Why flows first
A flow email is worth about 5 times a campaign email per recipient in our 2026 benchmark: $1.07 against $0.20. Flows run on behaviour, send at the right moment to one person, and keep earning without anyone pressing send. That is why a Klaviyo setup starts with flows and why the first 30 days of any program we run go there.
The five below cover 80% to 90% of flow revenue in a typical store. Category flows (back in stock, replenishment, price drop, VIP) come after.
1. Welcome
Job: turn a popup signup into a first order and teach the brand. Emails: 3 to 5 over 7 to 10 days. First email immediately with the offer (if any) and the three things to know about the brand; second with the best sellers and social proof; third with the story or the founder; fourth with the offer reminder; fifth with a reason to reply or follow. Trigger and filters: subscribed to the main list; exit on purchase; suppress anyone who bought in the last 30 days (checkout opt-ins). What decides the earn: the offer and the popup rate behind it. A first-order offer gets a 5% to 10% popup and a welcome flow that converts; “join our newsletter” gets 1% to 2% and a flow that educates. Both are valid; luxury and medical pick the second (why).
2. Abandoned checkout
Job: recover the people who started checkout and left. Emails: 3 over 48 hours. First at 1 hour (the cart, one line, one button); second at 24 hours (objections: shipping, returns, sizing, a review); third at 48 hours (last reminder, an offer only if the brand uses offers). Trigger and filters: Started Checkout; exit on Placed Order; filter out orders placed through any channel in the window. What decides the earn: the objections email. In fashion it is fit and returns; in home decor, shipping and the room shot; in medical, delivery and installation. A flow that only repeats the cart earns half of one that answers the question.
3. Browse abandonment
Job: bring back the person who viewed a product and did not add it. Emails: 2 over 24 to 48 hours. First at 2 to 4 hours with the exact product and two real alternatives; second the next day with the category and social proof. Trigger and filters: Viewed Product (from the Shopify integration, not Active on Site); once per 7 days per person; exit on Started Checkout or Placed Order; suppress if the product is out of stock, with a fallback block. What decides the earn: the alternatives and the sold-out state. In our fashion stores browse abandonment is the biggest flow by revenue; the version that shows the same item in the other colour or the same size in a sister style beats “you looked at this” by a wide margin.
4. Post-purchase
Job: make the first order the start of a relationship, and sell the second one. Emails: 4 to 6 over 30 to 60 days. Thank you with what happens next (immediately); how to use or care (at delivery); review request (7 to 21 days after delivery depending on the product); cross-sell of the complement (belt to shoes, rug pad to rug, accessory to device); a reason to come back (new arrivals in the category) at 30 to 45 days. Trigger and filters: Placed Order; branch on first order against repeat; branch on product category for the cross-sell. What decides the earn: the cross-sell logic and the timing from delivery, not from order. The rug store earns from a rug-pad email timed to delivery; the same email at order time is ignored.
5. Winback
Job: bring back customers who stopped buying. Emails: 2 to 3. First at the point where the customer is late against the store’s real repurchase cycle (not a default 60 days); second two weeks later with what is new; third with an offer, if the brand uses offers. Trigger and filters: Placed Order with a time delay equal to the category’s cycle (consumables 30 to 90 days, fashion 120 to 180, home decor 300 and more for small items); exit on Placed Order; suppress VIPs who are in a different sequence. What decides the earn: the delay. Klaviyo’s predicted next order date, where the store has enough history, beats any fixed number.
The four things that break flows
- Wrong trigger. Active on Site instead of Viewed Product; Checkout Started from an app that fires it on cart view.
- No exit conditions. The customer buys and still gets email 3. The single most common finding in audits.
- One email per flow. Half the revenue is in emails 2 and 3.
- Static product blocks. The flow shows the best sellers instead of what the person looked at.
What the Setup includes
Our one-time Setup ($1,500) builds all five flows with the logic above, a branded template, popups (welcome and winback), core segments, and deliverability (dedicated domain, SPF, DKIM, DMARC, warm-up, list hygiene), with revisions until approved. Stores that already have a working foundation skip it and start on a retainer. The free 30-minute audit tells you which of the five you have, which fire, and what each earns per recipient today.
The next benchmark, before it is public
Every quarter we re-pull the numbers from the accounts we run and send the summary first to the list, with the teardowns in between. No weekly newsletter, no discounts, unsubscribe in one click.
