Everyone learns the categories to get templates approved. Fewer work through what the price gap implies for how messaging should be structured in the first place.
The design implication
Because Utility costs meaningfully less than Marketing in every market, the volume you can afford differs by category. A utility sequence on every order is comfortably affordable at scale. The same volume of marketing is not, for most businesses.
That should push you toward a particular shape: rich, useful transactional messaging on every order, and marketing that is less frequent and better targeted. Which happens to be exactly the shape customers prefer, and the one that protects your quality rating.
The false economy
Filing marketing content as Utility to capture the lower rate fails in three ways: rejection at review, recategorisation so you pay the Marketing rate anyway, or approval followed by complaints from people who consented only to order updates. The third is the expensive one, because a damaged quality rating costs far more than the rate difference ever saved.
Splitting is usually right
Consider a dispatch notification with a promotional line attached. As one Marketing message it costs the higher rate on every order you ship — including to customers who never opted into marketing at all.
Split into a clean Utility dispatch notice to everyone, plus a separate Marketing message to the subset who consented, and you pay the higher rate only on that subset. You send two conversations rather than one, and for most businesses the arithmetic still favours splitting — before counting the compliance and quality benefits.
Where the boundary genuinely sits
- Order, delivery, payment and account status — Utility.
- Appointment reminders with no upsell — Utility.
- Abandoned cart — Marketing, always.
- Feedback request tied to a specific order, no incentive — usually Utility.
- Anything with a discount code, however small — Marketing.
- Re-engagement of a dormant customer — Marketing.
Authentication is its own thing
Cheaper again, and narrow: verification codes only. Some markets have specific authentication pricing arrangements worth understanding if you send codes at volume. Do not be tempted to attach anything else to these messages — beyond the approval problem, it is poor security practice to train customers to read anything but a code in that context.
Reviewing your mix
Pull last month's conversations by category. Two questions:
- Is anything filed as Marketing that is genuinely transactional and could be cleaned up? A single promotional sentence in an otherwise utility sequence is the usual culprit.
- Is anything filed as Utility that a reviewer would call Marketing? Better to find that yourself than to be recategorised.
Most businesses find at least one message in each direction, and fixing both is an afternoon's work with a permanent effect on the monthly bill.
