Attach Google Docs
As a G Suite user, you likely store PDFs, photos, and other files in your Google Drive account. You can now attach those files to a message to send to customers. It's a great way to share quotes, sketches, and proposals.
Google Drive can be attached from Chats or Lists. Just click the paperclip icon and then click on 'Google Drive'. You will see the Google Drive document picker. Select the appropriate document. You will see the name above the compose field. The recipient will receive the public link of the Google Drive file and can click it to review.
