Should I use Chrome Extension or Google Workspace add-on?
If you plan to use Mail Track for Gmail on your desktop, use the Chrome extension: the integration with Gmail provide a seamless user experience.
If you want to send tracked emails from your mobile, use the Google Workspace add-on (directly from the Gmail IOS or Android App).
In the end, these tools are connected, so you can use the two of them!
If any doubt start with the Chrome Extension
The add-on installation seems to be successful but I can't find the shortcut in my Gmail inbox
This issue is affecting all Google Add-ons, it occurs when you have multiple accounts signed in under the same Google Chrome Profile.
An easy workaround is to open a private window, sign in to the Google account you want, and then proceed to the installation.
