Open Source
Being an open-source extension, GPGMail's code can be reviewed and audited by anyone, helping to maintain transparency and trust in its security features.
Integration with Apple Mail
GPGMail integrates seamlessly with Apple Mail on macOS, allowing users to easily encrypt and decrypt emails within their existing mail client.

Complex Setup
Setting up GPGMail can be complicated, particularly for users who are not tech-savvy, as it requires generating encryption keys and configuring them properly.
Compatibility Issues
GPGMail may experience compatibility challenges with some versions of macOS and Apple Mail, particularly after system updates, potentially disrupting users' workflow.
Limited Support
As an open-source project, GPGMail may not offer the same level of customer support as commercial solutions, which can be a drawback for users needing assistance.
Recipient Requirement
Both the sender and recipient need to have the necessary encryption setup and keys, which can limit its practical use if the recipient is not equipped to handle encrypted emails.

Enhanced Privacy
Secure Gmail uses encryption to protect the contents of your emails, ensuring that only intended recipients can read the messages, thus enhancing privacy.
Easy Integration
The extension integrates seamlessly with Gmail, making it easy to use without requiring significant changes to how users interact with their email.
Free to Use
Secure Gmail is available for free, providing an accessible security solution for budget-conscious individuals and organizations.
User-Friendly Interface
The tool offers a simple and intuitive user interface, which helps users to encrypt emails without needing technical expertise.

Recipient Limitations
Recipients have to know the password to decrypt the messages, which can be a barrier if the password is not transmitted securely.
Limited to Gmail
Secure Gmail is specifically designed for Gmail users, which limits its usefulness for those who use different email services like Outlook or Yahoo.
Not End-to-End
The service does not offer true end-to-end encryption as there might be stages where data is vulnerable if the sender or receiver does not follow best practices.
Potential for Forgotten Passwords
Since decryption relies on a password, there is a risk of losing access to email content if the password is forgotten.
