What’s unique about university or government email filters?

University and government email filters often implement stricter policies than commercial providers, reflecting institutional risk aversion and regulatory requirements. These organizations frequently use enterprise solutions (Exchange with EOP, Google Workspace with advanced security) plus additional filtering layers.

Educational institutions may apply content filtering that blocks marketing patterns entirely, regardless of sender reputation. Government filters often include keyword blocking related to security concerns. Both sectors tend toward aggressive blocking when uncertain, preferring false positives over security risks.

Reaching these audiences requires particularly clean sending practices. Avoid marketing language that triggers content filters. Use professional domains rather than free email services for communications. When possible, work with contacts at target institutions to understand their specific filtering environment and whitelist requirements.
