How this guide was prepared. Last updated October 2026. It draws on Brandmovers' experience designing loyalty programs and member communications. It also draws on the Federal Communications Commission's rules for marketing texts (47 CFR 64.1200) and its consumer guidance, checked at their source. This is general information, not legal advice. |
An SMS loyalty program uses text messages to enroll members, tell them about points, rewards and offers, and prompt them to act, within a broader loyalty program. Because texts reach a personal phone number and autodialed marketing texts require the member's prior express written consent, SMS works best for timely, relevant messages that members have clearly asked to receive.
Text messages are personal: a relevant, well-timed text feels like a service, while an irrelevant or frequent one feels like an intrusion and drives opt-outs. This guide covers when SMS fits a loyalty program, how to collect consent the rules require, how to structure the program, which automated messages to build, how often to send, how to measure results and the rules to follow.

SMS fits a loyalty program when members want timely, short messages, such as reward reminders, expiring points or limited offers, and when the program can personalize them by member.
Texts suit messages that are short, timely and specific to the member: "You have 500 points, enough for a free drink, through Sunday." They suit long content, catalogs or frequent general promotions less well, which email or the program's app handle better. The guide to mobile app engagement for loyalty programs covers push notifications, which follow different permission rules. Whether SMS outperforms email for a given program is something to test, not assume; compare redemption and opt-out rates by channel for the same offer.
Collect SMS consent with a separate, clearly worded opt-in that says members will get marketing texts, is signed electronically, and is not required to join or buy.
Federal rules require "prior express written consent" for autodialed or prerecorded calls that include an advertisement or constitute telemarketing (47 CFR 64.1200), and the rule's revocation provisions refer expressly to "calls or text messages" made under these consent requirements. That consent is a written agreement, signed by the member (an electronic signature counts where federal or state law recognizes it), that clearly authorizes the brand to send advertisements or telemarketing messages, names the phone number they go to, and includes a clear and conspicuous disclosure that the person "is not required to sign the agreement (directly or indirectly), or agree to enter into such an agreement as a condition of purchasing any property, goods, or services." The FCC's consumer guidance summarizes the distinction: "Commercial texts require written consent; for informational texts, your consent may be oral" (FCC).
For a loyalty program, that means:
An opt-in checkbox might read, for illustration only: "Yes, text me offers and reward reminders from [Program] at the number above. Messages are sent by automated technology, up to [X] per month. Consent is not a condition of joining or purchase. Reply STOP to cancel." The wording mirrors the elements the federal definition of written consent requires: authorization of automated marketing messages, the phone number, and a statement that consent is not a condition of purchase.
Whether a particular texting platform counts as an autodialer is a legal question, and state laws can apply their own definitions. Collecting consent that meets the written standard for all marketing texts avoids relying on the answer, and the do-not-call record rules below apply to telemarketing messages whatever system sends them.
Structure an SMS loyalty program around a clear reason to subscribe, such as early access or text-only rewards, a simple opt-in, and benefits that grow as members stay engaged.
Value for subscribing. Give text subscribers something email subscribers do not get, such as early access to sales, text-only rewards or faster bonus offers. Members have more reason to stay subscribed when leaving means giving up value.
Simple sign-up. Extra steps at sign-up can cost subscribers. Keep the opt-in short while meeting the consent requirements above, for example a keyword texted to a short code followed by a confirmation message, or a checkbox on a web form that is not pre-checked. Either route needs the consent disclosures shown before the member opts in, not buried in linked terms. Carrier guidelines also say a recurring program should send a confirmation that includes the program name, customer care contact or HELP instructions, how to opt out, that messages recur and how often, and any fees, and that an opt-in applies only to the campaign it was given for (CTIA).
Progressive benefits. Tier perks, milestone bonuses and text-only offers give members a reason to stay subscribed after the welcome reward.
An SMS loyalty program needs a messaging platform that can segment members, sync reward balances from the loyalty platform, trigger messages from member behavior and record consent and opt-outs.
Segmentation. The platform should send different messages to different members, not one broadcast to everyone.
Balance and activity sync. Messages that mention a member's points, tier or next reward need current data from the loyalty program and purchase history.
Triggers. Messages should fire from member behavior, such as a purchase, a tier change or a period of inactivity, rather than only on a fixed calendar.
Sender setup. Wireless carriers set their own requirements for business texting, separate from federal law, including registering the sending number and describing the program. Confirm these with the messaging provider before launch, and choose between a short code and a standard 10-digit number early, because the choice affects setup time and the opt-in keyword.
Consent and opt-out handling. The platform must record consent, process opt-out replies automatically, including plain-language replies, and honor revocations within the required time. In practice, add the number to a suppression list covering every marketing campaign the consent applied to, not only the one the member replied to.
