A shopping cart abandonment email is a message sent to a shopper who added an item to their cart and left without paying, and the most effective ones answer a simple question for the reader: why come back and finish this. Getting it right is less about clever copy and more about timing, clarity and a subject line that earns the open. This guide covers when to send a shopping cart abandonment email, what it should say, who should receive one, and the mistakes that quietly reduce how well the sequence performs.
Why a Shopping Cart Abandonment Email Matters
Cart abandonment is one of the most consistent patterns in ecommerce. Research from the Baymard Institute, which has tracked this across many studies for years, puts average online cart abandonment well above two-thirds of all shopping sessions. Shoppers get distracted, compare prices elsewhere, hit an unexpected shipping cost, or simply run out of time before they finish checking out.
A well-built shopping cart abandonment email recovers a meaningful slice of that lost revenue without any extra acquisition spend. The shopper has already shown intent by picking a product and starting checkout, which makes them a far warmer audience than a cold ad impression, and that is why this message is one of the highest-return emails a business sends.
When to Send a Shopping Cart Abandonment Email
Timing matters more than most of the copy decisions that follow. A shopping cart abandonment email sent too late arrives after the shopper has already bought the item elsewhere or lost interest entirely. Sent too early, before they have genuinely stopped shopping, it can feel intrusive.
First email: around one hour after abandonment. This is a simple reminder, not a hard sell. The shopper may have just stepped away or is still deciding, so a short, plain message showing the item still in their cart is usually enough.
Second email: between 24 and 48 hours later. By this point the shopper has had time to think it over or shop elsewhere. This email can add a bit more substance: answer a likely objection, highlight a relevant product detail, or show social proof if you have genuine reviews to draw on.
Third email: around 72 hours after abandonment. This is the point many businesses consider a time-limited incentive, such as free shipping or a small discount, if the margin supports it. Training shoppers to expect a discount every time they abandon a cart can quietly erode margin, so test the sequence without one first and weigh any recovered revenue against the discount's cost.
Three emails is a sensible default, not a hard rule. Lower order values or faster purchase decisions can get away with two, while a longer, more considered purchase might justify one or two additional nudges spaced further apart. A sequence that drags on for a week or more tends to produce diminishing returns and rising unsubscribe rates.
What a Shopping Cart Abandonment Email Should Say
The Subject Line
The subject line decides whether the rest of the email gets read at all. Subject lines that work well here tend to be direct rather than clever: naming the item, asking a simple question, or flagging that the cart is still saved. Vague, curiosity-driven subject lines tend to underperform for this type of email, because the shopper already knows exactly what it is about. There is no need to disguise it.
The Body
The body works best when it does four things, roughly in this order:
Shows the item. A clear image and name of the product left in the cart, so the shopper recognises it immediately.
Removes one piece of friction. This might mean restating the delivery estimate, clarifying the return policy, or confirming the price shown includes tax. Unexpected costs at checkout are one of the most commonly cited reasons shoppers abandon a cart, so addressing that directly often does more than a discount would.
Gives a single, clear call to action. One button returning the shopper to their cart, ideally with the item still saved and ready to buy. Avoid cluttering the email with unrelated product recommendations or competing links, since every extra choice is a chance to click away from the one action that matters.
Keeps the tone human. This is not the place for manufactured urgency, such as a countdown timer claiming the item will sell out in minutes when that is not true. Shoppers spot manufactured urgency easily, and it damages trust in future emails from the same sender.
A shopping cart abandonment email does not need to be long. The shopper already knows the product and already considered buying it once, so the job of this email is to remove whatever stopped them, not to re-pitch the entire product from scratch. Most effective versions fit comfortably above the fold on a phone screen.
Who Should Receive a Shopping Cart Abandonment Email
Not every abandoned cart deserves the same treatment. A returning customer who has bought from you before behaves differently to a first-time visitor who added something out of curiosity, and treating every abandonment the same way wastes some of the email's potential. This is where behavioural segmentation earns its place in the setup: a returning customer with a history of completing purchases might only need the single, simple reminder, while a first-time visitor might benefit from the longer second email that answers common objections, since they have no prior experience with your business to fall back on.
