A mail group is a list of several email accounts that are grouped together under one email address. This feature enables sending one message to multiple email addresses at once.
For example, if you want to send the same message to five people in the technical support department, you can create a "Support" email group that includes the individual email addresses for all five staff members. When someone sends an email message to mail group "Support", the copies of that email message will go to all five individuals email addresses. The sender does not need to know the addresses for all five individuals, just the group name. Essentially, mail groups help save time and effort.
