A segment is a group of contacts defined by a set of conditions. Unlike a static subscriber list, segments are dynamic, meaning they grow as contacts meet the segment's conditions and shrink as contacts no longer meet them. Segmented email sends often return more revenue per recipient than unsegmented sends since they can be tailored to a particular situation, and thus are more relevant to the recipients. Privy offers two kinds of segments: 1. Custom Segments 2. Smart Segments Check out the following guide on how to build, manage, and use your segments in Privy. ## Custom Segments Custom Segments are built from scratch by you! You can customize a group of your subscribers by combining a number of filters and criteria such as Shopping Activity, Email Engagement, Website Activity, and Customer Attributes. ### Create a new segment To create a new segment: * Head to [Contacts > Segments](https://dashboard.privy.com/segments) in your dashboard. * Click **Create Segment** in the upper right to access the segment builder. Now you're ready to build your segment: * Name your segment. This is internal only — your contacts will not see this name. * Select whether you want your contacts to **Match all** criteria or **Match any** criteria. * Click the **Choose Category** menu to start selecting your conditions for your segment. * To add more conditions, select the **+ And** or the **+ Or** buttons to start selecting the next condition. * The contact count will adjust as you add filter(s). Once you're happy with your segment, click **Create.** Screenshot pointing out how to create a Custom Segment ### Segment Conditions Privy offers a number of different conditions to segment your audience by.
