Are the messages readable in easy-read format?

The default style comes close: short sentences, one piece of information per message, everyday vocabulary, no obscure abbreviations or decorative emojis. You can push the script further toward full easy read — the FALC method — at setup or later, per line. Appointment confirmations follow the same simple style: date, time and address spelled out in full. Honesty: it's a style convention set per line, not an official certification — but it follows the recognized rules.
