Hey! Great question, and this is a common situation.

The "email already taken" error means your professional email is already registered as a separate account in Decile Hub. Here are your options:

1. Delete the existing account linked to your professional email, so you can then update your current profile to use it. Our support team can help with this.
2. Invite that email as a teammate/admin on your current account and switch to logging in with it instead.

Since you likely haven't used the other account much, option 1 is usually the simplest path. To get this sorted, please reach out through the contact page at decilegroup.com so the team can verify your identity and make the change securely.

Let us know if you have any other questions!
