Google-App-Script-Send-Email-Service-Account

This script allows you to send emails using Google App Script and a domain-wide delegation service account so that the email can come from someone else in your organization rather than just the person who is executing the script. I found this extremely valuable when I am the one setting up automation and triggers but I want them to come from specific people other than myself.

It is required that you create a service account with the proper scopes and to put the credentials from the JSON into the script.

Creating Service Account:
