Mail message URL

About

The problem: Gmail URLs in your address bar point to conversations, not individual messages. They can change, break, or lead to the wrong email. If you save or
  share a Gmail link, there's no guarantee it will still work later.

  The solution: Mail message URL generates a permanent link to a specific email message based on its unique Message-ID. This link will always open that exact
  message, no matter how your inbox changes.

  Perfect for:
  • Saving a reference to an important email in your notes, tasks, or documents
  • Sharing a link to a specific message with colleagues who have access to it
  • Bookmarking emails you need to revisit regularly
  • Linking emails in project management tools, wikis, or CRMs

  How to use:
  1. Open any email in Gmail
  2. Copy the message URL using one of three methods:
     - The "Copy message URL" item in the message menu (⋮)
     - Right-click → "Copy Gmail message URL"
     - Click the extension icon in the toolbar
  3. A confirmation appears — the permanent URL is now in your clipboard

  The generated URL uses Gmail's built-in search by RFC822 Message-ID, so it works reliably and doesn't depend on thread IDs or other temporary references.
