I would like two email lists to send separate mails to. How can I split or build a different email list.?

I need separate email lists so I can send mailings to former classmates for class reunion without having to send to my entire email list or adding classmates and checking everyone else off.I would like two email lists to send separate mails to. How can I split or build a different email list.?
Create mailing lists:


1. click on ';contacts'; on the left


2. click on ';Add List';


3. give your list a name for later reference


4. type the name of a contact you want to add to the list in the text input field and click ';Add Contact to List';


5. repeat step 4 for every contact you want to add


6. click ';Save'; when you're done to add the list to your contacts





Next time you want to send a mail to everyone in that list, click the list name in your contacts and it will start a new E-mail message for you.
