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 your iOS devices and computers that are 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.
iCloud also keeps Mail rules, signatures, flag names, and Smart Mailboxes up to date on your iOS devices with iOS 6 or later, your Mac with OS X v10.8 or later, and iCloud Mail. If your iOS devices and Mac computers are also set up for iCloud Contacts, iCloud keeps your Mail VIP senders and recent recipients list up to date on those devices.
When you set up iCloud with a new Apple ID that doesn’t use an existing email address, your new Apple ID ends with @icloud.com and is the email address for your free iCloud Mail account. 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.
If you already use iCloud Mail with an @mac.com or @me.com email address, you also have an @icloud.com email address. You have an @icloud.com equivalent for every active @me.com or @mac.com email address or alias that you have as part of your account.
After you set up your iCloud Mail account, you can sign in to Set up iCloud Mail on your devices.
Access iCloud Mail from a web browser
Go to Apple ID (the one you use with iCloud) or your @icloud.com email address (not an alias).
If youʼre using another iCloud app, click the app’s name at the top of the iCloud.com window, then click Mail.
When accessing iCloud Mail, make sure you use a browser recommended in the Apple Support article iCloud: System requirements.
