Mailchimp Integration with Square Marketing

[#1]

Hello! I have a Mailchimp account with an established set of templates and email lists, and I have a Square online website with its own customer list. 

is there a way to integrate Mailchimp into Square Marketing so customers are imported directly into Mailchimp when they make a payment on my online store? I’m entering new customers manually into Mailchimp right now and would like to automate this process. 

I also want to be able to send order confirmations and other automated emails from mail chimp instead of my square account. 

is this possible? Thank you!
