2. Verify people and organizations together

A valid email should be connected to the correct person and current institution.

3. Segment by program

Use career or training specialization to prevent generic messaging across unrelated schools.

4. Add freshness and suppression fields

Track verification dates, role changes, bounces, unsubscribes, and other quality indicators.

5. Audit the database continuously

Do not wait until a campaign produces high bounce or complaint rates. Regular list hygiene is more effective than periodic emergency cleanup.
