Broadcast or transactional messaging — which should an F&B venue use?

Every dominant messaging platform in Southeast Asia offers a version of the same two products, whatever the branding: a broadcast channel to people who have followed your business account, and a transactional template channel that delivers to a phone number for a per-message fee. Operators habitually pick one and use it for everything, which wastes money in one direction or reach in the other.

Broadcast is cheap and constrained. It costs little or nothing per send, but it only reaches followers — typically a fraction of your customer base — and platforms usually cap how often you can broadcast. Delivery is best-effort: the message lands in a business folder that many users check occasionally. That makes it right for content where timing is soft: a new seasonal menu, an opening-hours change, a general promotion.

Transactional templates are expensive and reliable. You pay per message, the content must fit an approved template, and in exchange the message reaches anyone whose number you hold, arrives in the primary conversation surface, and is effectively guaranteed delivery. That combination is what you want for anything with a deadline attached: booking confirmations, a reward expiring in 48 hours, a win-back with a dated offer.

The allocation rule that keeps costs sane: transactional sends must be individually triggered. One customer, one behavioural reason, one message. The moment a venue starts blasting a transactional template to a five-thousand-person list, the cost per acquired visit becomes indefensible — and because delivery is guaranteed, the annoyance is guaranteed too. Broadcast is where list-level communication belongs precisely because it is opt-in and low-cost.

A practical stack: broadcast weekly at most, to followers, for news. Transactional for four triggers only — booking confirmation, near-reward nudge, reward expiry, and cadence-based win-back. Then push followers acquisition at the counter, because every customer converted from transactional-only to follower reduces your ongoing message cost.

Measure both channels the same way: revenue per message sent, not open rate. Open rate flatters transactional messages, which are opened almost by definition. Revenue per message is the number that tells you whether a paid send should have been a free one.
