How do I segment customers for marketing?

If you navigate to the Marketing tab in the sidebar and click into Lists & Segments, you'll find two ways to group customers: Lists (static groups manually curated or imported) and Segments (dynamic, filtered by customer attributes and activity). Segments update automatically as customer activity changes. Once you have lists and segments set up, they become the audience for email campaigns configured from the Marketing tab. Campaigns are built with reusable Templates for consistent branding, and customisable to match your branding.
