If you value privacy, you've come to the right place. Like ProtonMail, we believe in end-to-end and zero-knowledge encryption. But we also believe in your freedom. PDG Mail is built on a foundation of open standards—including full IMAP, JMAP, and SMTP support—giving you the power to use any email client you choose without being locked into a proprietary ecosystem. Get world-class privacy, powerful search, and complete control over your data, all protected by Hong Kong's privacy laws.
Privacy Without Compromise
Some encrypted email providers force you to sacrifice features for security. For example, end-to-end encryption can limit search capabilities and prevent you from using standard email clients. At PDG Mail, our architecture is designed to provide zero-knowledge privacy and a first-class user experience. We give you full-text search of your entire encrypted mailbox and the freedom to use clients like Apple Mail or Thunderbird, so you don't have to choose between privacy and functionality.
Moving Made Easy
Because ProtonMail restricts data export, moving requires using their official export tool. Our step-by-step guide walks you through using the tool to export your data and import it seamlessly into PDG Mail, ensuring your encrypted emails remain secure throughout the process.
- Export from ProtonMail: Use the ProtonMail Export Tool (available for Windows, macOS, and Linux) to export your emails. You will need a paid ProtonMail plan to do this. Export your emails in MBOX format.
- Export Contacts & Calendar: Export your contacts as vCard files and your calendar as an ICS (iCal) file from the ProtonMail web app.
- Sign up for PDG Mail: Get your new PDG Mail account.
- Import to PDG Mail: In the PDG Mail web app, navigate to Settings → Import. Use our MBOX import tool to upload your email archives. Then, import your contact (vCard) and calendar (ICS) files through the dedicated sections in our web app.
Once imported, all your data will be encrypted with your key and fully searchable within your new PDG Mail account.
Frequently Asked Questions
Why do open standards like IMAP and JMAP matter?
Open standards ensure that you are never locked into a single provider or app. Full IMAP and JMAP support means you can access your PDG Mail account on any standard email client, on any device. This guarantees data portability and gives you the freedom to choose the tools that work best for you, rather than being restricted to a provider's proprietary applications. It's your data, and you should be able to access it however you want.
How can you offer full-text search if my emails are encrypted?
Our system creates and stores an encrypted index of your emails. When you search, the query is sent to the server, which searches the encrypted index and returns encrypted results to your client. Your client then decrypts the results for you to view. This allows for powerful, fast search functionality without ever exposing your unencrypted data on our servers, giving you the best of both worlds.
How does PDG Mail handle end-to-end encryption with external users?
We believe in giving users control. You can use any PGP-compatible client (like Mailvelope for web or Canary Mail for desktop/mobile) to manage your own keys for end-to-end encrypted communication with anyone, regardless of their email provider. Our zero-knowledge system ensures that all mail stored on our servers is encrypted at rest, and only you hold the key.
