Hi gelon32,
It seems you got mixed up in having two different email addresses in use with your devices and services.
Subscriptions through Apple are linked to your Apple ID account.
Subscriptions, content, apps and other services can’t be transferred between accounts.
For this reason, users are encouraged to use one single Apple ID account for all their devices and services.
Your Apple ID email acts as the name of the account. You can change it to a different (and unused through Apple) email address. Change your Apple ID - Apple Support
If you meant something else, then please elaborate.
