What is a list segment?
You might be wondering what we mean by a list segment. In essence, list segments are dynamic saved searches that you can return to at a later time.
For example, if you create a list segment for everyone who has a VIP tag and donated more than $150 since January of 2015, you'll be able to save that search; and as more people donate and get tagged as a VIP, that list segment will grow to reflect the new people who meet your conditions the next time you return to it.
Once you've created a list segment, you can return to it trough the people menu at the top of Artful.ly.
