Drip campaigns for ecommerce: the 5 automations every store needs
The five drip campaigns every Shopify store should run: welcome, abandoned checkout, post-purchase, replenishment and winback. What each one does, and how the timing works.
Drip campaigns are the emails that send themselves: automated sequences that fire on what a customer does, not on when someone remembers to hit send. For an ecommerce store, five of them cover almost all of the always-on revenue. Set them up once, refine quarterly, and they keep working through holidays, weekends and vacations. Here are the five, with the timing that makes each one earn.
1. Welcome series: the first handshake
Trigger: someone subscribes. Sequence: 3 emails over 8 days.
- Email 1 (instant): who you are, your best sellers, one honest reason to buy from you
- Email 2 (day 3): social proof: reviews, customer photos, the story behind the products
- Email 3 (day 7): a first-purchase nudge with your standard shipping threshold, not a desperate discount
New subscribers are your warmest cold audience. The welcome series converts them while the interest is fresh, and it runs 365 days a year without anyone touching it.
One refinement that lifts the whole series: branch it by what the subscriber does. A subscriber who clicks email 1 but doesn’t buy gets email 3’s nudge sooner; a subscriber who buys anything gets moved straight into the post-purchase flow instead of receiving a first-purchase discount for an order they already made. Suppression between flows is what makes five automations feel like one smart store instead of five dumb robots.
2. Abandoned checkout: the closer
Trigger: checkout started, not completed. Sequence: email at 1 hour, email at 24 hours, SMS inside 48 hours.
This is the highest-converting automation in ecommerce because the buyer already decided: something just interrupted them. The first email helps (shipping question? sizing?), the second adds gentle urgency, and the text catches the people who left the inbox. Keep incentives out until the last touch, or you train discount-waiting.
3. Post-purchase: turn one order into two
Trigger: order delivered. Sequence: care tips at day 3, related products at day 14, review request at day 10-14.
The post-purchase window is where customer lifetime value actually gets built. Care content reduces returns and refunds; the related-products email introduces the accessory or refill that naturally goes with what they bought; and the review request feeds your social proof engine with real, dated, specific reviews.
The related-products email works best when the pairing comes from order data, not vibes: what do people who bought this actually buy next? That answer sits in your Shopify orders already. The store that pairs from its own data has a cross-sell engine; the store that pairs from gut feel has a newsletter.
4. Replenishment: the reminder that reads as service
Trigger: consumable products, timed to the product’s runout cycle.
Coils, gummies, papers, skincare, coffee: anything that runs out. The email lands a few days before the average reorder point, names the exact product they bought, and offers the one-tap reorder. No discount needed: the reminder IS the offer. This is the flow that quietly turns a one-time buyer into a quarterly recurring revenue line.
Set the cycle from the SKU, not the category. A 30ml tincture at twice daily is a 30-day cycle; the 60ml bottle is 60. The flow that reads the actual purchase gets the timing right per customer, which is the difference between “helpful reminder” and “email that shows up at the wrong time.”
5. Winback: the 60-to-90-day rescue
Trigger: no order in 60-90 days. Sequence: “we miss you” with their usual order prebuilt, then one modest offer.
Acquisition is expensive; winbacks are nearly free. A lapsed customer already knows your store, and a familiar brand with a fresh reason to return converts far cheaper than a stranger clicking an ad. The predictive scores (churn risk, forecast LTV) tell you who is worth the extra nudge.
The compliance that has to come with it
Every flow runs on consent-tracked contacts: documented opt-ins, instant opt-out processing, and deliverability guards that pause sending if bounces or complaints spike. On SMS: written consent, A2P registration and STOP/HELP handling. The automation should never put you at risk while it earns.
What the report should show
Flows are judged per flow, in dollars: welcome revenue, recovery revenue, post-purchase revenue, replenishment revenue, winback revenue, each on its own line. The monthly comparison is where the work hides: replenishment dipping while campaign revenue rises usually means the campaign cadence is stepping on the flow’s timing. How attribution assigns every order to its send.
The mistake that caps most stores’ flows
Building the five flows and never touching them again. Flows decay quietly: the welcome series keeps referencing a best seller you discontinued, the post-purchase cross-sell pairs a product you no longer stock, the winback offer repeats every quarter until regulars learn to wait for it. A quarterly flow review (one hour: check products referenced, offers live, timing still sane) keeps all five running like the day they shipped. That review is part of the monthly rhythm on a managed plan, and it is why managed flows keep converting after year one while self-built flows fade.
Build it or run it
You can build all five this month in most platforms: the flows are known. The ongoing work is the part stores underestimate: writing, designing, testing, timing, and reading the attribution. On Trinacle the five flows are built for you at onboarding, refined by your strategist, and reported in attributed dollars per flow: the monthly rhythm runs whether you touch it or not.
