A way to view the e-mail address associated with my account

I’d to be able to view what e-mail address I had used to make this account. It might have been one from an e-mail provider that recently went down, so I’d like to at least know in advance if I’d be locked out of this account forever once my cookies expire, lol (from what I understand, the only way to log in, at the time of writing, is to click a link that gets sent to the e-mail address associated with the account).
