Hi there, @Alex_Joseph !
Thank you for your post. As @IP1999 mentioned, the current options for email hosting with your Shopify domain are Zoho Mail and Google Workspace. Another option you may want to consider is setting up email forwarding!
Email forwarding is a service that enables you to direct an email message that’s sent to one email address to another email address. With your Shopify-managed domain, then you can set up an unlimited number of custom domain email addresses that forward to an email account hosted by a third-party. This is a great free option that is used by many merchants. If you’d like to learn more, you can check out our help document here.
Please let me know if you have any other questions!
