If you assign categories to Contacts, you can send an email message to everyone in the category.
To do this in Outlook 2010, begin by grouping by category then select the category and click the Email button on the Home ribbon's Communicate section. This will open a new email message addressed to the members of the category.
The steps are similar in older versions: group by category, select the category group then use the Actions, New message to contact command to open a new message addressed to the category members. In Outlook 2007, look for the New message to contact command on the Actions, Create menu.
