You can't add an iCloud alias email address as a separate account.
When addressing an email, you can select From: in the message header and your iCloud alias email address or addresses will be available to select to send the email from.
All email received by your alias email address will be delivered to the Inbox mailbox for your main iCloud email account.
When replying to an email sent to your alias email address, the alias email address will be selected as the sending email address automatically.
I know you're up things with Apple, but this one stumps me. Iv tried for 2 months to add an alias to my iCloud main address, but it won't do it.
Iv an account back to the @mac.com days. Which stayed, but added @me.com and @icloud.com as time past. In the old days you went to the new iCloud.com account site, preferences and added an alias that way. Now you have to access AppleID@apple.com, but that site will not allow me to add an alias.
Even the help section on iCloud provides the old information to adding an alias. Except that does not exist on the iCloud page any longer.
Create an email alias
- In iCloud Mail, choose Preferences from the Action pop-up menu in the sidebar.
- Click Accounts.
- Click “Add an alias.”
- Provide the requested information:
- Alias: The text you provide becomes the email address (email@example.com). An alias must contain between 3 and 20 characters.
- Full Name: The name you provide appears in the From field of the recipient’s email.
- Label: iCloud Mail uses the label to categorize messages sent to your account.
- Label Color: Messages appear in your Inbox with the colored label that you specify.
- Click OK, then click Done.
