We've been busy. Here's what's new across the Postern product line.
New — Postern PGP Mailer for WHMCS
Your WHMCS sends invoices, password resets and support replies in plain text. Postern PGP Mailer is a drop-in WHMCS add-on that automatically PGP-encrypts outbound email to any recipient with a published key — and sends normally to everyone else. No workflow changes, no per-message effort.
- Automatic PGP/MIME encryption — body and attachments
- Opportunistic key discovery via keys.openpgp.org and WKD
- Covers WHMCS templates and custom emails
- Runs on your own SMTP — nothing routes through us
- One-off £50, per installation

Postern — your mail, on your hardware
Postern is a privacy-first, self-hosted email client: pull your mail off the provider into an encrypted SQLCipher vault on hardware you control, with built-in OpenPGP and Autocrypt so encryption just works between you and anyone Autocrypt-aware.
- Community — free and open source, up to 3 mailboxes.
- Pro — unlimited mailboxes, mesh access, opt-in local-first AI, calendars & contacts, and one-click updates. One-off £100 with 3 years of updates.
