Start by going to Audience → Segments or by clicking here to get to the overview with all your saved segments. The Create template button is then found to the right.

When it's time to choose a template, you get to choose between ready-made templates or start from scratch with a Blank one.

Ready-made templates will already have a defining filter for the target group, a name, and a description, but you can modify and edit all of them in the next step if you'd like.

In this step, you start with a name, a description, and an avatar for your segment.

Then, it's time to customize the filter to target the contacts you want to isolate.

The most common filters for segments are the categories found under the Include and Exclude block. They give you the following categories to add to your segments:

Subscribers can be used if you have a certain subscription type that you want to base a segment on. For example, if you have a list of all your subscribers who actively signed up for news from you and want to create a segment to target all of them who haven't made a purchase yet.

When you feel ready, click on Save, and the statistics will start to generate.
