Abandoned checkout SMS is a triggered text message sent to a shopper who started filling out your Shopify checkout — entered their name, email, or shipping details — but did not complete the purchase. It is different from cart abandonment, and it converts significantly better because the purchase intent is higher.
A shopper who adds to cart and leaves is browsing. A shopper who starts entering their address has made a near-decision. That gap matters for how you write the message and what you offer.

Abandoned Checkout vs. Abandoned Cart: The Key Distinction
| Abandoned Cart | Abandoned Checkout | |
|---|---|---|
| Trigger | Added to cart, did not start checkout | Started checkout, did not complete |
| Purchase intent | Moderate | High |
| Common cause | Price comparison, distraction | Unexpected cost, payment friction, second thoughts |
| Conversion rate (SMS) | 14–18% (conversational) | 18–25% |
| Best message angle | Curiosity, product reminder | Friction removal, reassurance |
Checkout abandoners are closer to the finish line. The right message does not need to sell the product — it needs to remove the last friction point.
What Triggers an Abandoned Checkout in Shopify
Shopify counts a checkout as started when a customer provides contact information (email or phone) and moves to the address or payment step. This is distinct from a simple cart — it requires active engagement with the checkout form.
For SMS specifically, you need the customer’s phone number to send a recovery text. This means abandoned checkout SMS is limited to customers who either: – Entered their phone number during checkout – Are existing subscribers on your SMS list whose phone matches their account
Most Shopify SMS apps, including TxtCart, automatically match checkout data with your subscriber list and trigger the flow when the phone number is present.
Setting Up the Flow: Timing and Sequence
Trigger: 15–20 minutes after checkout is started with no completion. Faster than cart recovery because these shoppers are more time-sensitive — they were in the act of buying.
Sequence structure:
Message 1 (15–20 minutes): Friction-removal focused. > Hey [Name] — looks like you didn’t finish your [Brand] order. If something felt off at checkout, just reply and I’ll sort it out. Or pick up where you left off: [checkout link]
Message 2 (2–4 hours, no response): Add a concrete incentive. > Still thinking, [Name]? Your order for [Product] is saved. Here’s 10% off if you complete it in the next 24 hours: [discount checkout link]
Message 3 (24 hours, final): Urgency on the hold. > Last chance, [Name] — your [Product] order is about to expire. Complete it here before we release your items: [checkout link]
Maximum messages: 3. After that, you are generating opt-outs.
What Causes Checkout Abandonment (and How to Address It)
The top checkout abandonment causes in 2026:
1. Unexpected shipping cost (48% of cases) — Address this in Message 1 or 2 by offering free shipping or being transparent about costs
2. Forced account creation — If your store requires account creation at checkout, this is a CRO issue worth fixing separately
3. Payment friction — Card declined, unsupported payment method. Message: “Having trouble at payment? We can help — just reply.”
4. Price second-thoughts — Discount offer in Message 2 handles this directly
5. Distraction / timing — Message 1’s neutral, helpful tone handles this without pressure
Match your message angle to the most likely cause for your store’s customer profile. High-AOV stores ($150+) see more second-thought abandonment; fashion and accessories see more distraction.
Copywriting Rules for Checkout Abandonment SMS
Lead with help, not urgency. Checkout abandoners were in the process of buying. They do not need convincing — they need friction removed. “I can help” outperforms “don’t miss out” for this segment.
Be specific about the product. Name what they were buying, not “your order.” The more specific the message, the higher the click rate.
Keep the link direct. Link back to their actual checkout session, not your homepage or product page. Shopify preserves checkout sessions for 24–72 hours.
Use conversational tone. Unlike broadcast SMS, checkout recovery messages perform best when they feel like a real person checking in. TxtCart’s AI handles every reply in real time — so if a customer responds with a question about shipping or sizing, the conversation continues and the objection gets resolved on the spot.

FAQ
What is the difference between abandoned cart and abandoned checkout SMS?
Abandoned cart SMS triggers when a customer adds a product to their cart but does not start checkout. Abandoned checkout SMS triggers when a customer begins entering their details at checkout but does not complete the purchase. Checkout abandoners have significantly higher purchase intent, and SMS recovery rates are correspondingly higher: 18–25% vs. 14–18% for cart abandonment.
How do I set up an abandoned checkout SMS flow in Shopify?
Most Shopify SMS apps trigger abandoned checkout flows automatically when a subscriber’s phone number is detected in an incomplete checkout session. Set your first message to fire 15–20 minutes after abandonment, include a direct link back to the live checkout session, and configure a second message with an incentive for non-converters at 2–4 hours.
What should an abandoned checkout SMS say?
Lead with friction removal rather than urgency. Acknowledge that they started checkout, offer to help with any issue, and provide a direct link back. For message two, introduce a concrete incentive (free shipping or percentage discount). Keep all messages under 160 characters where possible and use the customer’s name and product name for personalization.
