Multiple iCloud Custom Email Domains in the same inbox

Oh man I was hoping that wouldn't be the case.

I was hoping you could set the iCloud Custom Domain email as a discrete inbox, but it looks like you can't?

Anyone find a workaround elsewhere?

Hi, rob_pop.

You wouldn't be able to have separate inboxes, as that would be a feature of actual separate email accounts. custom email domains give you a personalized email address, but do not function as a separate email account (so they would not include a separate inbox). You can read more about this here: Personalize iCloud Mail with a custom email domain and share with family - Apple Support

We hope that clears things up.
