# How can I use my customer data

By syncing customer purchase data from Stripe using Data Mapper for Mailchimp, you can get a much more detailed overview of your customers.\
\
To start, you’ll want to segment your audience into smaller groups based on what’s important to you.\
\
For example, you could segment customers who’ve spent over $400 in your store.\
To do this:

* Open up your [Mailchimp audience](https://us20.admin.mailchimp.com/audience/contacts/)
* On the right click “Create new segment”
* Click either Regular or Advanced
* Choose a filter and scroll down to the “Ecommerce Activity” group
* Select “Amount spent in total”
* Add “400” to the currency box (it should read “Amount spent in total more than $400 USD”)
* Select “Preview segment”
* If you’re happy with your segment, select “Save as segment” and give it a name

You can use the above steps to create segments for whatever grouping you like, giving you a refined audience.\
\
Once you’ve segmented your audience, you can then use the segment to send campaigns to the customers on that list, allowing you to create hyper-focused messaging for those customers.
