How to Create SMS Quick-Buy Links on Shopify (Skip the Cart, Close the Sale)
SMS marketing has a 98% open rate. You already know this — it's why you're investing in it. But here's the number nobody talks about: SMS conversion rates average 2-3% for most Shopify stores. That means 98 out of 100 people open your text, and 95+ of them don't buy.
The problem isn't your offer. It's what happens after the tap. (For the deep version of this argument, see Checkout Links for SMS.)
A customer gets your text, taps the link, lands on a product page, scrolls, picks a variant, adds to cart, enters a discount code, and then checks out. That's six steps on a phone screen. Every step loses people — and on mobile, the drop-off is brutal.
What if tapping the link went straight to checkout? Product already in the cart. Discount already applied. One tap to buy. That's what a quick-buy link does, and it's the missing piece in most SMS strategies.
Why SMS Conversion Is Broken
SMS platforms are excellent at delivery. The message arrives, the customer reads it, they're interested. Then the link sends them to your product page — and you've lost all the momentum.
Mobile browsing friction. Your product page looks great on desktop. On a phone, it's a scroll-fest. Customers have to find the right variant, read descriptions, swipe through images. They came to buy, not to browse.
Cart abandonment. Even customers who add to cart often don't finish. Shopify's average mobile cart abandonment rate is over 80%. Every screen between "I want this" and "I own this" is a chance to lose the sale.
Discount code fumbling. Your SMS says "Use code FLASH20." The customer taps through, shops, gets to checkout, tries to remember the code, types it wrong, tries again. Some give up.
Context switching. A text message is intimate and immediate. A product page is a marketing experience. The tonal shift kills urgency. By the time they've browsed your page, the impulse is gone.
The fix isn't better product pages. It's fewer pages between the text and the purchase.
How Quick-Buy Links Fix It
A quick-buy link does three things:
- Pre-fills the cart with the exact product and variant
- Auto-applies the discount — no code to remember or type
- Drops the customer at checkout — ready to pay Customer gets your text. Taps the link. Sees checkout with the product and discount already loaded. Enters payment (or uses Shop Pay for one-tap). Done. You've compressed six steps into two: tap and pay.
Setting Up SMS Quick-Buy Links
Step 1: Create the Link in Checkout Links
Open Checkout Links and create a new link. Add the product you're promoting — select the specific variant and quantity so the customer doesn't have to choose. Set a short, clean slug like /sms-flash or /vip-deal.
Pro tip: Use Checkout Links' built-in short links. Every link gets a short URL automatically (e.g., chkl.ink/abc123) that's perfect for SMS where character count matters.
Step 2: Configure the Promotion
In the Promotions card, add your discount. This applies automatically — no code needed. For SMS campaigns, tiered promotions work especially well:
| Cart Value | Discount |
|---|---|
| 1 item | 15% off |
| 2 items | 20% off + free shipping |
| 3+ items | 25% off + free shipping |
SMS audiences are impulse buyers. A tiered discount nudges them to add one more item at checkout, increasing your AOV without a separate upsell flow.
Step 3: Add UTM Parameters
In the Attribution card, tag your link: Source = your SMS platform (postscript, attentive, klaviyo), Medium = sms, Campaign = the specific campaign name. This feeds directly into Shopify Analytics and your CL dashboard.
Step 4: Schedule (If Needed)
Running a time-limited SMS offer? Use the Schedule card to set start and end times. The link activates when your texts go out and deactivates when the offer expires. This is critical for SMS — texts get forwarded, screenshotted, and shared. Without an end time, your "exclusive 2-hour deal" lives forever.
Step 5: Drop It Into Your SMS Campaign
Copy the short link and paste it into your SMS platform. A few examples:
Postscript: FLASH SALE: 25% off our best-seller. Tap to buy (discount applied automatically): chkl.ink/flash25 — Ends tonight.
Attentive: Hey {first_name} - your restock reminder. Same product, same size, one tap: chkl.ink/restock — Reply STOP to opt out.
Klaviyo SMS: VIP early access: New collection drops in 1 hour. Buy now before everyone else: chkl.ink/vip-drop
Notice what these have in common: the link is the CTA. No "visit our store" or "check it out." The link IS the purchase.
Five SMS Campaigns That Convert
1. Flash Sale Blitz. Send a time-limited offer to your full SMS list. The link includes the product, the discount, and a schedule that kills the link when time's up. Urgency is built into the infrastructure, not just the copy.
2. Restock Reminder. Customer bought something 30 days ago. Send a text with a quick-buy link pre-loaded with their previous product. Pair with Checkout Links' dynamic reorder feature and the customer's cart fills automatically.
3. VIP Early Access. Give your SMS subscribers first dibs on a new product. Create the link before launch, schedule it to activate 2 hours before email subscribers get access.
4. Back-in-Stock Alert. Product was sold out, now it's back. SMS is the fastest channel to notify customers. A quick-buy link means they can buy it before it sells out again.
5. Abandoned Cart Recovery. Customer abandoned their cart. Send a text 30 minutes later with a quick-buy link that recreates their cart plus a small incentive.
What to Expect
Merchants using checkout links in SMS campaigns typically see:
- 2-3x higher conversion rates compared to product page links
- Lower cart abandonment — there's no cart to abandon when you skip it
- Higher AOV with tiered promotions that incentivize adding more at checkout
- Better attribution — you know exactly which SMS campaign drove which revenue The math is straightforward. If your SMS list has 5,000 subscribers and you're converting at 2%, that's 100 orders. Move to 5% with quick-buy links and that's 250 orders. Same list, same offer, same copy — just a better link.
SMS Quick-Buy Checklist
Before sending:
- Product added with correct variant/quantity, discount configured and auto-applying
- Short link generated (character count matters in SMS)
- UTM parameters set (source = SMS platform, medium = sms)
- Schedule set if time-limited, message drafted within character limits
- Link tested on mobile (tap it yourself on a phone)
- Compliance language included (STOP to opt out)
Common SMS Link Mistakes
Sending product page links. This is the biggest one. Your SMS platform makes it easy to link to a product. Don't. Link to checkout.
Forgetting mobile testing. You built the link on desktop. Test it on a phone. Tap the link from an actual text message.
No schedule end time. Texts get forwarded. If your "24-hour deal" link works forever, you've trained customers to ignore urgency.
Too many choices. A text message is one thought. One product, one offer, one link. Don't try to promote your entire collection in an SMS.
Why This Matters
SMS is the closest you can get to a customer's attention. A 98% open rate means they're reading your message. The only question is whether you make it easy enough to buy.
Most merchants are wasting that attention by sending customers to product pages — the equivalent of inviting someone to dinner and making them cook. Quick-buy links close the gap between attention and purchase. One tap. Done.
Your SMS list is your most valuable marketing channel. Stop sending it to product pages.
