Definition
Email compliance means following the laws and rules that govern commercial email. While specifics differ by region, almost every law rests on the same principles: get permission, make unsubscribing easy, and be honest about who you are.
Under the US CAN-SPAM Act you must include a clear unsubscribe mechanism, honor unsubscribe requests promptly, use truthful subject lines and headers, and identify the message as advertising when required. In Europe, GDPR mandates lawful consent or another legal basis, most commonly explicit consent, plus privacy protections.
Compliance is not optional or future-facing. Violations can bring fines, and spam filters actively penalize senders who ignore permission and opt-out rules. Build consent, transparency and a working unsubscribe into every email from day one.
