Compose new message - how to select all email address from address book ?

[langfyer]

I have been searching around, and still couldn't find an answer.  Hope someone would help. Thanks in advance.

I'm looking for a way to select all the email address from the address book.  The purpose is to send email to all my customer in 1 time.

there are 2 ways you can do it. Either you goto the compose screen and just start typing a name from your address book and a little auto complete box pops up for you to select from. Or you goto the address book, select the people you want to send the email too and then press "compose mail to" (thrid icon)
