PGP-encrypt your WHMCS email

Automatically PGP-encrypt your WHMCS email. End-to-end OpenPGP for every outbound message — invoices, password resets, support replies — with zero per-message effort.

Postern PGP Mailer Trial License

This is a fully functional 7 day trial license.

Postern PGP Mailer adds true end-to-end OpenPGP
encryption to your WHMCS outbound email. It sits in the mail transport
path and automatically encrypts each message to recipients whose public
key is known or discoverable — invoices, password resets, support
replies and custom emails alike — while everyone else still receives
normal mail. No per-message effort, no workflow changes.
