Obligations when sending.
THE CORE PRINCIPLES
Send only to people who agreed to receive Identify yourself clearly Provide a working unsubscribe and honour it promptly Do not use misleading subject lines or sender names
These apply broadly across jurisdictions, with variations.
CONSENT
The safest position is explicit consent: someone actively chose to receive email from you.
A customer who bought something has a relationship with you, and the rules on marketing to them vary.
Buying a list is never acceptable anywhere.
WHAT TO INCLUDE IN EVERY MESSAGE
Your business name A physical address or contact details An unsubscribe link that works
UNSUBSCRIBES
Process them promptly. Continuing to send after someone opts out is the clearest violation and the fastest route to complaints.
Reputable platforms handle this automatically.
DATA PROTECTION
Your list is personal data. Protect it, keep it only while it serves a purpose, and say what you do with it in your privacy notice.
