An SMS drip campaign is a pre-written sequence of text messages delivered on a scheduled cadence after a subscriber takes a specific action, like joining your list, making a first purchase, or signing up for a waitlist. Each message in the drip fires at a set interval after the trigger, regardless of what else the subscriber has done.
This is different from triggered flows, which respond to real-time behavior. A drip runs on a clock. A triggered flow runs on a signal. Both have their place in a complete SMS strategy.

SMS Drip vs. Triggered Flows: When to Use Each
| SMS Drip Campaign | Triggered SMS Flow | |
|---|---|---|
| What fires it | Time elapsed since trigger | Specific customer behavior |
| Message timing | Fixed intervals (Day 1, Day 3, Day 7) | Dynamic (15 min after abandon, etc.) |
| Best use case | Onboarding, nurture, re-engagement | Cart recovery, browse abandon, post-purchase |
| Personalization | Name, segment, purchase history | Real-time cart content, product viewed |
| Opt-out sensitivity | Medium | Lower (contextually relevant) |
Both formats belong in your SMS program. Drips build the relationship. Triggered flows close the sale.
The 4 SMS Drip Campaigns Every Shopify Store Should Have
1. Welcome Drip (Post-Opt-in)
Your highest-engagement window is the 7 days after a subscriber joins your list. A three-message welcome drip maximizes that window.
Day 0 (Immediate): Deliver the opt-in incentive + set expectations. > Welcome to [Brand] texts, [Name]! Here’s your 10% off: WELCOME10 at checkout: [link]. Expect early access to drops, deals, and restock alerts — reply STOP to opt out anytime.
Day 2: Brand story + social proof. > Hey [Name] — a little about us: [2-sentence brand story]. 4,700+ happy customers and counting. Here’s what they’re saying: [review link]
Day 5: Product recommendation or bestseller highlight. > [Name] — if you haven’t tried [Best Seller], now’s the time. It’s our most reordered product for a reason: [link]
The welcome drip is where most stores leave money on the table. The opt-in gets a single confirmation text and then silence. A three-message sequence converts 15–20% more subscribers into first-time buyers compared to a single welcome message.
P.S. TxtCart’s welcome flow setup takes under 10 minutes — you write the messages, TxtCart handles timing, personalization, and delivery. Any replies from subscribers during your welcome drip get handled by TxtCart’s AI in real time.
2. Post-Purchase Nurture Drip (First-Time Buyers)
Converting a one-time buyer into a repeat customer is 5x less expensive than acquiring a new one. This drip starts the moment an order is placed.
Day 1: Order confirmation + shipping update. > Your [Brand] order is confirmed, [Name]! We’ll text you when it ships. In the meantime, check out what customers are pairing with your [Product]: [link]
Day 7 (after estimated delivery): Experience check-in. > Hey [Name] — how’s your [Product] treating you? Let us know if you have any questions. We’re here: just reply.
Day 14: Review request. > [Name] — hope you’re loving your [Product]. We’d genuinely appreciate a quick review if you have 60 seconds: [review link]. It helps other customers a lot.
Day 30: Second purchase incentive. > [Name] — it’s been a month since your first [Brand] order. We wanted to say thanks with 15% off your next one: USE15 [link]
This four-message sequence runs automatically for every new customer without any manual intervention. Brands running this drip see second-purchase rates 20–30% higher than stores with no post-purchase SMS follow-up.

3. Winback Drip (Lapsed Customers)
Target customers who purchased 90–120 days ago and have not returned. Two to three messages with escalating offers.
Message 1 (Day 90 after last purchase): Soft re-engagement. > [Name] — it’s been a while! We’ve dropped some new [products/flavors/styles] since your last order. Take a look: [link]
Message 2 (Day 97): Incentive introduction. > [Name] — we’d love to have you back. Here’s 15% off your next order, just for you: COMEBACK15 [link] — expires in 7 days.
Message 3 (Day 104): Last chance. > Last day, [Name] — your 15% off expires tonight: COMEBACK15 [link]. After that, we’ll stop texting (no hard feelings).
Message 3 doubles as a natural sunset — anyone who does not engage after three attempts is moved to your suppression list. This keeps your list clean and your delivery rates high.

