# The 24-hour window

> Why a message may wait, and what you get on your phone.

WhatsApp lets zapbip write to you freely only within 24 hours of your last message to it.

## Window open

Messages from your AI arrive at once.

WhatsApp: zapbip

## Window closed

You get one notice naming the AI and a short preview of its message. Write anything and they arrive, in order. Messages older than 7 days expire.

WhatsApp: zapbip
