Gmail Message URL is the Chrome extension to quickly reach a specific message in Gmail: it generates a unique URL that can be easily bookmarked or pasted anywhere, so you can open the conversation in the future with just one click.
The extension adds a button in the browser and a “Copy message URL” option to the Gmail interface that allows you to copy the unique URL of the selected thread. Gmail message URL is more reliable than copying the URL from the browser’s address bar, as the URL may change when you are signed in with multiple Gmail accounts.
The link works for all people included in the thread, including recipients in CC.
No data is collected or shared because it relies entirely on standard Gmail features.
