Ever thought about sending calendar-scheduled, automated messages using your Google email? With Google Apps Script, you can turn any calendar event into a trigger that sends personalized emails—perfect for reminders, confirmations, welcome notes, partner updates, ops alerts, and more.

What this project is

A lightweight automation that turns Google Calendar into a messaging surface. Create or update an event; the script picks up recipients, subject, and message from the Description, then sends a clean HTML email (optionally with an inline Drive image). No servers, no cron boxes—just your calendar.

👉 Code & setup: GitHub repo

What you get (outcomes)

• Hands-off messaging tied to dates you already manage.
• Human-friendly config: change recipients/content in the event itself.
• Idempotency: safe daily runs with duplicate protection.
• Brand-ready emails: optional inline image from Drive.

Why it’s useful (in practice)

• Operational nudges, partner follow-ups, internal reminders—all where scheduling already lives.
• Reduces context switching and “forgot to send that email” failures.
• Scales without extra infrastructure; respects Gmail/Apps Script quotas.

How it works (technology, briefly)

• Optional time-driven trigger (e.g., daily at 08:00).
• Google Apps Script (V8, JavaScript)
• CalendarApp to read events; MailApp to send HTML emails; DriveApp for an inline image.
• PropertiesService stores a “sent today” flag per event → prevents duplicates.

Let your schedule send the message—set it once, get back to building.
