I’m not sure if I’ve misinterpreted your post, If seems that you’re not really concerned with your Hero Bitcointalk account, but rather with your email account (and derivates it could facilitate access to). If that were so, the OPs title would be somewhat misleading, as the Hero account is secondary to the narrative.

Regarding email recovery, there’s not much that can be said other than what your email provider will have described in the recovery procedures. Failing that, there doesn’t seem to be that much else to do to regain control, although it will depend on factors that have not been specified (i.e. specific email provider, possible linked email accounts and or phones for recovery purposes, and so forth).

As to the Hero account, the recovery procedure has been linked in the posts above, were you to eventually become interested in regaining control.
