I learn in a school, where a large portion of the students don't use smartphones (because of addictions, pornography, and so on).
My classmates and I have a WhatsApp group, and sometimes we send important messages, which the smartphone-less students don't know about.
Is it possible to have a code that you write at the start of an important message (something like "important message" or emojis that nobody uses like 🈚), and the message will be copied and sent to the smartphone-less guys?
