Hi @tayloracademyofmusic!
Did Troy’s suggestion help? Do you use a scheduling app like calendly?
If not you can do this using Google Calendar using the Google Calendar New Event, or New Event matching search if you only want certain events to trigger the Zap. When you set up those triggers, you care given the option to trigger the Zap a certain amount of time before the event start, which means you can trigger the Zap 1 day before the event. To send the email reminder, that will depend on how the events are currently set up. If the students are attendees on the event, you can get their email address that way.
Does that help to get you started? If that doesn’t work for you could you share some more information about the apps that you currently use? What calendar/scheduling app do you use to record the lessons? What information is on the lesson appointment? And how do you store student information, a CRM, a spreadsheet? If we know a bit more about how you’d like to do things we can offer some suggestions
