Abandoned cart emails work when each one answers the reason the shopper left. Baymard puts average cart abandonment at 70.22%, and extra costs are the top reason at 40%. Send three emails over three days, keep full-price shoppers away from early discounts, add SMS only with consent, and use a holdout group to prove recovered revenue.
Abandoned cart emails work when they fix the reason the shopper left, arrive while intent is fresh, and show exactly what was in the cart. The Baymard Institute puts the average documented cart abandonment rate at 70.22% across 50 studies, so most carts need no email at all: many belong to people who were only browsing. Your goal is to win back the shoppers who had a fixable problem.

Baymard also lists why shoppers who meant to buy left. Those reasons tell you what each email should say, which is where most templates go wrong: they send the same discount to everyone.
Baymard excludes shoppers who were only browsing, and among the rest 40% left because extra costs were too high, with the next four reasons running from 17% to 20%.
| Reason | Share | What the email should do |
|---|---|---|
| Extra costs too high (shipping, tax, fees) | 40% | Show the full total and any free-shipping threshold before offering a discount |
| Delivery too slow | 20% | State delivery dates and order cutoffs; offer a faster option if you have one |
| Distrust with card details | 19% | Add the returns policy, reviews, secure-checkout cues and contact details |
| Account creation required | 18% | Link straight to guest checkout |
| Checkout too long or complicated | 17% | Deep-link back to the cart with one button |
| Site errors or crashes | 17% | Fix the bug first; an email cannot rescue a broken checkout |
| Returns policy unsatisfactory | 13% | Put the policy in plain words and link it |
Fix the checkout first wherever you can. Our mobile checkout checklist covers the common leaks, and conversion rate optimization work pays back on every email you send afterwards.
We suggest this as a starting plan, not a benchmark, because the right gaps depend on your price point and buying cycle.
Test one change at a time and keep a holdout group that receives no email, so you measure recovered revenue instead of revenue that would have arrived anyway.
Plain beats clever in this email, because the shopper already wants the product.
Deliverability matters here too, because a cart email that lands in spam recovers nothing. Our email deliverability checklist covers authentication and complaint rates.
A text reminder can lift recovery, but only for people who opted in to marketing texts. Klaviyo's published benchmarks show abandoned cart flows earning $6.77 per recipient by email on average ($13.70 for the top 10%) and $4.48 by SMS ($8.69 for the top 10%). They come from one vendor's customers, so treat them as directional, not as a target.
US business texting also needs carrier registration, which we explain in our A2P 10DLC guide. Our BFCM email and SMS sequences show where the text sits in the sequence, and our WhatsApp and SMS marketing team can set it up.
One flow for everyone wastes margin, so split the audience on a few simple signals before you tune the copy.
Start with the first two. They need no new data, because your email platform already holds both.
Use these as frames and put your own voice and product details in them.
| Subject line | Body focus | Single button | |
|---|---|---|---|
| 1 (1 to 4 hours) | Your [product name] is still in your cart | Cart contents, total with shipping, one reassurance line | Return to cart |
| 2 (next day) | Questions about [product name]? Here is what buyers say | Two reviews, the delivery date, returns in one sentence | Complete your order |
| 3 (day three) | Last reminder: [product name] before [real date] | A real deadline or stock level, plus the incentive if you use one | Finish checkout |
Illustrative example: you send the flow to 4,000 abandoned carts in a month, 3% convert after the email, and the average order is $60. That is 120 orders and $7,200. A holdout group that received no email converted at 1.5%, so about half of those orders would have happened anyway. The flow caused roughly 60 orders, or $3,600. Judge the flow by the holdout, not by the dashboard, and use your own rates instead of these.
Baymard and the FTC are primary sources read on 28 October 2026. Klaviyo figures are vendor data from its own customers and are directional. The timing plan and the worked example are our judgment, and the example uses hypothetical numbers.

There is no verified universal timing, so treat ours as a starting plan to test: the first email one to four hours after abandonment, the second the next day, and a final reminder on day three. Adjust the gaps to your price point and how long your buyers usually take to decide.
Three is a sensible starting point: a prompt reminder, a reassurance email with reviews and delivery details, and a final reminder with a real deadline. More emails can add recovered orders but also add unsubscribes and complaints, so test a fourth message against a holdout before you keep it.
Usually not. Baymard finds that extra costs are the top reason for abandonment, so show the full total and delivery details first. Holding any incentive for the last email avoids training full-price shoppers to abandon on purpose and keeps your margin intact.
Treat it as commercial email to be safe. The FTC guide asks for accurate headers and subject lines, a valid physical postal address, a clear opt-out, and honoring opt-outs within 10 business days. Your email platform should handle the unsubscribe, but you remain responsible for compliance.
No. Text messages need the shopper's consent to receive marketing texts, and US business texting also needs carrier registration. Send SMS reminders only to people who opted in, and make opting out as easy as opting in. Ask your counsel about state rules.
Hold back a random group that receives no abandoned cart email and compare its conversion rate with the group that does. The difference is the revenue your flow caused. Without a holdout, the dashboard also counts orders that would have happened anyway.
