iCloud: What is iCloud Mail?
With your iCloud Mail account, you can send, receive, and organize email. When you set up your devices for iCloud Mail, you can also access your iCloud Mail account using the Mail app on your iOS device or Mac computer, or using Microsoft Outlook on a Windows computer. No matter which device you use to send, receive, or organize email, the changes are updated everywhere.
To use Mail on iCloud.com, go to icloud.com/mail and sign in using your Apple ID (the one you use with iCloud).
If you have set up an @icloud.com email address, you can also use it to sign in to iCloud. If youʼre already using another iCloud app, click the app’s name at the top of the iCloud.com window, then click Mail.
If you don’t see Mail on iCloud.com, your account just has access to iCloud web-only features. To see and use iCloud Mail and other iCloud features, set up iCloud on your iOS device or Mac.
When working with iCloud Mail, make sure you use a browser recommended in the Apple Support article System requirements for iCloud.
