If you're running Klaviyo for a DTC brand and SMS isn't part of your strategy, you're leaving real money on the table. These 10 SMS flows cover the full customer lifecycle, from new subscriber to loyal VIP, and I break down exactly how to trigger and write each one.
TL;DR
- SMS typically generates meaningfully higher engagement rates than email for DTC brands, but most Klaviyo users ignore this channel entirely
- These 10 flows cover the entire customer lifecycle from acquisition through loyalty, each with specific trigger logic and conversion copy frameworks
- Stop paying Zuckerberg premium rates when you already own your existing customer phone list in your Klaviyo account
1. SMS Opt-In Collection at the Point of Purchase
Your checkout page is sitting on a goldmine. Most DTC brands collect emails religiously but leave the phone number field untouched, wasting their highest-converting channel. Deploy a simple SMS keyword like "VIP10" directly at checkout that feeds subscribers straight into your Klaviyo SMS list. You don't need to interrupt the purchase flow or add extra steps. Many brands see meaningful list growth without disrupting conversions. If you want to skip the discount angle, try: "Text VIP10 for early access to new drops." No code required. You're building a list that reaches customers directly, owned, algorithm-free, and separate from your email marketing.
2. Welcome Series: Your First 72 Hours of Ownership
New SMS subscribers are your hottest leads, act fast or lose them. On Day 0, send an instant confirmation text paired with your best offer or a specific product use case that hooks them. Day 1 is for social proof: drop a customer review or user-generated content to reinforce their purchase decision. By Day 3, tackle objections or introduce complementary products. Every message stays concise. This channel works best when it's direct and action-driven, not a story. Each text should move subscribers toward one thing: the next click or purchase.
3. Cart Abandonment: Recover Revenue Klaviyo Email Misses
Email alone leaves most cart revenue unclaimed. Your email sequence fires hours later, too slow. SMS closes that gap. Hit them quickly after abandonment with a time-sensitive message: "Still thinking? Your cart expires in 2 hours." Lead with urgency, not a discount. Include a direct checkout link so they never leave the app. Sync your SMS recovery data with Klaviyo to prevent the same contact getting both an email and a text about the same cart, duplicate outreach tanks conversions. Speed, urgency, one tap to checkout. That's your recovered revenue.
4. Post-Purchase Upsell: The $0 CAC Opportunity
Send an SMS upsell shortly after delivery confirmation, not after purchase, but after your customer opens the box. Someone who just received their order is in active buying mode, and that momentum is your cheapest customer acquisition you'll ever get. Reference what they bought and suggest the perfect complementary product: "Your order included the cleanser, what pairs perfectly? The vitamin C serum." Include a one-click reorder link for consumables. This strategy typically converts at significantly higher rates than cold promotional sends, and since these customers already bought from you, your cost per acquisition on this revenue is essentially zero.
5. Back-in-Stock Alerts: Convert Waitlisted Buyers
When a product comes back in stock, hit your waitlisted customers with an SMS within minutes, not hours. Your strategy should be real-time to capture demand before it diffuses. Segment your waitlist by product SKU so customers only get notified about the exact item they wanted. Lead with specifics: "The [Product Name] in [Color] you wanted is back. Limited units available." One text per restock event, send more and you'll teach them to ignore you. Give these subscribers an exclusive purchase window before your general email blast hits. They've already demonstrated intent. You're just removing the friction between interest and checkout.

