Understanding SMS Permission for Compliant Messaging
Getting SMS marketing right starts with a simple principle: permission. SMS permission is the legal and strategic foundation for effective mobile communication. Without it, your marketing can easily cross the line from helpful to intrusive and worse, risk violating GDPR and local privacy laws.
Whether you are sending promotions or updates, SMS permission is what turns a message into something customers want, not something they report. At LINK Mobility, we help businesses collect, manage, and use permission correctly - so you stay compliant and build trust at the same time.
Why SMS Permission Should Not be an Afterthought
SMS is one of the most powerful direct communication channels, with open rates close to 98%. But before you send anything, make sure you have the correct type of SMS permission.
The level of permission needed depends on the type of message and how the relationship with the customer started.
What the GDPR Says About SMS Permission
If your customers are in the EU, you need to follow GDPR rules, which include:
Clear, informed, and specific permission for promotional messages
Transparency on how data will be used
Proof of when and how permission was given
A way for people to unsubscribe easily at any time
LINK Mobility supports you with tools that make collecting and storing permission simple and GDPR-compliant. You get a complete audit trail - and your customers get control.
How to Collect SMS Permission the Right Way
No matter where you collect permission, these three rules always apply:
1. Voluntary
The customer must actively say yes. No pre-checked boxes or hidden clauses.
2. Informed
Let people know what they are signing up for - what kind of messages, how often, and how to opt out.
3. Documented
Keep a record. Whether they signed up via a form, chatbot, or QR code, log the details in your system.
Following these rules builds trust and protects your business legally.
