- Addresses collected for another purpose (orders, support tickets) without marketing consent
- Pre-ticked consent boxes or people subscribed 'by default' without consent
Required in every message
- List-Unsubscribe and List-Unsubscribe-Post headers plus a visible unsubscribe link (added automatically)
- A real sender name, a reply-able address and a physical postal address
- A verified (SPF, DKIM, DMARC) sending domain
Prohibited content and behaviour
- Header forgery, misleading From and subject lines
- Phishing, malware, fraud, fake financial offers
