well then that's truly sad, I've got an issue with suddenly no receiving emails - contacted provider, contacted support here, I got same advice:
"Sign a message from the Bitcoin address in the profile or an address you previously deposited from requesting the email change."

So there is truly NO FURTHER OPTIONS right?

The problem I described is if you haven't changed the default withdrawal address in your profile.

Otherwise, you can follow the second option in their instruction which is any address you've used to deposit bitcoins to your account.
But I can't quite figure out "or an address you previously deposited from" but it seems like the address you've used in your previous deposits, there's no other addresses a user can sign anyways.

Anyways, if you've deposited before and can't recall the address used, you can open their deposit page:
"Profile->Deposit" and there's a list of "old deposit addresses" below that window.
You can paste them to a blockexplorer to check for a transaction that looks like your previous deposit and take note on the input(s).
If it belongs to the wallet you used to deposit and it's non-custodial, you can try to sign a message using that address.
