Google is enhancing the way you work with Google Workspace Add-ons in Gmail with the addition of Compose-time functions. Compose-time functions can help modify and format your messages in Gmail faster by:
  • Adding recipients in the “To”, “CC”, and “BCC” fields.
  • Inserting content into the subject line and body of the email.
  • Inserting message templates for a consistent look and feel for your communications, and more.
