The volume argument, stated plainly
A seller shipping thirty high-value orders a month could, in theory, write thirty personal messages. It would be tedious, but it is possible, and plenty of good sellers do exactly that.
A seller shipping three thousand low-value orders a month cannot. There is no version of that person's week that contains three thousand messages. So they send none, and they collect reviews at whatever rate happens naturally — roughly one buyer in a hundred, skewed towards the annoyed ones.
That is the entire case for automation in value fashion. It is not that a machine writes a better message than you would. It is that the machine writes the message at all.
Family orders make the review about the basket
Kiabi's buyers frequently buy for several people at once: something for each child, a couple of things for themselves. That is a different psychological object from a single considered purchase.
The buyer's verdict is on the basket — did everything fit, did the quality hold up for the price, was anything disappointing. A single weak item in a nine-item order colours the whole thing, which is another reason the returns filter matters: partial returns are the norm here, not the exception.
At this price point, expectations are the review
Nobody reviewing value fashion is comparing it to a designer garment. They are asking whether it was good for the money, and reviews in this category are remarkably fair about that — buyers routinely write "for the price, excellent", which is worth more to your conversion than a grudging five stars would be.
This is why asking honestly, with nothing offered in return, works better here than anywhere. You do not need a glowing review. You need a fair one, at volume, and fair is what people give when nobody is buying their opinion.
What Merita does
We watch every Kiabi order for delivery, exclude anything with a return, refund or complaint including partial returns, and send one message in the buyer's language through the marketplace's own buyer messaging. One per order. At three thousand orders a month that is three thousand asks you were never going to make by hand.
