Setting Up Email Addresses with Beehiiv: A Guide

Hi beehiiv support. I have a question about how to set up an email service with beehiiv. I connected my domain to beehiiv and the email address such as hi@example.com is used for sending out the newsletters. What if I need to set up other email address to receive emails from my users? such as support@example.com. I've checked some business email service, and if I move my DNS records such as MX to them, I don't think beehiiv will using the domain as sender? I get confused here
