Every school system has an official communication platform. Most schools have two or three of them. What they have in common: they reach the families who are already engaged. The parents who know how to navigate the portal, who check their notifications, who read the school email.
They don't reliably reach the families who need to hear from you most.
First-generation families. Multilingual households. Parents working multiple jobs who aren't monitoring apps between shifts. These families aren't disengaged from their children's education; they're disengaged from platforms. For many of them, a letter that arrives at home is the only school communication that registers as official.
Physical school communications don't require an account login, a remembered password, a notification setting that hasn't been disabled. They require a mailbox. And they stay — on the counter, on the fridge, in the drawer where important papers go — in a way that portal notifications simply don't.
