iCloud Mail
When you set up your iCloud account, you will get a free "@icloud.com" email account.
The push notification feature is available for iCloud Mail, so your iPhone will immediately receive a push notification to alert you of a new message coming in. Since, of course, your iCloud Mail will be synced across all your iOS devices through iCloud, when you check your email, the same messages will be displaed on all your devices.
