How to send registration email after purchase?

Was wondering how I can have an email sent to the customer after they purchase so that they can create a username and password to log into the members area. Or is it possible to have them create the password during checkout?

Using Stripe for payments and Drip as the email provider. I set up Drip automation so that after checkout is complete and a new member is created, it will add them to a Drip campaign with a “paid member” tag.

Also, my domain is hosted on Cloudways, but my domain email is still hosted on Hostgator.
