the easiest way to do this, in my opinion, is to create a group in your address book and add all your people to it.
Then, when you address your email, just select that group and everyone will get it.

Tip: To be a nice person, address the email to yourself and BCC the group.

That way you do not share email addresses of everyone you know to everyone you know. Some folks do not want their email address share randomly.

Hope this helps you publish your Gmail address
