What 20 months of a real POD store’s support inbox looks like.
We ran every one of the 28,288 emails that hit one print-on-demand store’s support inbox between April 2024 and December 2025 through a measured, two-stage classification pass - deterministic rules first, then a single model pass on what survived. No sampling, no extrapolation, no synthetic data mixed in.
Basis for every number on this page: one POD apparel store, 28,288 emails, 2024-04-09 to 2025-12-26 (20.5 months), measured.
The mailbox nobody sees
Before you can talk about what customers ask, you have to deal with what a support inbox actually is - and most of it isn’t customers. Over half is the merchant’s own outbound mail (replies, forwards, self-sends). Add noise senders, Shopify’s own order-notification emails, and everything the classifier flagged as spam or a platform notice, and one number falls out:
91.7%
of everything that hit the support inbox was not a customer conversation. Only 8.3% of the mailbox - 2,344 emails out of 28,288 - was a real customer writing in.
Buckets sum to 100% of the 28,288-email mailbox. The first three buckets are deterministic rules; the last two come from a single classification pass over the 6,671 emails that survived those rules.
The number that matters
Strip out everything that isn’t a customer, and this store fielded 2,344 real customer emails over 20.5 months - roughly 114 a month. That’s the actual job: not 28,288 emails, not even close. It’s a couple hundred real conversations a month, buried inside a mailbox twelve times that size.
“Roughly 114 a month” is a simple derivation (2,344 ÷ 20.5 months), not an independently measured rate - treat it as directional.
What customers actually write about
For an apparel POD store, sizing beats “where is my order” as the number one reason a customer writes in. Sizing/exchange requests, WISMO, and quality claims together are 64.8% of every real customer email - the rest of the inbox is a long tail.
The single largest intent - more than WISMO.
2 threats in 20.5 months - see below.
Every one of these has a ready-to-send reply template built from this same data.
How they’re feeling when they write
Most real customer email reads calm, not upset. Anxious tone shows up more than outright anger - which tracks with the top intents above: a sizing question or a WISMO check-in is worry, not fury.
The grateful share skews high in part because thank-you replies inside an ongoing thread are counted as their own inbound email.
2 chargeback threats in 20.5 months.
Rare, but catastrophic when missed. The case for an escalation guardrail that never lets a chargeback threat slip past unnoticed isn’t volume - it’s that the two that happen in twenty months are exactly the two you can’t afford to miss.
What this means if you run a POD store solo
A couple hundred real emails a month sounds manageable until you remember they arrive mixed into a mailbox where 91.7% of it isn’t a customer at all. Finding the signal is most of the work before you’ve even written a reply - and sizing questions, WISMO check-ins, and quality claims are predictable enough that you shouldn’t be composing each one from a blank page.
That’s what the template library is for, and it’s what Podley does automatically: it reads each customer email as it lands, checks the live Shopify and Printify order, and drafts the reply in your voice, so you’re answering the 8.3% instead of triaging the rest by hand. Reaching out before a customer has to ask - proactive WISMO deflection - is a feature we’re still building, not one we’re selling yet; today Podley answers what lands, accurately and fast.
Method: a deterministic pass first buckets every email by rule (the merchant’s own outbound address, known noise senders, Shopify order-notification subjects, too-short-to-classify). Everything that survives those rules is classified once, by a single model pass, into an intent, a tone, and an order-state. Nothing verbatim from a customer email is stored, quoted, or reproduced anywhere in this report or in the templates it feeds - every figure is a count or a percentage, and every customer line elsewhere on this site is an illustrative example, not a real quote.
