# HubSpot Contact Data Cleanup Process

A repeatable process for cleaning and enriching the HubSpot contact database. Established during a sales standup between Mark Hope and Jacob Jones after identifying that the existing ~40,000-contact database was stale, poorly categorized, and missing key fields like industry.

## Problem

Over time, contacts accumulated from various list imports without consistent enrichment or validation. Key issues identified:

- **Missing industry data** on a large portion of contacts
- **Stale records** — contacts imported years ago with no subsequent activity
- **Unvalidated emails** — high bounce risk on any outreach
- **Miscategorized lifecycle stages** — ~28,000 contacts sitting in "Lead" with insufficient data to qualify or disqualify them

## Cleanup Process

### Step 1 — Export

Export the full contact database from HubSpot. This gives a working dataset outside the CRM for bulk enrichment and validation without risking data integrity in the live system.

### Step 2 — Enrich via Clay

Run the exported contacts through **Clay** to fill in missing fields:

- Industry
- Job title
- Company
- LinkedIn profile
- Phone number

Clay is also used for **email validation on new contacts** before they are ever imported into HubSpot.

### Step 3 — Validate Emails via ZeroBounce

Run the full contact list (especially existing contacts not yet validated) through **ZeroBounce** to:

- Identify invalid, disposable, or high-risk email addresses
- Remove or flag records that would cause bounces
- Protect sender reputation before any outreach campaign

> **Division of tooling:** Clay handles validation for *new* contacts at import time; ZeroBounce handles bulk validation of *existing* contacts during cleanup.

### Step 4 — Reimport with Corrected Data

Reimport the enriched and validated dataset back into HubSpot with:

- Correct industry values populated
- Invalid contacts removed or flagged
- Lifecycle stages updated to reflect actual qualification status (see [[knowledge/hubspot/lifecycle-stage-definitions]])

## Handling the Existing Lead Backlog

The ~28,000 contacts currently in "Lead" status represent a specific cleanup challenge. The goal is to triage each segment:

- **Promote** to MQL or SQL if enrichment reveals sufficient data and qualification signals
- **Remove** if the contact is unvalidatable, irrelevant, or unrecoverable

Leaving 28,000 unqualified leads in the system creates noise and degrades the reliability of any funnel reporting.

## Tooling Summary
