How can I get into my iCloud email

sorry, I missed you are on IOS, or not ?

1. Using any supported web browser, you can use iCloud Drive at iCloud.com.
2. On your Mac, you can go to iCloud Drive in Finder.
3. On your iPhone, iPad, or iPod touch with iOS 11 or later, you can access your files from the Files app.
