Can I use off-the-record style encryption for my emails?

I'm new to the security world but I know that instant messaging uses "off-the-record" encryption (which means that a user would get authentication, encryption and forward deniability).

But for my email, all we use is GPG/PGP, which offers authentication and encryption but doesn't allow forward deniability (which could compromise all of my messages). Now, I'm trying to figure out if "off-the-record" style encryption would be possible for my emails. If it doesn't, what would be a good alternative?

    Possible? Probably, but I'm not aware of any useful technology being available for e-mail at the moment. OTR works in the interactive sessions between IM participants. It's not so helpful in disconnected sessions since decryption keys cannot be allowed to survive for later use by a recipient nor is there a good way to exchange such keys. The exchanges themselves and the necessary intermediate storage makes OTR impractical for now.

    If it doesn't, what would be a good alternative?

    For what specific purpose? And for secrecy against whom?
