Klaviyo’s own benchmark data puts automated flows at roughly 5.3% of sends and about 41% of email revenue. Something like eighteen times the revenue per recipient of a one-off campaign.
Read that against how your week actually goes. You spend it on the campaign calendar, writing the Thursday send, arguing about the subject line. The four things producing most of the money were built once, probably by whoever set up the account, and nobody has opened them since.
That ratio is the entire argument for spending this morning on flows rather than on next week’s newsletter.
Four of them carry nearly everything: welcome, checkout abandonment, browse abandonment and post purchase. Build them in that order. Here’s what each should say, when it should say it, and the one number that tells you it’s working.
Welcome, which is your highest intent audience all year
Somebody just handed you their email address on purpose. They will never be more interested than they are in the next ten minutes.
Klaviyo’s benchmarks give the welcome series the highest entry click rate of any flow, around 9.2%, with entry conversion near 4.4%. Reported revenue per recipient sits somewhere in the $3 to $8 range depending on category.
Three emails, and the mistake is making all three about the discount.
Email one, immediately. Deliver whatever you promised, code or guide, in the first line. Then one short paragraph on why the company exists. Not a founder essay. Two sentences a human would say out loud.
Email two, day two. The thing your customers actually ask before buying. Sizing, materials, how it compares to the obvious alternative, how returns work. This is the email that removes the objection, and it usually outperforms the discount email.
Email three, day four. Social proof and a specific product. Reviews, a photograph of the thing in use, one clear link. Not your whole catalog.
The metric: conversion rate on the whole series. If it’s under 4%, your promise and your first email don’t match.
Checkout abandonment, the one that earns most per person
Klaviyo’s figures put this flow at the highest revenue per recipient of any automation, around $3.65, on roughly 50% open and 6% click.
Three emails, and the sequence matters more than the copy.
One hour. No discount. A reminder with the item, the image, and a single button back to the cart. A large share of abandonment is a phone going in a pocket, and this email just finishes the errand.
Twenty four hours. Handle the objection instead of cutting the price. Shipping cost and timing, returns policy, the review that answers the hesitation. Unexpected shipping cost is the most common reason a cart dies and you can address it directly.
Forty eight to seventy two hours. Now, if your margin supports it, the incentive. Free shipping usually beats a percentage discount, and it costs you less.
The metric: placed order rate, which benchmarks put around 3.3% and higher for good implementations. And watch what share of recovered revenue came from the third email, because if it’s most of it you’re paying a discount to people who were going to buy anyway.
Browse abandonment, the one most stores skip
Somebody looked at a product and left without adding it. Weaker intent, much larger audience, and reported revenue per recipient in the $1 to $4 range with open rates around 25% to 30%.
One or two emails, not three. The tone is the whole thing here: you are not chasing a purchase, you are being useful about a category.
Send at four to six hours, showing the product they viewed plus two genuine alternatives. Then, if you send a second, make it about the category rather than the item. Questions people ask, how to choose, what the differences actually are.
Exclude anybody who has entered the checkout flow, or you’ll send two overlapping chases and look like you’re following them around.
The metric: revenue per recipient against your campaign average. If it isn’t comfortably above, your timing is wrong or your exclusions are leaking.
Post purchase, which is where margin actually lives
The highest engagement of any flow, with reported open rates of 60% to 70% and revenue per recipient around $2 to $5.
That attention is a gift and most stores waste it on a receipt.
Immediately after ordering. Confirmation, plus one paragraph setting expectations. When it ships, how to reach a human, what to do if something’s wrong. This paragraph is why your support inbox gets quieter.
On delivery. How to use or care for the thing, properly. This is the email that reduces returns, and it’s the one nobody writes.
Seven to fourteen days later. Ask for the review. One question, one link, no bundle of requests.
Thirty to sixty days later, timed to your product. The replenishment or complementary purchase. If you sell something consumable, this email is the single highest return automation in your account and the timing should match how long the product lasts, not a round number.
The metric: repeat purchase rate within ninety days. That’s the number that compounds, and it’s the one that decides whether your acquisition cost is survivable.
None of it matters if you’re in spam
A flow landing in the promotions tab earns nothing, and the floor moved.
Google, Yahoo and Microsoft now expect bulk senders to authenticate with SPF, DKIM and DMARC, to offer one-click unsubscribe under RFC 8058, and to keep spam complaints under 0.3% as measured in Postmaster Tools, with under 0.1% the real target. Fail badly enough and mail is rejected outright rather than filtered.
The authentication side is the same work I went through for cold outbound, so I won’t repeat it here. Set it up once, for the sending domain Klaviyo actually uses, and verify it rather than assuming.
The part specific to ecommerce is list hygiene, and it’s the thing that protects the 0.3%.
Stop sending campaigns to everybody. Build an engaged segment of people who opened or clicked in the last 90 to 120 days and send your campaigns there. Suppress the rest, and run a short reactivation flow at them separately. Two emails, and if nobody responds, let them go.
A smaller list that gets delivered outperforms a large one that trains Gmail to file you. Compliant senders are reported to see inbox placement near 89% while non-compliant senders lose a quarter or more of their mail to spam, and that gap is larger than any subject line test you’ll ever run.
Before lunch
An hour, in order.
Open your flows tab and sort by last edited. Whatever hasn’t been touched in a year is where your morning goes.
Then check which of the four you’re missing. Most stores have welcome and checkout abandonment, and are missing browse abandonment and the post purchase replenishment email entirely.
Then open Google Postmaster Tools and look at your spam complaint rate. If it’s over 0.1%, build the engaged segment today, because everything above this line depends on it.
My notes on content marketing cover what to write once the plumbing works. If you’d like a second opinion on your own flows, drop me a line on email, WhatsApp or LinkedIn and we can have a quick chat. I’m contracted full time so this isn’t a pitch.
