Your address does not change
Connect the mailbox you already have. Nothing moves, and there is no new address to learn.
Alternatives
iCloud Mail is Apple's email service, and if your address ends in icloud.com, me.com, or mac.com, that is where your mail lives. Patriot Mail opens it in a calm inbox that is easy to read, next to any other accounts you have. You keep your address, and your mail stays with Apple.
Some people have had a mac.com address since long before the iPhone. Whether yours ends in mac.com, me.com, or icloud.com, it stays exactly as it is. Patriot Mail connects the mailbox you already have, and nothing moves.
Apple keeps your main password for Apple's own apps. For any other email app, you create an app-specific password in your Apple account and use that instead. It takes a minute, the guide walks you through it, and you can remove it later from your Apple account whenever you like.
Unsubscribe from a mailing list in one tap. Block a sender, or a whole company by blocking its domain, and block as many as you like at no charge. What they send is usually deleted the moment it lands, or failing that, the next time you open the app.
Patriot Mail is free, with no subscription and no trial that ends. Your messages are not permanently stored on Patriot Mail servers, and your inbox data is not sold or used for advertising. Add Gmail, Yahoo, Outlook, and others too, and read everything in one list.
No. Patriot Mail opens your existing iCloud Mail, and your icloud.com, me.com, or mac.com address stays the same.
Apple asks for an app-specific password, a separate password you create in your Apple account just for email apps. The iCloud guide shows you where to find it.
Yes. Patriot Mail runs on the web with nothing to install, so you can read your iCloud Mail on a Windows computer too.
