SMS for business: reminders, alerts and texts people actually read
Text messages get read within minutes, so they’re the best prompt you have — if you respect them. Here’s what SMS is for, the consent rules you can’t skip, and how to write a text people actually act on.
If you want a message read within minutes, text is still the most reliable channel there is. Open rates for SMS run well above 90%, and most texts are read inside three minutes. No other channel comes close. But that power comes with rules: texts are short, they’re personal, and sending them without consent is both rude and legally risky.
What SMS is for
SMS is a prompt, not a document. It works best when the recipient already knows you and is waiting for something concrete:
- Appointment and service reminders — the biggest, most effective use. Confirming a booking or a visit cuts no-shows dramatically.
- Payment and due-date reminders — a short “your payment is due Friday” that nudges an action before a late fee kicks in.
- Status and delivery alerts — order shipped, document sent, application received, technician on the way.
- Time-sensitive notices — appointment openings, urgent follow-ups, confirmations that expire.
Notice what’s missing: long contracts, legal demands, and anything a recipient needs to keep or review carefully. Those belong on email or paper. A text is a tap-on-the-shoulder, not a filing cabinet.
The compliance part you can’t skip
Texting isn’t governed by thinly enforced etiquette — it’s regulated (in the US, chiefly through the TCPA and the wireless-industry CTIA guidelines). The ground rules that keep you safe:
- Get consent before the first text. The person must explicitly opt in to your program. Don’t use a list of numbers you scraped or collected for another purpose.
- One opt-in per campaign. Consent to appointment reminders is not consent to marketing texts. Keep programs separate.
- Always support STOP. Every message must include a clear way to opt out (typically “Reply STOP”), and you must actually honour it, promptly.
- Disclose what they’re signing up for. Be upfront in the signup about frequency and message type. Surprises get you reported, and reports get you suspended.
None of this is optional. Carriers and aggregators enforce it, and consumers expect it — treat texting like a privilege, not a right.
Writing a text people act on
The best business texts are short and give the reader one clear job to do:
- Say who you are — especially on a first text. Include your business name so it isn’t deleted as spam.
- State the action and the deadline. “Your payment is due Friday. Pay here: link.”
- Keep it under ~320 characters where you can. Anything longer belongs in email or on paper.
- Make the CTA a tap away. A payment link, a confirmation button, a “text YES to confirm” — friction kills conversion.
Respect the channel and it overdelivers. Spam the channel and your sender reputation — and your whole program — collapses quickly.
Where SMS fits your correspondence mix
SMS rarely replaces mail or email; it complements them. The pattern that works at most businesses is: text for the prompt (a reminder, a nudge, a confirmation), email for the follow-up (the detail, the link, the summary), and mail for the record (the formal notice, the signed document, the legal requirement).
Compose the underlying message once, and let each recipient get it on the channel that suits the moment — a text for those who need a tap, paper for those who need the file.