It is also worth excluding certain groups entirely. Shoppers whose cart contained a product later marked unavailable should not receive a generic reminder pointing them back to something they cannot buy. Checking cart contents against current inventory before sending avoids this common mistake.
Common Mistakes With Shopping Cart Abandonment Emails
Sending only one email and stopping. A single reminder captures some of the available recovery, but most of the lift from cart abandonment emails comes from the sequence as a whole, not any one message.
Leading with a discount by default. Jumping straight to a percentage off in the first email trains shoppers to abandon carts on purpose, waiting for the discount to arrive. Reserve any discount for later in the sequence, and only if the margin on your products supports it.
Ignoring mobile formatting. A large share of cart abandonment happens on mobile, often because checkout on a small screen is more fiddly than on desktop. If the recovery email itself renders poorly on a phone, with a tiny button or a slow-loading image, it undoes the point of the message.
Treating the sequence as separate from the rest of lifecycle email. A shopping cart abandonment email should sit inside the same system as your broader post-purchase email flow, using the same brand voice, sender name and unsubscribe logic as every other automated email a customer receives.
Not testing timing for your own audience. The windows above are a reasonable starting point, but the right timing depends on your typical purchase cycle and average order value. A considered, higher-value purchase may need a longer delay before the first email, since the shopper genuinely needs more time to decide.
Setting This Up Without Reinventing It
Most major email platforms support cart abandonment sequences as a built-in flow rather than something you need to build from scratch. Klaviyo's documentation covers setting up triggers based on checkout started events, and the same logic applies broadly across other platforms with slightly different naming. For the technical setup steps on one specific platform, a guide to building a Klaviyo abandoned cart flow covers the trigger, timing and conditional logic in more detail than is useful to repeat here.
Measuring Whether It Is Working
The two numbers that matter most are the open rate of each email in the sequence and the overall recovery rate: the percentage of abandoned carts that convert to a completed purchase within a set window, typically seven days. General benchmarks, such as those Mailchimp publishes for open and click rates, give a useful point of comparison, though cart abandonment emails typically outperform standard marketing email because the audience has already shown clear purchase intent.
If recovery rate is low despite reasonable open rates, the problem usually sits in the body of the email rather than the subject line: an unclear call to action, a broken link back to the cart, or checkout friction the email never addressed. If open rates themselves are low, look first at the subject line, the sender name, and the timing of the first send.

Frequently Asked Questions
How many emails should be in a shopping cart abandonment sequence?
Three is a sensible default: a simple reminder within the first hour, a fuller message a day or two later, and a final message around three days out that may include an incentive if the margin supports it. Fewer or more can work depending on purchase cycle and order value.
Should a shopping cart abandonment email always include a discount?
No. Leading with a discount in the first email can train shoppers to abandon carts deliberately, expecting a reward for coming back. A discount is more defensible later in the sequence, and only worth including once you have checked the margin can absorb it.
What is a good open rate for a shopping cart abandonment email?
It varies by industry and list quality, but these emails typically perform above the average for standard marketing email, since the recipient has already shown clear intent to buy. Comparing your own results over time, against benchmarks such as those Mailchimp publishes, is more useful than chasing a single universal number.
Should abandoned cart emails be sent by SMS as well as email?
Some businesses add an SMS reminder alongside the email sequence, particularly for time-sensitive items, provided the shopper has opted in and the message complies with regulations such as those outlined in Twilio's messaging documentation. It should supplement the email sequence, not replace it.
What should happen if the abandoned item goes out of stock?
The shopper should be removed from the sequence or moved into a different message, such as a note that the item is unavailable with a similar alternative. Sending a standard reminder pointing to a product that can no longer be bought wastes the email and reflects poorly on the rest of your communications.
