Four Sardarshahr audiences, four kinds of message
An applicant to a teacher-training course, a family visiting the Balaji temple, a buyer of wood products and a traveller on SH-7 each get the same few kinds of message. Select a cell to see which is a reply, which a utility template and which needs an opt-in.
The first column is nearly always a conversation the other person started, so nothing in it needs a template. The middle columns are the messages a Sardarshahr college, dharamshala or workshop sends on its own about something already booked or bought, and the last column is the only one that needs a recorded opt-in.
The 24-hour service window explains when a reply needs no template.
