iCloud How many aliases do you get with the iCloud custom domain?

[TinaBelcher]

With a regular @icloud.com domain, you get 3, with Outlook 10 and with Gmail 30...

Please, don't tell me that you're still stuck with 3 alias after purchasing a domain from Apple...


And does the notification still stay unchecked on one device if you open an email from another device?

So Apple doesn’t sell you a custom domain you need to already own that domain. I have also not seen any info about creating any type of alias for custom domains with iCloud.

Still just 3 aliases per domain. And as @hg.wells stated, Apple doesn’t sell you the domain. You get the domain from any domain registrar and set the DNS to point to Apple’s iCloud servers. Instructions are provided when you add the domain in account settings at icloud.com.

And the mail app notification badge is not in sync across devices.
