How to track if your emails have been opened?
Open rate tracking lets you see if your subscribers have opened your emails from their inbox. This metric is influenced mostly by the attractiveness of your subject line.
How to track your open rate?
After enabling the tracker and sending a mail merge, you can see in your spreadsheet that the status changed from EMAIL_SENT to EMAIL_OPENED for each email opened (under the Merge status column).
A tooltip in the merge status cell also indicates when the email was opened.
If you close your Google Sheet, you can open the Tracking Report again by going to Extensions > Yet Another Mail Merge > Open tracking report.

How does YAMM track an opened email?
YAMM embeds a tiny, invisible tracking image (a single-pixel gif, sometimes called a web beacon) within the content of each message.

If you notice odd stats (like a too high/low open rate), read the following articles to understand why: 'My open rate seems unusually low or non-existent' & 'My open rate seems unusually high'.
