Three ways to email a Google Doc, and when to use each one. Send it straight from Google Docs, attach it as a PDF or Word file, or just share a link.
What's covered:
Emailing the doc from inside Google Docs
Sending it as a PDF or Word attachment
Downloading first, then attaching it yourself
Sharing a view-only or edit link instead
Pick whichever one fits what the other person needs to do with it.
