First, you need to log in to your Raklet account, and then on the admin panel, go to Contacts.
Decide how you want to define a selected group of members. Then, filter for that specific definition. For example, filter for “First Name is Lana”.
When you click on done, you’ll see a list of people named Lana. Then, click on Save Segment.
Enter your segment name and click "Save".
You’ve successfully created a new segment! Now, when you add a new contact named Lana, that contact will also go under this segment.
