You can now draft an email in Google Docs and send it to Gmail
 

Google might come to your rescue the next time you need to write a carefully-worded email. The company is rolling out a Google Docs update that lets Workspace and legacy G Suite users collaborate on Gmail drafts. Open the email draft template (Insert > Building Blocks > Email draft) and your colleagues can comment or make suggestions. You won't always need to know recipients' email addresses, either, as you can mention people by name.
