Each email address can only be linked to one Fatsoma account, so if you're seeing a message saying your email is already in use, it means there's already an account registered to that address.
Rather than creating a new account, try logging into your existing one at fatsoma.com. If you can't remember your password, you can reset it by visiting fatsoma.com/forgot-password and following the steps from there.
Once you're back into your account, it's worth knowing that you can update the email address linked to your account at any time in your account settings at fatsoma.com/settings. This is handy if you'd prefer to use a different email address going forward.
If you're still having trouble accessing your account after resetting your password, please get in touch with our support team and we'll help you get back in.
