How do I ensure my SMS loyalty campaigns with an email and SMS marketing platform are compliant?

To keep SMS loyalty campaigns compliant, make sure you cover these key areas:

1) Get explicit opt-in

• Only text people who have clearly consented to receive SMS.
• Use separate consent for SMS, not a buried checkbox in general terms.
• Store proof of consent: time, date, source, and wording shown at signup.

2) Be transparent at signup

Your opt-in disclosure should explain:

• The brand/business sending messages
• That messages are automated
• Expected message frequency
• Possible message/data rates
• How to opt out
• A link to your SMS terms and privacy policy

3) Always include an easy opt-out

• Every campaign message should include a simple way to unsubscribe, usually:
  • Reply STOP to opt out
• Honor opt-out requests immediately, or as required by local rules.
• Also support common variants like UNSUBSCRIBE, CANCEL, END, and QUIT if your platform allows it.

4) Follow quiet hours and frequency rules

• Send only during allowed hours for the recipient’s timezone.
• Avoid excessive messaging, especially for loyalty programs where users may not expect frequent texts.
• Set internal caps or segment audiences so messages stay relevant.

5) Use compliant content

Avoid misleading, overly aggressive, or prohibited content. Make sure messages:

• Clearly identify your brand
• Match the promise made at opt-in
• Don’t make false urgency or deceptive claims
• Are not promotional if the recipient only consented to transactional messages

6) Respect regional laws

Compliance depends on where your recipients are located. Common frameworks include:

• TCPA in the U.S.
• CTIA guidelines
• GDPR/ePrivacy in the EU/UK
• Local telecom and marketing rules in other countries

If you have international subscribers, segment by country and apply the strictest relevant rules.

7) Separate transactional and promotional messaging

For loyalty programs, distinguish between:

• Transactional: points balance, receipt, account updates
• Promotional: offers, bonuses, limited-time discounts

Make sure the consent matches the message type. Don’t assume transactional consent covers promotions.

8) Maintain records and suppression lists

• Keep audit logs of consent and opt-outs.
• Never re-add unsubscribed numbers unless they re-opt in.
• Suppress invalid, reassigned, or revoked numbers.

9) Work with a platform that supports compliance

Choose an email/SMS platform that offers:

• Double opt-in or verification flows
• Consent tracking
• Automated STOP handling
• Quiet hours
• Regional compliance controls
• Segmentation and suppression management

10) Review your signup and campaign flows regularly

Audit:

• Website forms
• QR code signups
• In-store enrollments
• Keyword-based opt-ins
• Loyalty program enrollment language

Make sure every path collects valid consent and matches your actual messaging practice.
