Correct Trigger to create email, SMS 24hr, 2hr and 30 mins before event? Considering costs as well? so from a 5 or 10min trigger

:bullseye: What is your goal?

Creating a solid, reliable, cost effective reminder system. I am trying via a FILTER now, which I am sure is logical. I have also read about using Google Calendar. Any feedback more up to date. thanks. Mark

Welcome to the Make community!

You can have a scenario watch new items and schedule a cron job callback using apps like 0CodeKit that allows you to schedule a “callback” to a URL defined in a “Custom Webhook” trigger in another scenario at the exact time you want

You don’t have to use a data store, this is just an example. You can use Google Sheets, Google Calendar, etc.

Alternatively, if you are already using Airtable, you can use an Airtable formula and built-in automation, briefly mentioned here.
