How do I change my Apple Account to a new email address?

Re: "Want to remove old email

I was trying to update my cookie jam game. But it tells me to login with my old email. How do I remove it"

If this is the email address that you use for the app store, that you want to change:

See: Change your Apple Account primary email address - Apple Support

Eg: says:

Change your Apple Account primary email address on your iPhone or iPad

1. Go to Settings, then tap [your name].
2. Tap Sign-In & Security.
3. Tap your primary email address to make changes.
4. To remove this email address from your account, tap Remove from Account. If you want to keep the current email address associated with your Apple Account but change to a different primary email address, turn off Primary Email.
5. You’re prompted to choose another primary email address. You can either choose one of your

other email addresses associated with your account as the new primary, or add a new primary email address.

Follow the onscreen steps to enter and verify your new primary email address.

Learn what to do if you didn’t get the email.
