I can’t stress enough, I am not the Alastair Campbell who used to be affiliated with the UK Government, so there is no point in sending hate mail or after dinner speaking requests.
Email wise I’m on ac (at) alastc dott com.
For encrypted email, use PGP with my GPG public key (you’ll need to send me your public key first, then the encrypted email).
