Once you have the contacts on your mailing list, you can divide them, according to your needs, into different groups.

Just go to Contacts >> Show Contacts >>click on Show Advanced Settings and choose the parameter your would like your group to fulfill (it can be a particular sign-up date range, a domain name in an email address, or a custom variable - if you are using them).

Please do not put check marks next to contacts' names as the system saves all the contacts that are displayed.

Once you have the search results displayed, you will see the tool for creating groups in the bottom of the page.
