Often you need to include something in an email, even if you are already sharing files in Google Apps. With Gmail you can attach a document from your computer, Google Drive or from a web link. You can also insert calendar invites for easy event replies.
Hover over the paperclip icon on the bottom of the message to show options for attaching a file; inserting a picture, document, emoticon, or calendar invite; or creating a hyperlink.
To attach a file, click the paperclip and then browse for the file on your computer or local network. Once attached, the file appears at the bottom of the message. To remove an attachment, just click the x.
You can also attach files by dragging and dropping them into the body of the email. The files will attach at the bottom of the email.
To embed an image in your email, you can click the Insert photos icon and browse for the file or, if you have Chrome, drag a single file and drop it into the body of the message. It doesn’t matter where you drop your image, the file will position itself where you last clicked in the message.
Insert a calendar invitation
Insert a calendar invitation into your email by clicking the Insert invitation icon and filling out the fields. The invitation will be sent to everyone copied on the message.
