Consent rules vary by jurisdiction and by the kind of communication being sent, so this page is not legal advice. The practical design principle is simpler: do not hide a marketing relationship inside the act of requesting internet access.
Practical checklist
- Make access terms and marketing permission understandable.
- Do not pre-check optional marketing boxes where that would be inappropriate.
- Record what a person agreed to and when.
- Make unsubscribe and preference controls easy to find.
- Review SMS, email and privacy requirements for the jurisdictions you serve.
Important: Have qualified counsel review your implementation when regulatory compliance is material to the business.
