Before the rebrand, before the ad account, before the tenth app subscription: seven automations, ranked by the published revenue-per-email data, with the numbers each one should hit.
Stores collect email apps the way kitchens collect gadgets, and meanwhile the flows that actually pay sit half-built. The data on this is not subtle. In Klaviyo’s 2026 benchmarks, automated flows convert at a 2.11% placed order rate against 0.16% for campaigns, and produce nearly 41% of email revenue from 5.3% of sends. Omnisend’s 2025 dataset prices the same gap: $3.41 revenue per automated email versus $0.155 per campaign email, a 22x difference.
Flows are infrastructure. You build them once, they run while you sleep, and the only real question is which ones to build and in what order. Omnisend publishes per-automation economics, which means the priority list does not have to be anyone’s opinion. Here are the seven, ranked by what the published numbers say each send is worth.
1. Welcome. The front door. $6.16 per email, 35.53% open rate and a 2.11% conversion rate in Omnisend’s data, and, per Klaviyo’s benchmarks, a 51% average open rate under its methodology. Together with cart recovery it drives 76% of automation-generated orders. Structure, timing and the incentive logic get their own treatment in our welcome flow guide.
2. Abandoned cart. The highest-intent trigger a store has: someone chose products and stopped at the finish line. Omnisend’s table has it at $3.59 per email with a 1.72% conversion rate, and it was the most widely adopted revenue automation in the dataset, active in 22.5% of brands. If your store still lacks one, start with our cart flow timing piece because the first-email delay decides most of the outcome.
3. Back in stock. The best per-email economics in the entire published table, $9.14 per send and a 6.72% conversion rate, and the least adopted: 0.6% of brands. The math is easy to explain, since the trigger is literally a customer asking to be emailed when a product returns. If your catalog never sells out, skip it guilt-free; for everyone else this is the cheapest revenue in email.
4. Order follow-up (post-purchase). The flow that turns first-time buyers into the repeat customers your retention rate depends on. $1.75 per email at a 47.70% open rate in Omnisend’s data, and the open rate is the point: nobody reads email like a customer waiting for their package. Sequencing, content and cross-sell timing are covered in our post-purchase flow guide.
5. Browse abandonment. Fires when a known subscriber views products and leaves without carting anything. Lower intent, thinner economics ($0.76 per email, 0.59% conversion), but enormous audience, since browsers vastly outnumber carters. It is the flow almost nobody builds, which is exactly why it gets its own numbers-first treatment in the browse abandonment piece.
6. Review request (customer feedback). $1.14 per email and a 49.17% open rate, but its real yield is off the books: the reviews it harvests raise the conversion rate of every product page for every future visitor. One well-timed ask per order, positioned after delivery, is the whole flow.
7. Win-back (reactivation). Last by design. $0.51 per email and a 0.54% conversion rate, the weakest row in the table, and still worth building because it runs at near-zero cost against customers you already paid to acquire, and because its final email doubles as your list-hygiene gate. The full machinery, from lapse definition to suppression, is in our win-back mechanics guide.

| Flow | Open rate | CTR | Conversion | Unsubscribe | |
|---|---|---|---|---|---|
| Back in stock | 58.80% | 21.31% | 6.72% | $9.14 | 0.37% |
| Welcome | 35.53% | 3.94% | 2.11% | $6.16 | 0.87% |
| Abandoned cart | 37.12% | 4.13% | 1.72% | $3.59 | 0.45% |
| Order follow-up | 47.70% | 4.12% | 0.93% | $1.75 | 0.86% |
| Customer feedback | 49.17% | 4.29% | 0.98% | $1.14 | 0.57% |
| Browse (page viewed) | 44.47% | 8.53% | 0.59% | $0.76 | 0.51% |
| Win-back (reactivation) | 33.11% | 1.99% | 0.54% | $0.51 | 0.68% |
Sort by open rate and notice the pattern: the flows tied to a purchase (feedback at 49.17%, order follow-up at 47.70%) open like transactional mail, while the pre-purchase flows open like very good marketing. Sort by unsubscribe rate and the welcome flow’s 0.87% tops the list, which is not a defect; new subscribers deciding early whether they want you is the system working.
Do not build all seven in one weekend. Each flow needs a trigger tested, a suppression rule checked against the others, and a week of real traffic before you trust it. Two flows per month is a sustainable pace that gets a store from zero to fully automated inside a quarter.
Do not let flows and campaigns collide. A subscriber can be in three flows at once by accident, plus your Tuesday campaign. Serious platforms handle this with flow exclusions and smart sending; your job is to switch those on and decide the priority order, which the seven-item ranking above already gives you.
And do not judge the weak flows by the strong flows’ numbers. A win-back email earning $0.51 looks embarrassing next to back in stock’s $9.14 until you remember they answer different questions: one converts demand that already exists, the other manufactures a second chance. Every row in that table out-earns the $0.155 a campaign email makes. That is the bar, and all seven clear it.
All per-automation metrics (open rate, CTR, conversion rate, revenue per email, unsubscribe rate, plus adoption figures of 22.5% for abandoned cart and 0.6% for back in stock) are from the automation table in Omnisend's benchmarks article published May 12, 2026, based on its 2025 dataset of 470 million automated sends across 27,000+ brands. Omnisend labels the browse trigger "page viewed" and win-back "customer reactivation"; I kept its numbers and used the common names. Flow-versus-campaign comparisons (2.11% vs 0.16% placed order rate, 41% of email revenue from 5.3% of sends) are from Klaviyo's benchmarks published February 24, 2026, covering 183,000+ brands. The 76% welcome-plus-cart share of automation orders is from Omnisend's welcome subject lines article published June 15, 2026. The two vendors define conversion differently, so cross-vendor rows are never averaged in this piece.
Welcome and abandoned cart, in either order, because they cover the two highest-intent moments a store has and, per Omnisend's data, together account for 76% of all automation-generated orders. Back in stock earns more per email ($9.14) but only matters if your catalog actually sells out and returns.
Two to four for the pre-purchase flows (welcome, cart, browse), one to two for the transactional-adjacent ones (back in stock, review request), three to four for win-back. Beyond that, each additional email in a flow tends to add unsubscribes faster than orders, which is visible in the flow unsubscribe rates Omnisend publishes.
No. The flow logic is identical in Klaviyo, Omnisend, Mailchimp or any platform with behavioral triggers. The benchmarks quoted here come from Klaviyo's 2026 report (183,000+ brands) and Omnisend's 2025 dataset (27,000+ brands), and the ranking of flows by value is consistent across both.
The same triggers work over SMS and the published economics are strong, but build the email versions first: they are near-free to send, and the flow logic you debug in email transfers directly. We covered the SMS side and its costs in our SMS payoff piece.
