To create a mail group in First Class, open your Contacts by either double clicking on the Rolodex icon on your First Class desktop or clicking on Contacts in the left margin (see screen shot). Click on the arrow next to "New" and choose New Mail List in the drop-down menu. When the little box pops up, enter a name for your mail group and type the names of the members you want in this group. Click OK to save this group. When you're ready to compose an email to this group, simply type the name of the group in the "To:" field of your email.
