Question re iCloud and personalized e-mail address.
I have set up a new personal e-mail address on icloud+ using a recently purchased domain name, as explained here Use Custom Email Domain with iCloud Mail - Apple Support (CA)
But I was trying to understand why my personal e-mail address attached to this new domain doesn't have its own inbox, eg to show up in the Mail app on my mac. I did a workaround to automatically forward to folders but these are nested under the umbrella of my appleid account. In searching for an answer, I found the steps set out by Darby Brown here Apple Mail: Custom domain email sending/r… - Apple Community, which looks like the same workaround I did.
But why is there no in box for this personal e-mail, rather, it uses the inbox of my main apple id.
Thanks in advance for any light you can share.
