🛑 Key Regulations Affecting Email in 2025
📘 1. GDPR (EU)
Still enforces strict rules around personal data in email (names, contact info, behavior tracking).
Consent is required for newsletters and tracking pixels.
Data retention and encryption guidelines apply.
📘 2. EU Digital Services Act (DSA)
Focuses on transparency and accountability for digital communication platforms.
Applies to bulk messaging systems, auto-generated content, and B2B SaaS platforms.
Requires risk mitigation strategies and audit logs for email automation tools.
📘 3. AI Act (Pending Finalization)
Affects tools that use AI to generate, analyze, or personalize emails.
Requires risk classification, explainability, and bias controls.
CIOs must ensure AI email assistants comply with transparency rules.
⚠️ Common Compliance Risks in Business Email
❌ Sending mass emails without opt-in.
❌ Tracking email opens without explicit consent.
❌ Inadequate BCC usage (exposing addresses).
❌ Storing emails indefinitely.
❌ Using AI to draft sensitive messages without human review.
📊 48% of compliance breaches in B2B tech companies in 2024 were email-related (source: Forrester, 2025 Q1 Report).
