Launch SMS without a compliance problem
SMS is opened almost immediately, which is its power and its danger, one non-compliant blast can mean fines. AI drafts compliant messages and the setup checklist; you confirm current TCPA/carrier rules and your own consent capture, because the rules are legal, not creative.
First: verify consent and quiet hours
Before a single text goes out, two things must be true. Consent: TCPA requires prior express written consent for marketing texts.
That means an unticked opt-in with the business name, message frequency, "msg & data rates may apply," and opt-out terms all visible at capture (attnagency.com, 2026).
Quiet hours: send only 8:00am-9:00pm in the recipient's local time zone, skip federal holidays, and respect stricter state rules where they apply (attnagency.com, 2026). Confirm both against the current CTIA/TCPA guidance yourself, they change.
Fastest path: one prompt, end to end

You are an SMS marketing specialist launching compliant SMS for a DTC brand.
Brand + product: [one line] Platform: [Klaviyo / Postscript / Attentive]
Messages I want: [welcome, abandoned cart, launch, back-in-stock]
Do this:
1. Open the current TCPA / CTIA messaging guidelines and confirm the 2026 rules for prior express written consent and the 8am-9pm local quiet-hours window (do not rely on memory).
2. Give me a launch compliance checklist: consent language at capture, 10DLC registration, opt-out handling, quiet-hours window, sender ID.
3. Draft 5 SMS (one per message type) UNDER 160 characters each, each ending with opt-out language ("Reply STOP"), no invented discounts, [bracket] placeholders for any real number.
Do not guess any figure: cite the source next to it, and if you can't verify a rule leave it blank and tell me which guideline to check.
Output: checklist + 5 messages.
Launch it in Klaviyo/Postscript (compliance checklist)
- Consent at capture. Turn on the SMS opt-in on your form with the required disclosure text; don't pre-tick it. No consent, no send.
- Register 10DLC. Complete brand + campaign registration in your platform before sending; unregistered A2P traffic gets filtered or blocked by carriers.
- Set quiet hours to 8am-9pm by recipient time zone. Klaviyo/Postscript schedule by local time, switch it on so a night send doesn't fire at 2am.
- Confirm STOP is automatic. Every message ends with "Reply STOP"; the platform honors opt-outs instantly, verify it's enabled.
- Keep it rare and time-sensitive (launches, back-in-stock, cart recovery, order updates), not daily blasts. Done = a test number receives a compliant message only inside the quiet-hours window.
Worked example (cost-per-send vs revenue): cost side, at ~$0.01 per segment a 1-segment launch to 5,000 subscribers = ~$50. Revenue side, if it drives 40 orders at $70 AOV and 55% margin = 40 x $70 x 0.55 = $1,540 gross. Net ~$1,490.
SMS pays easily when it's rare and relevant, plug your platform's real per-segment rate into the cost side.
