With the add-in, you can also access extra features (Pro subscription required), that are unavailable on Mailock web, including:


  • Audit - View delivery details, such as when the message was read and how many failed challenge attempts there were. 
  • Revoke - Remove a recipient’s access to a secure email you have sent.  
  • Trigger words - The add-in automatically checks for any sensitive words within the message and prompts if the email needs to be sent securely or unsecurely.
