In today?셲 hyper-connected world, businesses are constantly looking for ways to reach customers directly?봞nd what better way than through their smartphones? Marketing via text messages (SMS) is one of the most effective tools out there. It?셲 fast, direct, and personal. But before you hit “send” on that promotional message, there?셲 something you need to know: marketing texts are subject to legal restrictions.
Yes, there are laws that regulate how, when, and to whom you can send marketing messages. Ignoring them can lead to serious consequences?봣rom customer backlash to hefty fines. Let?셲 break it down.

Why Are There Legal Restrictions?
Text messages are personal. Unlike emails that may end up in a promotions tab or spam folder, SMS messages land directly in a person?셲 inbox?봞nd often with a notification. Because of how intrusive this can be, many countries have consumer protection laws to prevent abuse.
These laws are designed to:
Protect consumer privacy
Prevent spam and fraud
Ensure transparency in marketing

You must have prior express written consent before sending marketing texts
Opt-out instructions are mandatory in every message
Violations can cost up to \$1,500 per message
For European Union countries:
Consent must be freely given, specific, informed, and unambiguous
You must provide a clear and easy way to opt out
You?셱e also required to keep proof of consent
Under the South Korean Act on Promotion of Information and Communications Network Utilization, you must:
