If Apple tries sending you a verification email and you do not receive it, read this support article --> If you didn’t receive your verification or reset email - Apple Support

"When you make certain updates to your Apple ID, we’ll send you an email to help you complete the update. For example, you might have reset your password, reset your security questions, or added a new email address to your account."

I don’t think you can change the account’s email address. Instead, just add another email account, like “<name.here>@icloud.com.

Last I checked the accounts are free.

Then, you might forward all messages from the old account to the new one. But - if you don’t want to get email there at all, go to your mail accounts on your iPhone and “sign out” from your old iCloud account.

I don’t know if you can delete the old iCloud email account completely.
