What 30 days of marketplace customer messages look like: one UK seller, 10 August to 9 September 2026
255 customer conversations, 655 operator notices, 1,763 orders, 112 refunds. Week by week, marketplace by marketplace, reason by reason, hour by hour. The first of a monthly field note.
Between 10 August and 9 September 2026 one UK furniture seller had 255 customer conversations across five Mirakl marketplaces, plus 655 operator notices, from 1,763 orders. The busiest week was the one after the August bank holiday, with 77 new conversations, twice the volume of four weeks earlier.
How many messages, and from where?
Operator notices outnumbered customer conversations two and a half to one: 655 notices, almost all Argos case alerts. A person reading the raw inbox spent most of their time on items no customer wrote.
Which week was the worst?
What did customers write about?
When did they write?
A third of the month's messages arrived while the marketplace clock was paused and the customer's patience was not. How the clocks pause.
What did it cost?
112 orders had a refund in the period, £8,223 in total across the five marketplaces, about 6% of orders. The reasons the operators recorded most often were “customer changed mind” on B&Q and “item returned” on Argos; damaged items were the next group. What one refund costs beyond the amount.
What do the numbers point at?
- Argos case alerts need their own list. Five notices per customer conversation means the Monday customer list should be about 20 items, not 120.
- The two faulty-item leaders are packaging questions. Faulty and missing-parts reasons on the same large flat-pack products, with customer photos attached, are what a packaging supplier needs to see.
- The evening and weekend window is a third of the month. An acknowledgement that says when a person will reply, capped per run, covers it without a night shift.
Next month's note will show whether the faulty-item count moves. Which orders generate messages explains the product cut behind it.
- 255 conversations, 655 notices, 1,763 orders: one conversation per seven orders.
- The week after the August bank holiday doubled the volume of four weeks earlier.
- A third delivery, a third product; peak hour 15:00, a third after hours or at the weekend.
- 112 refunds, £8,223, about 6% of orders.
Questions people ask
Is one conversation per seven orders normal?
For bulky, delivered furniture on UK marketplaces it is in the usual range. Smaller items shipped by parcel carrier run lower; anything above one in five points at a product or carrier problem.
Why do operator notices matter if they are not customers?
They carry a deadline, and they crowd out the real messages. On Argos they were five for every customer conversation, so an inbox that does not separate them makes the team slower on both.
Where do these numbers come from?
From the seller's Growstall workspace: messages and orders read through each marketplace's API, classified once per conversation from the customer's first message, and counted on the day the customer wrote.
