Organizing your contacts by groups allows you to categorize them for follow-up purposes. You can create new groups by following the next steps:
Sign into your backoffice at https://www.enagicwebsystem.com/backoffice.php
On the left navigation column, click on Marketing System > Contact Manager. Then Click on Manage Groups at the top menu.
Type the name of the group you want to create on the "Add new group" box and click on Go.
In order to assign contacts to that group, just go back to your contact list and right click on the contacts name > groups > add to groups.
Note: You can also highlight several contacts and send them to one group at the same time.
