class GmailApp method .sendEmail()

GmailApp is the Apps Script service.

.sendEmail() is the method name you will see after a dot in your code.

What it does

Sends an email from the user's Gmail account.

Why it's used

  • Email a finished report or alert straight from a spreadsheet button.
  • Notify the team when a trigger spots a threshold breach.

Common errors

  • Forgetting parentheses on sendEmail. Write GmailApp.sendEmail(), not GmailApp.sendEmail or sendEmail by itself.
  • Skipping dots between chained calls. Each step needs a dot, like GmailApp.search('label:inbox').sendEmail().
  • Adding spaces where they do not belong. Write GmailApp.sendEmail(), not GmailApp .sendEmail(), GmailApp.sendEmail (), or GmailApp . sendEmail().
  • Wrong capitalization. Use GmailApp and sendEmail, not gmailapp or sendemail.
