iCloud email creation
Hi there,
I'm thinking of creating an iCloud email address. Currently my apple ID is used with a third party email, and I'd like to keep it that way. I do not currently have an iCloud email. I'm looking to set this up with mac os (system preferences > apple ID > iCloud left hand pane > tick "Mail" box > prompt to create iCloud email), and currently in Mail, my different third party emails work well separately. I'm worried that a) once I create this iCloud email, i will then need to change my apple ID to this, and in turn change all my logins that use Apple ID. and b) I don't want all my emails to merge into this one iCloud email on Mail or on my other devices. Are either of these two scenarios a possibility, and is there anything else i need to be aware of? I like the way everything is set up currently, hence my worry. (images to help) thanks!
