AI-generated Key Takeaways

The Gmail service in Google Apps Script allows for comprehensive management of Gmail accounts, including sending emails, managing drafts, labels, and messages.
The GmailApp class provides access to various Gmail functionalities, such as creating drafts, managing labels, searching emails, and retrieving threads.
GmailThread and GmailMessage objects offer methods to interact with email threads and individual messages respectively, including marking them as read, starring, moving them to different folders, and replying to them.
You can use dedicated classes like GmailAttachment, GmailDraft, and GmailLabel to work with email attachments, drafts, and labels respectively.
The service offers methods to search for emails based on queries and to manage spam, starred, priority inbox, and trash threads.

This Service lets you send email, compose drafts, manage labels, mark messages and threads, and conduct a variety of other Gmail account management tasks. See also Mail Service, a simpler service that only allows the sending of email.
