What is a journey?
A customer journey is the complete series of experiences that your customers go through during their lifecycle and includes all of their interactions with your brand - from browsing to purchase to post-purchase. It is very important to understand each stage of the customer journey so you can evaluate whether you engage them with the right channel at that stage, with the right message and content.
