iCloud: Mail overview
You can send, receive, and organize email by using the Mail app on iCloud.com from a Mac or Windows web browser. New mail you send and changes you make to your inbox and folders are automatically pushed to devices you set up for iCloud Mail. On your iOS devices and Mac computers, changes are pushed to the Mail app, and on your Windows computer, changes are pushed to Microsoft Outlook. No matter which device you use to send, receive, or organize email, the changes are updated everywhere, so you never have to connect your iOS device to your computer to keep your inbox and mail folders current.
Use iCloud Mail from a web browser
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 see and use 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.
