• Has anyone tried to encrypt the submitted form with PGP/ GPG? So the E-Mail with its content is end-to-end encrypted?

    I think this is important if users send sensitive data. SSL alone is not enough in case someone gains access to your server. I already make use of the option to not store the submissions in the WordPress database.

    Maybe something like Simplesecure ? (Gravity Forms seems to have a plugin for PGP encryption. See “wp2pgpmail”)
