The more customers your Shopify store has, the more valuable customer segmenting can be.
But even new and small stores can benefit from segmenting...
...when you segment your customers from your non-customers.
Both groups have a major difference in behavior, one bought from you and the other hasn't. That one behavior is a strong indicator of other future behavior (e.g. repeat purchases, customer service contact).
While you can use an app like Repeat Customer Insights to segment them, you can also do the basics yourself. e.g. for email marketing send each customer who orders to a different mailing list campaign.
Both groups should get your marketing, but your customer group should get the better deals and more frequent content.
If this sounds simple, it's because it is. Marketing doesn't have to be complicated.
