Data Cleansing, also known as data cleaning or data scrubbing, is the process of detecting, correcting, or removing inaccurate, incomplete, or irrelevant data from a dataset or database. In B2B marketing and sales, data cleansing is critical for maintaining CRM accuracy, improving lead quality, and enabling better decision-making across all outreach channels.
What Is Data Cleansing?
Data cleansing involves identifying and fixing issues such as:
- ❌ Duplicate records
- 📭 Invalid email addresses or phone numbers
- 🧩 Inconsistent formatting or naming conventions
- 🧓 Outdated job titles, roles, or company information
- 🧼 Empty or missing required fields

The goal is to ensure your data is accurate, actionable, and aligned with your team’s workflows.
