SMS Compliance Without the Headache
SMS has rules email does not. Get consent, opt-outs, and timing right so you can text your list confidently instead of nervously.
SMS Plays By Different Rules Than Email
Email is forgiving. A bad send costs you an unsubscribe.
SMS is not. Text the wrong person at the wrong time and you are looking at fines, carrier blocks, and a phone number that stops delivering.
That scares a lot of brands into barely texting at all. It should not.
Compliance is not complicated. It is a short list of rules, and once you set them up right, you stop thinking about them and start texting your list with confidence.
The rules below are the practical basics that keep most brands out of trouble. They are not a substitute for legal advice. Confirm the specifics for your business with your SMS provider and your own counsel before you launch.
The Five Rules That Cover You
Get these right and you have handled the parts that matter most.
| Rule | What It Means | Why It Protects You |
|---|---|---|
| Explicit opt-in | The subscriber actively agrees to texts. No pre-checked boxes, no numbers pulled from another form. | Consent is the whole game. Without it, nothing else you do is safe. |
| Clear disclosure | At signup, state that this is marketing texts, that message and data rates apply, and roughly how often you send. | Sets expectations and shows the opt-in was informed. |
| Easy opt-out | Every message tells people they can reply STOP, and STOP removes them instantly. | A person who cannot leave easily is a complaint waiting to happen. |
| Quiet hours | Text during reasonable local times only. Nothing before 8am or after 9pm in the subscriber's time zone. | A 2am text earns a STOP at best and a complaint at worst. |
| Consent records | Keep proof of who opted in, when, and how. | If anyone ever asks, you have the receipt. |
Notice what these have in common. Every one of them is set once and then runs on its own.
Get Consent The Right Way
Consent is where brands get sloppy, and it is the one thing you cannot fake later.
Ask directly. The person types their number into a form built to collect it, or checks a box that clearly says they want texts. A number they gave you for shipping is not consent to market to them.
Disclose at the moment they opt in. Right there at signup, spell out that they are agreeing to marketing texts, that rates apply, and how often you send. Keep it short and plain.
Never buy or import a list. Every number has to have opted in with you. Bought lists are the fastest way to fines and a burned sender reputation.
Here is what a clean opt-in confirmation looks like in practice.
You're in! Reply Y to confirm you want texts from [Brand]. Msg & data rates apply. Reply STOP to opt out anytime.
Make Leaving Easy On Purpose
The instinct is to make opting out hard so you keep more subscribers. Do the opposite.
Every subscriber can reply STOP and be gone instantly. Your platform handles this automatically, so make sure it is on and never override it.
Do not text someone who left. Do not try to win them back on the channel they just walked away from.
An easy exit is not a leak in your list. It is what keeps complaints down, and complaints are what get your number flagged.
Keep Marketing And Transactional Separate
There are two kinds of texts, and the rules treat them differently.
Transactional texts serve the order: shipping updates, delivery notices, order confirmations. People expect these and generally welcome them.
Marketing texts sell: launches, sales, low-stock nudges, back-in-stock alerts. These require the explicit marketing opt-in.
Do not smuggle a promo into a shipping text. Someone who opted into order updates did not necessarily opt into your Friday sale. Keep the two streams clean and you keep your consent airtight.
Common Mistakes
-
Treating a shipping number as a marketing opt-in. A number collected for one purpose is not consent for another. Get a separate, explicit yes for marketing.
-
Pre-checked opt-in boxes. The subscriber has to do the checking. A box that starts checked is not consent.
-
Burying or skipping the STOP. Every message needs a clear way out. Make it obvious, and honor it the second it comes in.
-
Texting across time zones at bad hours. Respect local quiet hours. A late-night text is the fastest path to a complaint.
-
Keeping no records. If you cannot show when and how someone opted in, you cannot prove consent. Log it from day one.
-
Sneaking promos into transactional texts. Keep marketing and order updates on separate consent. Blending them puts both at risk.
