Most stores send too many campaigns and run too little automation. That is backwards. Campaigns are one-time sends to your whole list. Flows are triggered messages that fire when a customer does something, and they run without you touching them. In the accounts I manage, flows produce 30 to 40 percent of total email revenue while accounting for a fraction of the sends. They convert better because they reach people at the moment intent is highest.
Here are the four flows that carry that revenue, and how to build each one.
Key takeaways
- Automated flows earn close to a third of ecommerce email revenue from a small share of the sends.
- Abandoned checkout is the highest-earning flow; trigger it on checkout start, not add-to-cart.
- Build in revenue order: checkout, welcome, post-purchase, then browse.
- Judge a flow by revenue per recipient, not by open rate.
Abandoned checkout
This is the highest-earning flow in almost every store. Someone entered the checkout, gave you their email, and left. They were ready to buy, and yet about 70 percent of carts are abandoned before purchase. Your job is to remove whatever stopped them.
Trigger it on checkout start, not on add-to-cart. Add-to-cart is browsing behavior. Checkout start is purchase intent, and the difference in conversion is large. I break down that trigger choice in Klaviyo on its own.
Build three messages:
- Message one, 45 to 60 minutes after abandon. No discount. Show the exact items they left, restate your return policy and shipping, and give one button back to checkout. Many recoveries happen here because the person got distracted, not because of price.
- Message two, 24 hours later. Handle objections. Answer the questions that stall a purchase: sizing, materials, delivery speed, warranty. Add two or three review quotes for the product in the cart.
- Message three, 48 hours later. Now you can test an incentive. Free shipping often beats a percentage off because it does not train people to expect discounts.
Suppress anyone who completes the purchase, and exclude buyers who already ordered that item. Nothing burns trust faster than a discount email for something a customer bought an hour ago, and spam complaints are the one signal Gmail’s sender rules punish hardest.
Abandoned browse
This catches people who viewed a product and left before adding it to the cart. Intent is lower than checkout abandon, so the flow is shorter and softer.
Trigger on a product view with no add-to-cart and no purchase in the following hours. Send one message two to four hours later showing the viewed product, and a second message the next day featuring the same category with two alternatives. Keep the tone helpful, not pushy. You are reminding, not chasing.
Cap the sends so a browser who looks at ten products does not get ten emails. One entry per profile per 24 hours is a sane rule.
Welcome series
Someone signed up and has not bought yet. This is your warmest audience of the week, and a plain single welcome email leaves money on the table. Build a sequence of four to five messages over seven to ten days.
- Email one, immediate. Deliver the signup offer if you promised one, and set expectations for what you send.
- Email two, day two. Tell the founding story and why the product exists. People buy from brands they understand.
- Email three, day four. Show your best sellers with social proof. Let the catalog do the selling.
- Email four, day six. Address the top two objections that keep first-time buyers from ordering.
- Email five, day eight. A deadline on the welcome offer, if you used one.
Move anyone who buys out of the series and into your post-purchase flow. The welcome series is where you teach a stranger to trust you, so front-load value and hold the hard sell until email three.
Post-purchase
This flow decides whether a first order becomes a second. Repeat buyers cost nothing to acquire and spend more per order, so this is where lifetime value is won.
- Order confirmation and shipping updates. These get open rates above 60 percent, so use them. Add a related-product suggestion and a line about your community or referral program.
- Delivery-plus-three-days. Ask how the product is working out and point to setup or usage tips. This lowers returns and raises satisfaction.
- Review request, roughly a week after delivery. Time it to when the customer has used the product long enough to have an opinion.
- Replenishment or cross-sell, timed to the product. For consumables, trigger a reorder reminder a week before the average runs-out date. For durable goods, suggest the natural next purchase.
The build order that makes sense
Do not launch all four at once. Build in revenue order so cash comes in while you work:
1. Abandoned checkout
2. Welcome series
3. Post-purchase
4. Abandoned browse
Each flow needs an entry trigger, exit conditions, and suppression rules. The exits matter as much as the triggers. A customer who receives an abandonment email after buying, or a review request for a returned item, learns that your automation is not paying attention.
Measure the right number
Do not judge a flow by open rate. Judge it by revenue per recipient, which is total flow revenue divided by the number of people who entered. That number tells you what each additional person in the flow is worth, and it lets you compare flows honestly. When you rework a message, watch revenue per recipient over the next 30 days, not the open rate the next morning.
Takeaway
Four flows carry the load: abandoned checkout, welcome, post-purchase, and abandoned browse. Build them in that order, wire the exit and suppression rules with care, and track revenue per recipient. Do that and automation will earn a third of your email revenue while you sleep.
