Is there an easy way to send a mass mail to all your contacts ? Personal or otherwise without having to create a contact group or special contact list ?

This is basic functionality in most email clients , but I can't seem to find anywhere how this would be done on ZCS5.

I know you can setup a contact group and specific contact lists, but then I have to constantly update those lists when I add new contacts throughout the week.

To be clear I'm looking for the ability to just create a new email and easily send to all my contacts.

Ideas ?
