Murena’s SnappyMail integration with the Mailvelope extension allows you to encrypt/decrypt/sign your emails, as well as create/manage PGP keys right in the browser. This makes it easier to secure your emails end-to-end and protect your privacy.

Step 1: To begin, download and set up the Mailvelope browser extension. You can install Mailvelope on Firefox, Chrome, Edge, or other browsers that allow installing extensions from these sources.

Step 2: Configure Mailvelope

  • Launch the Mailvelope extension.

  • Select Let's start.

  • Import your PGP keys or generate a PGP key if you don’t already have one. If you’re new to PGP keys, check out Mailvelope’s FAQs on Managing my own keys and Sharing and using keys. Setting a password for your key is highly recommended.

  • At this point, you should also import the public keys of your recipients, so you can send encrypted emails to them. You can ask them for their key directly or search for their public key on PGP key servers. Mailvelope makes this easy for you by allowing you to search for keys within the extension itself, under Key Management.

  • For more security, you can choose your operating system’s key management solution. Visit the key management settings in Mailvelope to change that.

Tip: Heads up! Please remember to backup your keys at a safe place, like a pen drive or, if you prefer, Murena cloud.

Step 3: Authorize to integrate with Mailvelope.

  • Navigate to

  • Open the Mailvelope extension.

  • Select ‘+ Authorize this domain’.

  • Enable API access, so you can access Mailvelope functions from Murena cloud.

  • You can manage your Mailvelope settings in Murena’s SnappyMail once you have authorized

Step 4: Choose a distinct security background to avoid phishing attempts from other apps. You can do so by going to Mailvelope’s settings.

  • If you have set a password for your PGP key, you will be prompted to enter it.
