Is it possible to receive encrypted notifications from Wordpress?

I need it to protect user's privacy and data.

Originally I wanted receive to implement end-to-end encrypted notification from my Wordpress when someone submits an inquiry from Gravityform.

My Gravityform database is encrypted with this plugin.

I already tried "WP PGP Encrypted Emails" plugin, but it didn't work very well with my environment.

For the moment, my Wordpress site sends me decrypted email notifications on each submission. I'm not sure this is the best practice 😥

I'm not a tech person, so that was all what I could do so far. I'd like to know if there's a better solution for this.
