What is Mailvelope?

Mailvelope is an open-source browser extension that brings PGP encryption to webmail such as Gmail, Outlook, WEB.DE and other providers. It lets you encrypt and sign emails and attachments, manage your keys and spot phishing through signature mismatches, without changing your email address. The private-user version is free and available for Chrome, Firefox and Edge. Separate paid Mailvelope Business plans cover Google Workspace and Nextcloud organisations.

Pros: what Mailvelope does well

  • Free for private users
  • Works with the webmail address you already have
  • Open source code

Cons: where it falls short

  • Both sides need PGP keys to read encrypted mail
  • Key management takes some learning

Who Mailvelope is for

People who want end-to-end encrypted email without leaving Gmail or Outlook.

Who can skip it

People who already use an encrypted email provider.