4. Product Launch or Waitlist Drip
When you have a product drop, restock, or new collection launching, a drip builds anticipation before the launch and captures sales at launch.
Message 1 (1 week before launch): Teaser. > [Name] — something new is coming to [Brand] next [day]. We’ll have a first look for our text subscribers before it goes public.
Message 2 (Day before launch): Preview + early access. > Tomorrow’s the day, [Name]. Here’s your exclusive first look at [Product]: [link]. Add to your wishlist now — full drop goes live at 10 AM.
Message 3 (Launch day): Go live announcement. > It’s live, [Name]! [Product] is available now. Text subscribers get 20 minutes of early access before it goes public: [link]
Setting Up SMS Drip Campaigns in Shopify
Most Shopify SMS platforms let you build drip sequences from a visual flow builder. The setup process for any drip is the same:
- Choose your trigger. What starts the drip? Opt-in, first purchase, 90-day inactivity, waitlist signup, or custom event.
- Define your delay intervals. How many hours or days between each message? Be intentional — Day 1, Day 5, Day 14 feels different than Day 1, Day 2, Day 3 (which feels aggressive).
- Write your messages. Each one should have a single purpose. Do not combine a review request with a discount offer.
- Set exit conditions. What stops the drip? Common exits: subscriber replies, makes a purchase, or opts out. Always suppress buyers from mid-drip discount messages — there is no reason to offer 15% off to someone who just checked out.
- Connect the drip to your broader flows. Make sure cart abandonment flows and your welcome drip are not firing at the same time for new subscribers. Set priority rules.
TxtCart handles drip sequencing natively — you set the trigger and delays, and any subscriber replies during the drip are handled by TxtCart’s AI agent in real time, turning a one-way drip into a two-way conversation when the customer wants it.
Drip Frequency: How Many Messages Is Too Many?
The right frequency depends on the drip type and where the subscriber is in the relationship:
| Drip Type | Recommended Messages | Max Frequency |
|---|---|---|
| Welcome | 3 messages | No more than 1 per day |
| Post-purchase nurture | 3–4 messages | 1 per week after Day 1 |
| Winback | 2–3 messages | 1 per week |
| Product launch | 3 messages | 1 per day in launch window |
The single biggest mistake in SMS drip setup is ignoring exit conditions. If a subscriber purchases on Day 2, they should exit the welcome drip immediately. Sending a “here’s why you should buy” message to someone who already bought destroys trust and increases opt-outs.
FAQ
What is an SMS drip campaign?
An SMS drip campaign is a pre-written sequence of text messages sent to subscribers at fixed time intervals after a trigger event, such as joining your list or making a purchase. Each message in the drip fires on a schedule regardless of individual subscriber behavior, unlike triggered flows which respond to real-time actions.
How is an SMS drip campaign different from a triggered SMS flow?
A drip runs on a time-based schedule set at the trigger event. A triggered flow fires in response to specific subscriber behavior in real time, like abandoning a cart or browsing a product page. Most Shopify SMS strategies use both: drips for relationship-building sequences (welcome, post-purchase nurture) and triggered flows for high-intent recovery moments (cart abandon, browse abandon).
How many messages should an SMS drip campaign have?
Three to four messages is the sweet spot for most drip types. Welcome drips perform well at three messages over five to seven days. Post-purchase nurture drips work best at four messages over 30 days. Anything more risks opt-outs; anything less leaves engagement on the table. Always set exit conditions so subscribers stop receiving drip messages once they have completed the desired action.
What triggers an SMS drip campaign?
Common triggers include: subscribing to your SMS list (welcome drip), placing a first order (post-purchase drip), 90+ days of inactivity (winback drip), and signing up for a product waitlist (launch drip). You can also build drips triggered by custom events like loyalty tier upgrades or subscription renewals.
