Enrich every HubSpot contact and company, automatically.

Cleanlist AI enriches HubSpot contacts and companies across 25+ providers and writes the results back to your properties. Connect with OAuth, pick a list or your whole database, and skip the CSV exports. When one provider has no match the next one tries, so records come back more complete than a single source leaves them. On our 500-lead benchmark that meant 98% verified work emails and 85% phone numbers.

The HubSpot integration: a contact enriched in Cleanlist AI, with a verified work email, a phone number and a LinkedIn profile, is written into the matching HubSpot record. Empty fields are filled and existing values are kept.

Every field Cleanlist AI writes into HubSpot

Cleanlist AI reads the record, enriches it, and writes the result into HubSpot. Nothing leaves HubSpot permanently, and disconnecting stops future writes without removing what is already there.

What you can do with Cleanlist AI and HubSpot

Cleanlist AI finds and verifies contact data across 25+ providers and writes it into HubSpot.

  1. 01

    Enrich on import

    Import a HubSpot list into Cleanlist AI, enrich it, and sync the verified results back to HubSpot. With live polling on, the list re-syncs every 8 hours.

  2. 02

    Fill the gaps HubSpot leaves

    Find the missing emails and phone numbers, verify the addresses you already have, and standardize titles and company names.

  3. 03

    Score and segment

    Write ICP scores and custom AI columns to HubSpot properties so reps can build segments and prioritize the right accounts.

  4. 04

    Agents on HubSpot triggers

    Start an agent when a deal changes stage or stalls, a record matches your conditions, or someone joins a list. Its CRM Action step can then update the record, set the owner, or add a task or a note.

How it works

Authorize once, choose what to enrich, and the results land in the fields above. HubSpot sync is on Pro and Enterprise, and in the 14-day Pro trial.

  1. Step 01

    Connect HubSpot

    Authorize Cleanlist AI with OAuth, once for the whole workspace. No API keys, no setup call.

  2. Step 02

    Choose what to enrich

    Import a HubSpot list and select the properties you want filled.

  3. Step 03

    Sync back

    Cleanlist AI writes verified data to HubSpot. Turn on the Enrich new CRM contacts agent to fill new contacts as they arrive.

What reaches HubSpot is already verified

Cleanlist AI looks up each record across 25+ providers and checks every address (syntax, domain, mailbox) before it writes anything. Catch-all and risky addresses come through with a flag on them.

98% verified work emails and 85% phone numbers on our 500-lead benchmark.

A demo of Clu, the Cleanlist AI agent, doing this for a whole list. Asked: Clean up HubSpot contacts and verify every email. Fill the missing titles too. Clu runs the tools, asks for confirmation before spending credits (Validate 400 emails and fill empty job titles, 200 credits), fills the list row by row and reports: 400 checked, 61 emails fixed, 88 titles filled and synced back to HubSpot. I didn't touch values you already had.

HubSpot integration FAQ

Setup, overwrites, credits and accuracy.

All integrations
Does Cleanlist read data from HubSpot too?

Yes. Field writes go one way, from Cleanlist AI to HubSpot, and HubSpot records come in through Import from CRM (with live polling every 8 hours), Lookup in CRM, the CRM column in your lists and agent triggers.

Will it overwrite my existing data?

By default Cleanlist AI fills empty properties only. Each mapped field has its own write mode: fill if empty, update if different, always overwrite, or don't sync. A blank value is never written, and records owned by a teammate or tied to an open deal are protected by default.

How are credits used?

Pushing to HubSpot from the web app is free; you spend credits only on the records you enrich. Most teams run a one-time cleanup, then enrich new contacts going forward. HubSpot sync starts on Pro: $89 per seat a month with 1,500 credits per seat. Annual billing takes 25% off.

How accurate is the data Cleanlist AI writes to HubSpot?

Cleanlist AI's 25+ provider waterfall is built to a 98% verified work email and 85% phone number spec, and every address is validated with syntax, DNS/MX, and SMTP checks before it reaches a HubSpot property. Catch-all and risky addresses come through with a flag on them.
