SMS Cart Recovery: Timing, Copy and the Email Handoff
A cart recovery text is the shortest window in retention marketing. The shopper was on the page a few minutes ago, they may still have the tab open on their phone, and you have one line to bring them back.
The mistake most brands make is treating SMS like a shorter version of the email.
Three Messages, and Where They Sit Against the Email Flow
Text one goes between thirty and sixty minutes after abandonment. Not four hours. The phone is still in their hand and the decision is still live.
This message does one thing: it returns them to the cart, with the product name and a link.
No discount. The first message is a reminder, and discounting a reminder trains people to abandon.
Text two goes at roughly twenty-four hours, and only to people who did not open or click the first.
This one can carry a reason that is not price: low stock on the specific item, free shipping threshold distance, a delivery-by date, or the single strongest review of the product in the cart.
Text three, if you run one, goes at forty-eight to seventy-two hours and is the only place a discount belongs.
Many brands should not run it at all. If your cart abandonment is driven by price, the third text can work. If it is driven by shipping cost or account creation, the third text may simply be a discount you did not need to give.
The email side of the same cart runs on its own timing, usually one hour, twenty-four hours, and seventy-two hours, and the two channels must not collide.
The rule we apply is a sixty-minute separation between any text and any email about the same cart, with shared suppression so that a recovery in either channel stops both.
The benchmarks and structure for the email side are covered in abandoned cart benchmarks.
What the Text Should Say
Keep the message under 160 characters where possible, because a longer message can become an MMS and both the cost and rendering can change.
Lead with the product, not the brand.
Put the link at the end.
Include the brand name once, early, because a text from an unrecognised number with a link at the front can read as spam to a person as well as to a carrier.
A working shape is:
“Hey [name], your [product] is still in your cart. We saved it for you: [link]. Reply STOP to opt out.”
That message is unglamorous, but it often outperforms clever copy because the job is navigation rather than persuasion.
Use a branded link domain rather than a shared shortener. Shared shorteners can become a filtering signal, and the cost shows up as messages that were billed but never delivered.
Which Shoppers Should Get It at All
Not everyone who abandons should enter the sequence.
Exclude anyone who has already received two texts in the last twenty-four hours, anyone who bought in the last seven days unless this is a genuinely different product, and anyone whose consent is older than your engagement window without a response.
The quiet-hour and consent rules that govern all of this are covered in the SMS compliance checklist.
Segment by cart value as well.
A cart below your average order value and a cart at three times your average order value do not deserve the same sequence. A high-value cart may be better served by a person than by an automation.
Why the Channel Earns the Slot
SMS revenue continues to grow as brands invest more heavily in text-based retention.
Klaviyo reported that its brands increased text send volume by 34% year over year while text revenue increased 25%, with email and text together producing 42% of total revenue over the peak period Klaviyo BFCM report, 2 December 2025.
In our own accounts, the effect is concentrated in exactly this kind of time-sensitive automation. The Darc Sport case study showed an 80% increase in revenue from SMS automation sequences and $7.89 in revenue per campaign message sent.
Cart recovery is one of the flows we build and tune as part of our SMS marketing services.
If email and SMS are currently running as two separate calendars, the orchestration layer is covered in the email and SMS orchestration playbook.
