Activating click-tracking is very easy with YAMM. The results will appear directly in your Google Sheet (marked as EMAIL_CLICKED) and in your Tracking Report.
As a reminder, you have to enable the tracking feature right before sending your emails.
After sending your mail merge, the tracking report opens at the right of your screen.
If you close the Tracking Report sidebar, you can open it again by opening YAMM, and clicking Open tracking report.
The mention EMAIL_OPENED turns into EMAIL_CLICKED on the Merge status column of your spreadsheet when your link is clicked.
