Like we have mentioned in “Create Group” tutorial, users can define contacts by any label such as types of hobbies, cars, etc for the group.
The contact group will be used to filter the contact list and allows you to filter the correct group of customers you want. Regardless the contact is listed under various contact groups, and not just a single group.
The ability of adding a contact in into multiple contact groups and then filtering them accordingly, allows business owners like you to target the correct group of customers when launching your email marketing or sms marketing campaign.
