I'm afraid that this isn't possible. (At least, not right now.)
A quick perusal of the Google Drive support forums shows other people also wanting to have more dynamic mailto:
links in their Google Documents. (Surprisingly, this might be easier to do with Google Spreadsheets and the =hyperlink()
function.)
Anyway, I did some experimentation.
A mailto:
link with one Email address will work.
mailto:bigal@example.com
However, it has to be an email address. Using a name (so that Outlook will search for it in your address book) doesn't work.
I also tried a couple of other tricks to get multiple addresses in the link.
mailto:bigal@example.com?cc=littlejohn@example.com
That doesn't work. Nor did separating email addresses with commas instead of semi-colons, so that's not an issue.
So, it appears that in a Google Document you're limited to the very simplest mailto:
link.
Assuming you're "locked in" to the Google eco-system, your options at this point are to either put email addresses into the document as plain text (so people can copy-paste directly to their email client compose window) or create an email alias for each group of people who should receive email messages from a document. (That last is certainly impractical for even small shops.)
Best Answer
You can create a bookmark.
Place the cursor where you want to link to, and select Insert → Bookmark from the menu.
Click the Link item in the popup menu:
The browser location bar now shows the URL to the bookmark, which you can forward to other users (that have access to the document, of course).
