SMS compliance and loyalty messaging: a primer
Consent, frequency, and opt-out basics for SMS in loyalty—so your nudges help retention without regulatory surprises.
SMS is one of the fastest ways to remind members about points, expirations, and limited perks—but carriers and regulators expect clear consent and easy exits. Loyalty teams should treat SMS as a privilege, not a blast channel.
This primer is educational, not legal advice. Align your flows with counsel for your regions and industries.
Collect consent the right way
Use explicit opt-in language that states you will send loyalty-related messages, who the sender is, and how often you might reach out. Avoid pre-checked boxes for marketing SMS.
Store proof of consent with timestamps. If you import lists from other systems, verify that consent covers loyalty messaging—not only transactional notices.
Honor opt-outs immediately
When someone texts STOP or uses your unsubscribe link, suppress them from promotional SMS right away. Many platforms do this automatically; confirm yours does before scaling sends.
- Separate transactional messages (order updates) from promotional loyalty nudges when policies require it
- Keep message volume reasonable—high frequency erodes trust and increases complaints
- Identify your brand clearly in each message
Fit SMS into your loyalty story
The best loyalty texts are specific: “You are 50 points from a $10 reward” beats generic sales spam. Tie each send to program status and customer benefit.
