How to activate apple email on my phone

Hi smmatrix,

Thanks for posting in Apple Support Communities.

We understand that you need help with your email address on iPhone. Are you trying to add your iCloud email to your Mail app? If not, can you clarify on what you're trying to achieve?

"Set up iCloud Mail on your iPhone, iPad, or iPod touch

1. On your iPhone, iPad, or iPod touch, go to Settings > [your name] > iCloud.
2. If you want to send and receive iCloud Mail on your device, do one of the following:

• iOS 16, iPadOS 16, or later: Tap Mail, then turn on Use on this [device].
  • 
  • iOS 15, iPadOS 15, or earlier: Turn on iCloud Mail (or Mail).

If you want to keep Mail settings up to date across your devices, turn on iCloud Drive. The following settings stay up to date:

• The order of your mailboxes (for all iOS and iPadOS devices)
• Email address suggestions (for all iOS, iPadOS, and macOS devices)
• VIPs (for all iOS, iPadOS, and macOS devices)

To view your iCloud Mail, open the Mail app. Tap a mailbox or folder in the iCloud section."

You can find these steps in Set up iCloud Mail on all your devices - Apple Support.

Regards.
