SMS opt-in language: what to put on your forms
Consent is a checkbox and a sentence. Here is the sentence — copy it, adapt the business name, publish it.
The pattern
Valid opt-in is: unchecked box + clear description + link to terms. The recipient must actively tick it (no pre-checked boxes), and the text must say who is texting, what about, roughly how often, and that they can stop.
Copy-paste examples
Checkout / orders:
[ ] Text me order updates from {{business}}. Msg frequency
varies. Msg & data rates may apply. Reply STOP to opt out.Booking forms:
[ ] Send me appointment reminders by text. Reply STOP
to cancel anytime.Contact / quote forms (they expect a reply, so a notice line works):
By submitting, you agree we may text you about your
request. Reply STOP to opt out.Every plan ships these pre-written in the dashboard, matched to your templates.
What happens after the checkbox
We store the consent record (who, when, which form), enforce STOP/HELP automatically, and suppress opted-out numbers so you cannot text them by accident. Quiet hours are enforced on top. Details in compliance behavior.
Common questions
Do I need opt-in to text myself or my staff?
Your own numbers are the simple case — adding them is consent. The checkbox machinery is for customer-facing texts.
Does a phone field on my form count as consent?
No. Collecting a number is not permission to text it — that is the exact pattern that gets numbers filtered and businesses fined. Add the checkbox.
Where does the fine print live?
Link your SMS terms near the checkbox — the pre-written consent language on every plan includes it. See /legal/sms-consent/ for the full policy text.
