The right message, the right channel, once

School communication usually fails through inconsistency rather than silence. The absence alert that went out for 7A but not 7B; the fee reminder one clerk sends daily and another never sends; the same announcement texted three times. Temari routes every notice through one pipeline: an event happens in the records, the pipeline decides the channels by policy, and the message renders per recipient.

Because notices originate from events rather than memory, coverage is total by construction: every absence, every due invoice, every released result produces its notice, school-wide, without a human remembering. And because the pipeline deduplicates, a repeated event folds into one message instead of a barrage, which is the difference between a channel families read and one they mute.

Everything lands in the in-app feed always; SMS and email go out for the events that deserve them, with genuinely urgent notices piercing any mute. Each notification deep-links to the exact screen it is about: the invoice, the register, the result, rather than a homepage.

In an Ethiopian school, the same classroom holds families who read different languages, sometimes more than one under the same roof. Temari stores one language preference per person and renders every message at delivery time in the reader's language: the same absence reaches the mother in hers and the uncle who pays the fees in his.

This goes past interface chrome to the message bodies themselves, professionally written per event for every language the platform carries, including the SMS texts that reach feature phones. A grandmother with a ten-year-old Nokia gets school news in the language she reads, which is the entire point of a school communication system in this country.

Message templates extend the same idea to human-written text: schools curate reusable tri-language templates for the communication book, such as "please come for a meeting", "homework not submitted", and the family receives the template resolved in their language, whatever language the teacher typed in.

Free-for-all messaging between staff and parents is a liability no Ethiopian school wants; silence is a failure no parent accepts. Temari's chat holds the line between them. Staff rooms and section channels organise internal talk; each student gets one family thread, so a parent's relationship with the school is one conversation, not five teachers' personal numbers.

The communication book gate is the distinctive piece: schools can require that a teacher's message to a family pass homeroom or director approval before it sends, and can require teachers to use the curated templates or merely suggest them. The school's voice to families stays deliberate and on the record.

Everything is auditable, because conversations belong to the school rather than to private phones. When a teacher leaves, the family thread and its history stay behind, and no parent had to be handed a teacher's personal Telegram in the first place.
