Create a new contact.
Name the contact something pertinent to your mass mailings like "Loving Contributors", "Band Fans", etc. Put your email address in the email field and save the contact. 

Create your email message
In the TO field select the contact record you just created.  Then put all the addresses you want to send message to in the BCC field. (Blind Carbon Copy).  This way your recipients will not get a big long list of email addresses the email was sent to. It is much more professional and you will receive a copy of the message also. If you can't see the BCC field click on View and make sure the BCC Field is checked.
