Two audiences: families choosing, families enrolled
A school's WhatsApp does two different jobs. For families still choosing, it is an admissions desk: fees, curriculum, transport, seats left in a grade, visit times. For families already enrolled, it is a notice board and an accounts office. The two need different flows, different templates and often different people answering.
Institutes and training centres have the same split on a shorter cycle. Someone asks about an English course or an accounting diploma this week, wants to start next month, and then needs session reminders, schedule changes and a certificate notice.
One rule applies to all of it: messages about a student go to a parent or guardian, never to the child's own number, and each parent chooses the language they receive.
