HubSpot Data Hygiene
Data hygiene is the ongoing process of keeping your HubSpot database clean, accurate, and useful. Duplicate contacts, stale deals, missing fields, and incorrect properties degrade every system that depends on CRM data: scoring, routing, reporting, outreach, and forecasting. Clean data is the foundation of every GTM operation.
The principle: data hygiene is not a one-time project. It's a recurring process. Data degrades at 2-3% per month through job changes, company merges, email bounces, and human error. A database that's clean today is 25-35% degraded in a year without ongoing maintenance.
The Data Hygiene Framework
Four dimensions of data quality
| Dimension | What it means | How to measure | Example issue |
|---|---|---|---|
| Accuracy | Data is correct and current | Bounce rate, manual spot-check | Email address is wrong, title is outdated |
| Completeness | Required fields are populated | Fill rate per property | Company size is blank on 40% of contacts |
| Consistency | Data follows standards | Dropdown compliance rate | "SaaS", "SAAS", "Software as a Service" for the same value |
| Uniqueness | No duplicate records | Duplicate detection scan | Same person exists 3 times with slight name variations |
