One stream, every kind of work #
Open a typical sales@ mailbox on a Tuesday morning and the messages will include orders, amendments to orders sent an hour later, stock questions, price requests, quote chases, proof of delivery requests from an accounts department, invoice queries, credit note chases, a new account application, three supplier emails and a lot of marketing.
They are not labelled. They are interleaved. And several of them are replies to threads that started weeks ago with a different member of staff.
There were about 101,000 wholesale businesses registered for VAT or PAYE in the UK in March 2025. The overwhelming majority are small enough that this mailbox is watched by two or three people, all of whom have another job.
Why sorting costs more than answering #
Answering a stock question takes a minute. Working out that a message is a stock question, which customer sent it, which depot it relates to and whether somebody has already replied takes longer, and it happens for every message, including the ones that need no action at all.
Worse, the sort is not durable. Nothing records that a message was classified, so when the next person opens the mailbox they start again from the top. Three people watching one mailbox means the same triage done three times, plus the risk of two replies to the same customer and the risk of none.
The common workarounds all have the same flaw
- Folders depend on discipline
- Flags and read status are shared and get clobbered
- A rule that files by sender breaks when a customer emails from a different address
Which parts run on rules #
Runs on rules
- Classifying a message by type: order, query, price, POD, invoice, account
- Identifying the customer account, even when the address is new
- Recognising it as a reply to an existing thread or order
- Routing it to the right queue and marking it as handled
- Acknowledging receipt so the customer stops chasing
- Answering the small set of questions that are pure lookups
Needs a person
- Judging that a customer is about to leave and needs a call
- Deciding what to concede in a dispute
- Anything involving a commercial exception
The evidence problem hiding in the mailbox #
A shared inbox is also, by accident, the company's record. When an argument starts about what was ordered, what was agreed or what was delivered, the answer is usually in a mail thread rather than in the order system. That is fragile. People leave, mailboxes are archived, and a message that lives only in an inbox is not really filed.
It matters because the underlying records have a statutory life. HMRC guidance says VAT records must generally be kept for at least 6 years.
What to look at first #
Take one week and count the messages that land in the main sales mailbox, then classify them by type by hand. Two numbers usually come out of that exercise and change the conversation.
-
The share of messages that are one of five or six repeating types
Usually most of them.
-
The share that need a decision rather than a lookup
Usually small.
Then look at what the sorting costs: how many times a day does somebody read the whole mailbox top to bottom? In most depots the answer is three or four, by different people.
The largest single category is normally orders, covered in taking orders by phone and email, and the most repetitive queries in stock and availability questions. The free tools will convert the message counts into hours.
