For security reasons, it is not possible to change the registration e-mail. What we recommend is to add the new e-mail as an user of your Account. If so, you can change the account owner to this new e-mail.
Step by step to add user:
1- Go to “Settings”
2- Then go to “Users”
3- Enter the email of the user you want to add to your account and click "Add User"
4- An invitation will be sent to this user's email to create their registration and be part of your account
5- After registering, they will be able to use the account normally with login and password they created