6. Win-Back Campaigns: Reactivate Customers Who Buy Once and Disappear
Most DTC brands ignore their customer list after the first purchase, SMS win-back puts those silent contacts back to work. Set up three recency tiers in Klaviyo targeting customers who haven't reordered in different periods. Each segment gets progressively more aggressive: an early tier triggers a soft "we miss you, here's what's new" message, a mid-tier introduces an aggressive incentive to overcome inertia, and your longest dormant tier gets the hardest sell, either a strong offer or a respectful "we're cleaning house, unsubscribe if you've moved on." The urgency at the longest-dormant tier forces action. This channel thrives on recency segmentation because messages hit when customers are primed to recognize the brand again. Your one-time buyers are sitting in Klaviyo right now, start the sequence and watch dormant revenue reactivate.
7. Review & UGC Collection: Build Social Proof on Autopilot
SMS is the highest-converting channel for review requests, text messages get read, email doesn't. Trigger your request after delivery so customers have time to actually use the product. Keep it short: "Loved your recent order? Drop a quick review here [link] and get a meaningful discount on your next one." Same flow, ask for UGC permission: "Mind if we feature your photo? Tag us for a chance to be featured." More reviews and user content mean your retargeting ads convert better, which brings down your cost per acquisition over time. Many brands ignore this flow, yet review and UGC flows are one of the easiest wins sitting right in your Klaviyo account.
8. VIP & Loyalty Rewards: Treat Your Best Customers Like VIPs
Segment your highest-value customers into a dedicated VIP SMS list, these are your brand advocates worth protecting. This approach works best when you treat your best customers differently, not harder. Give them first access to new products before public launches. Send exclusive SMS-only discounts to reinforce their special status. Birthday messages with direct incentives drive high redemption rates because they feel personal. Your VIP customers already engage more than standard buyers, and SMS delivers your message directly to their pocket.
9. Product Launch Countdown: Build Anticipation Before the Drop
This channel becomes essential during product launches because texts cut through inbox clutter in ways email can't. Start well before your drop by driving interested customers to a landing page where they can opt into SMS updates. Then run a tiered countdown sequence: one message builds anticipation early, a later message hits harder with details, another creates final urgency, and launch day converts anticipation into purchases. Track which customers purchase via SMS versus email to close the loop and justify your investment next launch.
10. Flash Sale Alerts: Scarcity-Driven Revenue in Under 2 Hours
Flash sales via SMS let you move inventory fast when urgency feels genuine. The key is unpredictability, running sales on a schedule trains subscribers to wait for discounts, so keep timing random. Keep your message tight and direct: "2-hour flash: 30% off sitewide. Code FLASH30. Ends 8pm. [link]" Don't overdo it, limit flash sales to once a month maximum or you'll train your audience to ignore full-price offers. Always segment by purchase history; never blast flash deals to customers who already pay full price. Done right, a single window via SMS can drive meaningful revenue without eroding your brand.

Frequently Asked Questions
What's the difference between Klaviyo SMS and email flows in terms of ROI?
SMS typically generates meaningfully higher open rates than email because texts are read within minutes, not hours. For DTC brands, SMS flows help recover more abandoned carts than email alone. The key is using each channel for its strength: SMS for urgency and time-sensitive offers, email for storytelling and detailed product education.
How do I get started with SMS in Klaviyo if I'm already running email flows?
Start with three high-impact flows: opt-in collection at checkout, cart abandonment, and post-purchase upsell. These three capture customers at peak purchase intent with zero additional ad spend. Add more flows only after you've optimized these three and have clean data on conversion rates.
What's a realistic SMS list size for a growing Shopify brand?
Many brands at this revenue level work toward a healthy SMS subscriber list within 12 months. Growth rate depends heavily on your opt-in offer and checkout placement of the SMS capture field. Focus on conversion rate rather than raw numbers.

How often should I text my SMS list?
Limit promotional texts to a reasonable frequency per subscriber. Transactional messages (order confirmations, shipping updates) don't count toward this limit. The brands that burn out their SMS lists text too frequently or offer discounts too often, neither creates sustainable revenue.
Do I need separate consent for SMS vs. email in Klaviyo?
Yes. Email consent and SMS consent are tracked separately in Klaviyo. Never assume someone who opted into email wants texts. Build SMS opt-in as a distinct action (keyword, checkbox, landing page) and segment your lists accordingly to stay TCPA compliant.
What's the biggest mistake DTC brands make with SMS marketing?
Treating SMS like email. Brands copy-paste their email strategy into SMS: too frequent, too promotional, too long-winded. This channel works when it's rare, urgent, and action-oriented. If your text message could wait 24 hours, send it as an email instead.
How do I measure SMS campaign success beyond open rates?
Track revenue per message sent, conversion rate by flow, list growth rate, and unsubscribe rate. Klaviyo's built-in attribution shows you which flows drive the most revenue.
