Campaigns get the attention. Flows generate the revenue. If your Shopify store only has a basic abandoned cart email running, you are leaving a significant portion of your potential email revenue on the table every single day.
Email flows — also called automated sequences or triggers — fire based on customer behaviour. They run without you. A customer abandons a cart at 2am on a Sunday: your flow sends the recovery email. Someone buys for the third time: your VIP flow fires automatically. No manual work required once they are built.
Here are the flows that matter, in order of the revenue they typically generate.
1. Welcome Series
Revenue impact: high. Build this first.
New subscribers are at peak interest. They just opted in. A welcome series turns that interest into a first purchase before it cools.
Structure: 4–5 emails over 10 days.
- Email 1 (immediate): Deliver what you promised — discount, lead magnet, early access. Confirm they made a good decision joining.
- Email 2 (day 2): Your brand story. Why does this store exist? Make it human, not corporate.
- Email 3 (day 4): Social proof — bestsellers, reviews, customer results.
- Email 4 (day 7): Address the main objection. What stops people buying from you for the first time? Answer it directly.
- Email 5 (day 10): Final push. Use urgency if your discount has an expiry. Make the CTA unmistakable.
One rule: do not lead with a hard sell in email one. Earn the pitch first.
2. Abandoned Cart Flow
Revenue impact: very high. If you have one, make sure it is structured correctly.
This is the most widely deployed flow — and the most widely done wrong. Three emails is the correct structure. Most stores either send one (too few) or send five with a discount in email one, which trains customers to abandon intentionally.
- Email 1 (1 hour after abandonment): Simple reminder. Show the cart. No discount yet. Just make it easy to come back.
- Email 2 (24 hours): Address the real objection — shipping cost, return policy, product quality concern. Use this email to remove doubt.
- Email 3 (48–72 hours): Final chance. Now you can introduce an incentive if margins allow — but frame it as a limited offer, not a desperate plea.
A well-built three-email flow typically recovers 8–15% of abandoned carts. For most Shopify stores, that is the highest-ROI email asset they own.
3. Post-Purchase Flow
Revenue impact: high. Drives repeat purchase rate.
The moment someone buys is the moment they are most engaged with your brand. Most stores waste it by sending only a transactional order confirmation.
Your post-purchase flow should do four things:
- Reassure: Confirm the order, set delivery expectations, reduce post-purchase anxiety
- Educate: Help them get maximum value from what they bought — tips, tutorials, usage guides
- Collect reviews: Time this 7–14 days after delivery, when the product experience is fresh
- Cross-sell: 3–4 weeks out, introduce a complementary product that logically follows from what they bought
Repeat purchase rate is one of the most direct drivers of profitability. Every second purchase costs you nearly nothing in acquisition. Your post-purchase flow is the system that makes it happen consistently.
4. Browse Abandonment Flow
Revenue impact: medium. Build once core flows are running.
This triggers when a logged-in or cookied subscriber views a product but does not add to cart. Lower intent than cart abandonment, but volume is often 5–10x higher. A 1–2% conversion rate on high traffic makes this flow worthwhile. Keep it simple: one or two emails showing the product they viewed plus related alternatives. No heavy selling — match the low-pressure energy of browsing behaviour.
5. Winback Flow
Revenue impact: medium. Build when your list reaches meaningful size.
Customers who bought 90–180 days ago and have not returned are not lost yet — but they are drifting.
- Email 1: Re-engagement. Acknowledge the gap. Share what is new. Give them a reason to look again.
- Email 2: Stronger offer — a discount, a bundle, a free shipping threshold.
- Email 3: The breakup email. Honest and direct: “This may be the last time we reach out.” This email consistently has the highest open rate of the sequence because it creates genuine urgency without feeling manipulative.
Anyone who does not engage with the winback flow should be suppressed. Continuing to email cold contacts hurts your deliverability for everyone else on your list.
6. Back-in-Stock and Price Drop Flows
Revenue impact: situational but high when triggered.
If you sell products that go out of stock, a back-in-stock flow is non-negotiable. The customer already told you they want the product by joining the waitlist. This is the easiest conversion in email marketing — they are pre-sold.
Price drop flows work similarly for customers who viewed a product but did not buy. Alerting them when the price changes removes the one objection standing between them and a purchase.
How to Prioritise What to Build First
If you are starting from scratch or rebuilding a neglected email setup, build in this order:
- Welcome series
- Abandoned cart (3 emails)
- Post-purchase
- Winback
- Browse abandonment
- Back-in-stock / price drop
Do not try to build all six at once. Get the welcome series and abandoned cart running first — those two alone will generate the majority of your automated email revenue. Then add the others as your operation matures.
The goal is a system that converts, retains, and reactivates customers without you having to touch it every week. Build it once. Optimise it over time. Let it run.
