User reviews

Users appreciate Mailvelope for making PGP encryption easy and accessible on webmail platforms like Gmail, offering strong privacy and straightforward use. It supports integration with existing keyrings and multiple browsers. However, there are notable issues including compatibility problems with Chrome's Manifest v3, initial key recognition troubles on Windows, and limited advanced features. Some users find installation and usage somewhat cumbersome, and Google's security mechanisms limit use under its Advanced Protection Program. Overall, Mailvelope is well-regarded but has challenges affecting reliability and user convenience.
Pros
  • Makes PGP encryption accessible and easy to use for webmail, especially Gmail.
  • Provides high-level security and privacy by enabling end-to-end encryption.
  • Minimalist and straightforward interface; 'just works' out of the box.
  • Supports integration with existing GnuPG keyrings and is open source.
  • Compatible with various browsers and some webmail clients beyond Gmail.
Cons
  • Issues with compatibility after Chrome's Manifest v3 update, potentially breaking functionality.
  • Problems on Windows with recognizing GnuPG keys on first use, requiring workaround steps.
  • Limited support for advanced features like HTML content or using applications like mailtrack.
  • Not officially approved for use with Google's Advanced Protection Program, restricting some users.
  • Installation and setup can be cumbersome or confusing for some users.
