Emails designed and connected Shopify/appointio scheduling and square

I am looking for 3 emails to be designed, 1 to be sent out when a customer makes an online booking through our Shopify store with a welcome and details on the email for the time and date for their appointment and also a way for them to reschedule if needed. A second email for an abandoned cart in Shopify if they have entered their email but not completed the transaction. A third email to be sent out when they make a purchase offline via our square pos, it will be an email with a warm welcome and detailing the products purchased and how to reorder.
