Use iCloud Mail from a web browser
If your Apple ID doesn’t end with @icloud.com, @me.com, or @mac.com, you must set up an @icloud.com email address before you can use iCloud Mail on iCloud.com.
To use iCloud Mail on iCloud.com, go to icloud.com/mail and sign in using your Apple ID (the one you use with iCloud) or your @icloud.com email address (not an alias).
If you don’t see Mail on iCloud.com, your account just has access to iCloud web-only features. To gain access to iCloud Mail and other iCloud features, set up iCloud on your iOS device or Mac.
If youʼre already using another iCloud app, click the app’s name at the top of the iCloud.com window, then click Mail.
When working with iCloud Mail, make sure you use a browser recommended in the Apple Support article System requirements for iCloud.
