I have a domain at a 3rd party and I’m using Minimal theme. I’ve added the 4 CNAME and the TXT record as suggested, everything looks fine. I just have no idea where I’m supposed to find my incoming emails. I also installed Shopify Inbox but that seems to deal with chats (which is working).
The sender email address is located under the Notifications settings, and it looks like you may also need to add Shopify’s DMARC record by authenticating your third-party domain. If you need help with this, then we’ve got a step-by-step guide right over here: Change your sender email.
If you have any other questions, then don’t hesitate to let us know!
