When securing your digital conversations, the choice often comes down to two distinct methods: PGP and SecureSend. These are not interchangeable labels; they are different technologies designed for different communication scenarios. It is important to remember that Canary Mail is a secure cross-platform email client, not a provider, and it works with Gmail, Outlook, iCloud, IMAP, and Exchange to facilitate these security methods.
The Short Answer: PGP (Pretty Good Privacy) is a traditional end-to-end encryption standard that typically fits cases where both the sender and recipient already use encryption keys. SecureSend is a simplified secure-sharing workflow in Canary Mail that allows you to send encrypted, revocable messages to any recipient, even if they have no security setup of their own.

What Is PGP in Email?
PGP has been the "gold standard" for email encryption for decades. It relies on a "Public Key" to encrypt a message and a "Private Key" to decrypt it.
Practically speaking, PGP is an excellent choice for users who communicate frequently with other privacy-conscious professionals, journalists, or security researchers who already have an established encryption workflow. However, it requires both sides to manage digital keys, which can be a barrier when communicating with non-technical recipients. For more technical details, visit our guide on PGP and key management.
What Is SecureSend in Canary Mail?
SecureSend was developed to provide a simpler secure-sharing workflow. Instead of requiring the recipient to manage encryption keys, it sends an encrypted notification containing a secure link. The recipient authenticates via their browser to read the message and access attachments.

This method is ideal for professionals—such as those using a secure email app for iPhone—who need to send sensitive documents to clients or accountants. Because the message is hosted via a secure portal, you retain control: you can see when a message is read and revoke access at any time.
Secure Sharing Workflow
To see how easy it is to protect your outgoing mail without complex keys, watch this demonstration of the SecureSend workflow:
Which Is Better for Mac and iPhone Users?
Apple users often prefer secure-sharing flows that maintain a simple, native experience across devices.
- For One-Off Communication: SecureSend is often preferred by Mac and iPhone users because it works instantly with any recipient, regardless of their device.
- For Established Workflows: PGP remains a strong option when both sides already use an established encryption setup.
- Cross-Platform Authority: While these features are optimized for the Apple ecosystem, this secure workflow is part of Canary Mail’s broader cross-platform model. The same high-security standards apply whether you are on macOS, iPhone, iPad, Windows, or Android.

Feature & Trust Clarity
Before choosing a security method, it is important to understand how these features integrate with your current setup and licensing preferences:
- Works with existing providers: You can use both PGP and SecureSend with Gmail, Outlook, iCloud, Exchange, and IMAP. No provider switch is required.
- Recipient setup differs: PGP requires your recipient to have a PGP-compatible client. SecureSend works with any standard email inbox.
- Trust & Continuity: All security settings are synced via our secure cross-device sync and licensing system.

PGP vs. SecureSend FAQ
Do I need PGP to send a secure email?
No. While PGP is a powerful standard for key-based encryption, SecureSend allows you to send encrypted, private messages without the technical complexity of managing keys.
Can I use these features with my Gmail account?
Yes. Canary Mail is a cross-platform client that adds these security layers to your existing accounts, including Gmail, Outlook, and iCloud.
Is SecureSend as safe as PGP?
The right choice depends on your recipient's readiness and your need for control. PGP is best for established key-based workflows, while SecureSend is better suited for secure delivery to recipients without a PGP setup. SecureSend also offers the added safety of revocation.
Does my recipient need to install Canary Mail to read a SecureSend email?
No. Recipients can read SecureSend messages and download attachments in any standard web browser without installing any software.
How do I manage PGP keys on a Mac?
Canary Mail simplifies the process by allowing you to generate or import keys directly within the app interface. For a step-by-step walkthrough, visit our iPhone and Mac encryption guidance.