Number hygiene. Phone numbers change hands. Federal rules give a sender a defense for texting a reassigned number only if it checked the reassigned numbers database, received a response that the number had not been permanently disconnected, and the text resulted from a database error (47 CFR 64.1200).
The most useful automated SMS loyalty messages are a welcome series, reward and balance reminders, tier and milestone notices, birthday rewards and win-back offers, each with one clear action.

Whether a message is marketing depends on its content, not its label: a tier notice that adds "and enjoy 20% off this week" becomes a marketing message. Because the federal definition of telemarketing turns on whether a message is sent "for the purpose of encouraging the purchase" of goods or services, most loyalty texts other than transaction confirmations are safer treated as marketing. Written consent that covers all program texts removes the need to classify each one. Give each message one clear action. The guide to re-engaging dormant loyalty members covers win-back offers in more depth.
There is no universal right frequency; set SMS frequency by member segment, test it against opt-out rates and response, and send within the 8 a.m. to 9 p.m. window.
Frequent buyers may welcome more messages than occasional ones, and the same cadence that works at launch can become tiring as the list matures. Start conservatively, raise frequency for a test group and compare opt-outs, clicks and purchases with a group on the original cadence. For example, split eligible subscribers at random into three groups: one stays on the current cadence, one gets one extra message per month, and one receives no campaign messages as a holdout. After a set period, keep the higher cadence only if its added redemptions and purchases outweigh its added opt-outs.
Federal rules bar telephone solicitations "before the hour of 8 a.m. or after 9 p.m. (local time at the called party's location)," and apply the calling-hours and do-not-call rules to "telephone solicitations or telemarketing calls or text messages to wireless telephone numbers" to the extent the FCC has described (47 CFR 64.1200). The federal definition of a telephone solicitation excludes messages sent with the person's "prior express invitation or permission" or to someone with whom the sender has "an established business relationship," so texts to members who opted in may fall outside it. Keeping marketing texts between 8 a.m. and 9 p.m. in the member's local time is still a sound baseline; use the time zone in the member profile where the program has one, since an area code may not show where the member is. State laws can add their own requirements: Florida's telephone solicitation law, for example, defines a telephonic sales call to include a "text message" and requires prior express written consent for automated ones (Fla. Stat. 501.059).
Measure an SMS loyalty program by clicks, redemptions, opt-outs and purchase behavior, comparing subscribers who received a message with a holdout group that did not.
Open rates are generally not available for SMS, so track clicks, redemptions and opt-out rates per message. For business impact, hold back a random share of eligible subscribers from a promotional campaign (not from reminders members rely on, such as expiring rewards) and compare their purchases and redemptions with those who received it. Comparing SMS subscribers with non-subscribers overstates the effect, because members who opt in to texts are often already the most engaged. Watch opt-out rate by message type and frequency; a rise is a clear sign a message or cadence is wearing thin.
Marketing texts need prior express written consent, members can revoke it by any reasonable method, opt-outs must be recorded and honored, and sends should respect calling hours.
Revocation. Members may revoke consent "by using any reasonable method to clearly express a desire not to receive further calls or text messages." Replies of "stop," "quit," "end," "revoke," "opt out," "cancel," or "unsubscribe" count as a reasonable method on their own, and revocations "must be honored within a reasonable time not to exceed ten business days from receipt of such request" (47 CFR 64.1200). Senders may not require one exclusive way to opt out, and other means of revoking are judged on the totality of the circumstances. A sender may send one confirmation text with no marketing; sent within five minutes, it is presumed to fall within the member's consent. If the member agreed to several kinds of texts, the confirmation may ask which ones the opt-out covers, but texts that need consent must stop until the member clarifies.
Do-not-call records. Anyone sending telemarketing messages must have a written do-not-call policy "available upon demand," train the staff involved, record each request not to be contacted, and honor it for five years (47 CFR 64.1200). These duties apply to telemarketing texts to members who opted in as well.
Calling hours and the national registry. The federal 8 a.m. to 9 p.m. window and the national do-not-call registry rules apply to telephone solicitations, which exclude messages sent with a member's prior express invitation or permission or within an established business relationship. Texts to members who opted in may fall outside them; texts to anyone without that permission do not.
State laws. State telemarketing laws can add requirements, as Florida's does for automated texts. Check them for the states where members live.
Sweepstakes by text. Text-to-enter contests raise separate sweepstakes questions, such as a free method of entry and official rules; the guide to loyalty programs in regulated industries covers sweepstakes rules alongside other category rules.
This is general information, not legal advice.
SMS can be one of a loyalty program's most direct channels when members have asked for it and each message is timely and personal. Keep SMS opt-in separate from program enrollment, collect written consent, honor opt-outs quickly, send within the 8 a.m. to 9 p.m. window, and set frequency by testing rather than by a benchmark. Measure success by redemptions and purchases against a holdout group, not by message volume.
