Hi,
Thank you for reaching out to us!
Unfortunately, it is currently not possible to change the email linked to your subscription.
The only workaround at the moment is to re-create your account with a required email and re-subscribe from there.
Please note, that we wouldn't be able to transfer subscription from your current account over to a new one, nor can we transfer the projects. However, if you decide to proceed with moving to a new account, we can transfer unused minutes over.
If you have any further questions - please let me know!
