About AI Promotional SMS Generator
AI Promotional SMS Generator writes short promotional text messages under 160 characters that drive clicks without feeling like spam. Built for SMS marketing on Klaviyo, Attentive, Postscript, and PIRL, it produces messages that fit the channel's urgency and intimacy — and the strict char limit that comes with it.
Who this tool is for
- Ecommerce brands running SMS marketing on Klaviyo, Attentive, or Postscript
- DTC marketers launching Black Friday, Cyber Monday, and flash-sale campaigns
- Local businesses (restaurants, salons, gyms) sending appointment and promo blasts
- Subscription brands sending reorder reminders and win-back offers via SMS
Real use cases
- Write a Black Friday SMS blast with the offer, deadline, and short link
- Generate a 3-message abandoned cart sequence (1hr, 24hr, 48hr) with escalating urgency
- Write an SMS welcome message for new subscribers after they opt in via popup
- Draft a win-back SMS for customers who have not purchased in 60+ days
- Create a low-stock alert SMS for a product the subscriber browsed but did not buy
How to use AI Promotional SMS Generator
- State the offer clearly: percent off, dollar off, free gift, free shipping, exclusive access
- Specify the audience segment: new subscribers, abandoned cart, VIP, win-back, post-purchase
- Set the urgency: ends tonight, 24 hours, while supplies last, exclusive 48 hours — urgency lifts CTR
- Include the brand name in the first or last 5 chars — SMS arrives without a logo, so brand identity must come from text
- Add the short link placeholder and the STOP-to-opt-out line (required by TCPA in the US and similar laws elsewhere)
Tips for better results
- SMS CTR benchmarks: 9-15% on opted-in audiences (vs 2-3% on email) — but only if the offer is genuinely good and the cadence is restrained
- Cap promo sends to 4-6 per month — over-sending tanks opt-in rate and earns spam reports that hurt deliverability
- Include the brand name in every message — without a sender logo, customers screenshot threads asking "who is texting me"
- A/B test offer language, not message structure — "$10 off" vs "10% off" tells you more than reordering the CTA
Frequently asked questions
Are there legal rules I need to follow for SMS marketing?
Yes — TCPA in the US requires express written consent before sending promotional SMS, plus a clear opt-out (Reply STOP). The EU has GDPR + ePrivacy rules with similar consent requirements. The generator includes opt-out language by default, but you are responsible for the consent capture step.
Why under 160 characters?
160 chars is one SMS segment. Going over splits the message into 2+ segments, which costs more per send and can arrive out of order on some carriers. Some platforms now support 320-char concatenated messages, but 160 still has the best deliverability and read rate.
Can I send the same message to my email list as SMS?
No. Email and SMS need separate opt-ins. Email subscribers have not consented to receive SMS, and sending without consent violates TCPA with $500-$1500 per message fines. Build the SMS list separately via popup, checkout opt-in, or keyword campaigns.
What time should I send promotional SMS?
Most platforms restrict sends to 8am-9pm in the recipient timezone. Best windows are typically 10am-12pm local and 5pm-7pm local — but test against your audience, not benchmarks. Avoid late-night sends entirely; they earn the most spam reports.
