WhatsApp for ecommerce.
In short
Online shops get most of their value from WhatsApp on the utility side, not the marketing side. Order confirmations, dispatch notices and delivery updates are utility templates, which cost a fraction of the marketing rate and are welcome rather than tolerated. Opt-in comes from an unticked checkbox at checkout that names the shop and says messages will arrive on WhatsApp. The most common way a shop damages its number is treating abandoned-cart messages as utility when Meta reads them as marketing.
Why it works here
The cheap messages are the valuable ones.
A delivery update read in four minutes beats an email read tomorrow. The unglamorous transactional messages are also the cheap ones — the opposite of what most shops assume when they arrive.
Where consent comes from
An unticked checkbox at checkout, next to the phone field, saying plainly that this shop will send order updates on WhatsApp. That covers the order. It does not cover next month’s sale, which needs its own opt-in — a completed purchase is not consent to be marketed to.
The full opt-in rulesThe messages
What to send, and what it costs.
Meta prices by category, so which category your message lands in matters more than almost anything else you can control. Utility is a small fraction of marketing.
How Meta charges-
Order confirmed, with the order number and total.
UtilityAbout a transaction they already have with you. Cheapest category, and nobody minds receiving it.
-
Dispatched, with the courier and the tracking link.
UtilityStill the same transaction, and the message that removes the "where is my order" ticket.
-
Out for delivery today.
UtilityReduces failed deliveries, which is real money rather than engagement.
-
The sale starts Friday.

The mistake
Specific to this trade
The abandoned cart message
A shop reasons that the customer added the item themselves, so a reminder is transactional. Meta does not read it that way: an incomplete order is not a transaction, and a nudge to buy is marketing whatever it is called. Submitted as utility it gets rejected; sent to people who only agreed to order updates, it gets reported. Treat them as marketing, get marketing opt-in, and send one rather than three.
WhatsApp is not a replacement for a returns process. A customer who cannot start a return without messaging you has been given a slower experience wearing a faster channel.
