Hello James,
Thank you for your question regarding your BoldGrid connect key. You should be able to change the email address if you are requesting the key right from BoldGrid.
If this still does not work, as this is a public forum, I would recommend contacting our Support team directly. You can call, chat, or email them, and they should be able to assist you with specifics about your BoldGrid site.
Gratefully,
Casey B.
