Turn satisfied customers into text subscribers
The gap between "satisfied first-time customer" and "repeat buyer" is often just a communication channel problem. A customer loved your product, but they forgot about you. They don't open your emails. They don't follow you on social. They moved on — not because they disliked the product, but because you have no way to reconnect with them.
Capturing SMS subscribers at checkout and post-purchase closes that gap. You turn a one-time transaction into an ongoing text relationship that drives reorders, repeat purchases, and long-term customer value.

The checkout capture gap
Most ecommerce brands focus on capturing email addresses at checkout — and Shopify makes this easy by requiring an email for order confirmation. But SMS is optional. Unless the brand explicitly adds an SMS opt-in checkbox at checkout, they miss the highest-intent moment to capture a subscriber.
For brands that do add a checkout SMS opt-in, it's often poorly positioned — a generic "subscribe to marketing" checkbox with no clear value prop. The customer checks it (or doesn't), and the brand either gets a low-quality opt-in or misses the opportunity entirely.
Even worse: most brands do nothing to capture customers who check out without opting in. A customer makes a purchase, receives the product, loves it — and the brand has no way to reach them beyond email (which they may never open). That customer who was delighted with their first order simply forgets to reorder because the brand has no mechanism to remind them at the right time.
Checkout and post-purchase SMS capture
With AudienceTap, you capture SMS subscribers at two critical moments: during checkout and after delivery.
At checkout: Add a clear, value-driven SMS opt-in to your Shopify checkout flow — "Get order updates, reorder reminders, and exclusive drops over text." The customer checks the box during the purchase, and they're automatically added to your text list. This works because the customer is already in buying mode and the value proposition is immediately relevant.
Post-purchase: For customers who check out without opting in, include a QR code or text-to-join keyword in the package insert. "Loved your order? Text REORDER to 55444 for early access to new drops and reorder reminders." The customer who just had a great unboxing experience scans the code or texts the keyword while the product is in front of them. Now they're a subscriber — captured at the moment of peak satisfaction.
This two-pronged approach ensures you don't miss anyone. Customers who want SMS updates opt in at checkout. Customers who didn't opt in initially (but loved the product) subscribe after they receive it.
Side-by-side comparison
| Aspect | Traditional | With AudienceTap |
|---|---|---|
| Checkout opt-in | Generic "subscribe to marketing" checkbox | Clear value prop: "Get reorder reminders & exclusive drops via text" |
| Post-purchase capture | None — missed opportunity | Package insert with QR code or keyword |
| Non-subscriber follow-up | Email only (often ignored) | Text-based reorder reminders for opted-in customers |
| Reorder path | Customer has to remember to visit site and reorder | AI-timed reorder prompts via text — one reply to buy |
| Customer lifetime value | Lower — many one-time buyers never return | Higher — text relationship drives repeat purchases |

QR Code to SMS Opt-In
QR Code to SMS Opt-In is a list growth tactic where scanning a QR code pre-populates a text message, allowing customers to opt in to SMS marketing by simply hitting send.
SMS Opt-In / Opt-Out
SMS Opt-In is how consumers give permission to receive business texts. Opt-Out is how they revoke it — typically by replying STOP. Both are required under TCPA regulations.
AI-Timed Replenishment

Growing Your SMS List at Checkout for Non-Subscribers FAQ
Both work. QR codes are faster (one scan and tap), while keywords are easier to remember and don't require a camera. Many brands include both on their inserts.
Thank them for subscribing, acknowledge that they recently received an order, and offer an incentive for their next purchase or sign them up for reorder reminders. Make it immediately valuable.
Shopify allows you to add custom checkout fields and opt-in checkboxes. AudienceTap integrates with Shopify to automatically sync customers who check the SMS opt-in box.
You can customize package inserts based on subscriber status. Customers who already subscribed can receive a different insert (like a referral prompt or product education), while non-subscribers get the SMS opt-in prompt.
