Abandoned cart email vs SMS
Send the email first and send it soon, then use a text only if the cart is still there hours later and the order is worth the cost of the message. Email is nearly free, carries the product image and can explain delivery and returns. A text costs money each time and spends a piece of the permission you were given, so it belongs on carts that justify it.
Set a value floor before you build the flow. Work out what one text costs, then decide the minimum cart value where sending it makes commercial sense after the recovery rate you expect. Low value carts get the email sequence only, higher value carts get a single short text between the first and second email.
Timing does more work than wording. A cart is warm for a few hours, cooling by the next morning, and mostly gone after two days.
Choose
Abandoned cart email
when
- You have an email address but no text consent, which is the usual case
- The cart holds several items or variants that need showing again
- The reason for leaving might be delivery cost, stock or a returns question
- The cart value is too low to justify paying for a text message
- You want a sequence of two or three contacts across the next day or two
Choose
Abandoned cart SMS
when
- You hold explicit text consent from that specific person
- The cart value comfortably clears the cost of sending a message
- Stock is limited and the item may genuinely be gone tomorrow
- The first email has gone unopened and the cart is still live
- Your audience buys on a phone and rarely opens promotional email
| Criterion | Abandoned cart email | Abandoned cart SMS |
|---|---|---|
| Cost | Negligible per send, so every cart can receive the full sequence | A real cost per message that has to be earned back by the order |
| Setup effort | One flow with product blocks, timing rules and a working link back to the cart | Consent capture, quiet hour rules, short link and a value threshold |
| Time to signal | A week of carts is usually enough to read recovery | Faster per message, but you need volume above the threshold to judge it |
| Control | Full layout: images, delivery terms, reviews, support contact | One line of text and a link, with almost no room for explanation |
| Best for | Every store, at every cart value | Higher value carts, limited stock, phone first audiences |
| What can go wrong | It lands in a promotions folder hours late and the moment has passed | It arrives at a bad hour, or repeats the email, and the customer opts out |
| How we measure it | Recovered orders per thousand emails and revenue per recipient | Recovered orders per message against send cost, plus opt out rate |
When both apply
The sequence that works is short and staggered. Email within about an hour while the visit is remembered, a text some hours later only if the cart clears your value floor and consent exists, then a final email the next day that answers an objection rather than repeating the offer.
Suppress across channels so nobody gets two messages about the same cart within an hour, and stop the whole sequence the moment the order is placed. Hold any discount until the last message, since offering one immediately teaches regular customers that leaving a cart is how you get a better price.
