7 Common Mistakes Marketers Make When Building Trade School Contact Lists | EducationDataLists

A strong Trade Schools Email Database should therefore connect each contact to:

Person → Role → Department → Institution → Program area

rather than simply:

Person → Email

3. Assuming a Valid Email Address Means the Record Is Accurate

Email validation is important, but it is only one layer of data quality.

A technically deliverable address can still belong to:

• A former employee
• Someone who changed roles
• A contact at another campus
• A person outside the intended department
• A professional whose responsibilities have changed

This distinction is supported by broader CRM research.

Validity's 2025 State of CRM Data Management report surveyed 602 CRM users and stakeholders and found that 76% said less than half of their organization's CRM data was accurate and complete. Thirty-seven percent reported that poor data quality had caused revenue loss.

These figures are not trade-school-specific, but they demonstrate the scale of the broader B2B data-quality problem.
