as people change jobs, companies rebrand and old addresses stop working. HubSpot's data quality tools can flag a bad property, but they can't fill an empty one, so phone numbers, job titles and company revenue still need an outside source. Most enrichment apps for HubSpot pull from one database, and the mid-market and international contacts it doesn't cover stay empty.
Why HubSpot users lose 23% of their contact data every year
23%annual HubSpot contact property decay rate
HubSpot's 2025 State of CRM report found that in the average portal, 23% of contact records have at least one core property (email, phone, company or job title) that is outdated or missing. In a 50,000-contact database that's 11,500 records, each one a possible bounce, failed call or misrouted workflow. Lead scoring, lifecycle automations and email segmentation all read those properties. On a first full-database run, Cleanlist AI customers typically fill 30-40% of the empty phone fields and correct 12-18% of outdated job titles. One HubSpot user with 28,000 contacts got back 6,200 phone numbers in a single run, numbers their previous single-source tool had missed.

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
Connect your HubSpot account
Authorize Cleanlist AI through HubSpot OAuth in one click. There are no API keys to copy. Cleanlist AI maps itself to your contact, company and deal objects.
- 02
Pick the properties to fill
Choose what Cleanlist AI writes: email verification status, phone number, job title, company revenue, employee count and any other property you map.
- 03
Decide which records to run
Run the whole database in one batch, point it at a single static or active list, or turn on enrichment for new contacts as they're created.
- 04
The waterfall runs across 25+ providers
For each contact, Cleanlist AI asks one provider at a time. If the first has no phone number, the next one tries, and the run stops at the first deliverable result. On our 500-lead benchmark that found 98% verified work emails and 85% phone numbers.
- 05
Check the results in HubSpot
The new values sit on the contact record. Cleanlist AI also stamps a 'Last Enriched' date property, which you can use to spot stale records and trigger a re-run.
- 06
Re-run enrichment from HubSpot workflows
Build HubSpot workflows that call Cleanlist AI when a contact reaches a lifecycle stage, joins a list or has a property go stale.
Manual process vs Cleanlist AI.
| Feature | Manual | Cleanlist AI |
|---|---|---|
| HubSpot property coverage | Update fields one contact at a time | Fill empty properties in bulk |
| Data sources queried | 1 enrichment provider (e.g., Clearbit) | 25+ providers, tried in sequence |
| Sync method | CSV export, enrich, re-import | Native HubSpot integration, two-way sync |
| New contact enrichment | Batch runs by hand, weekly or monthly | Runs when a new contact is created |
| Email verification in HubSpot | No built-in verification | Flags invalid, catch-all and disposable addresses |
| What you pay for | A single-source tool license plus rep time | 1 credit per verified email, 10 per phone number, nothing for a miss |
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.
Does the CRM integration work in real-time?
The HubSpot and Salesforce sync runs both ways, so enriched fields write back to the same records. You can run the contacts already in your CRM as one batch, then enrich new ones as they come in.
Does Cleanlist AI write enriched data directly to HubSpot contact properties?
Yes. Cleanlist AI writes enriched data straight to your contact, company and deal properties, standard or custom, depending on how you map them. The values appear on the record in HubSpot, with no CSV export or re-import.
Can I enrich contacts in a specific HubSpot list or lifecycle stage?
Yes. Point a run at an active or static list, or filter by lifecycle stage, lead status or any other property. That lets you spend credits on MQLs or contacts in open deals first.
Will enrichment overwrite existing HubSpot property values?
Not by default. Cleanlist AI fills empty properties and leaves existing values alone. You can change that per field, for example letting job titles update (they change often) while notes and custom properties your reps typed stay untouched.
