Our accountant has been trying to add my email as a user to Campaigns but the "Join Account" link always leads me to the notice that there's a mismatch in the email address. We've double and triple checked but there was no spelling error. We even signed in and out of out accounts but the error still persists.

I now have an account in Campaigns under an organization name I had to key in myself, and I need to be added to my main organization. Deleting my account and sending another invite won't work because of the issue as mentioned above. Is there way to solve this?
