Does the "Opens" count go up if an agent opens my email more than once?
No. Each email is only counted as opened once, no matter how many times the agent or manager opens it.
If an agent opens your email today and opens it again another day, your "Opens" count stays the same — it will not go from 1 to 2. What does change is the open date: the Tracking Report updates to show the most recent time the email was opened.
So if you notice the open date on an email has changed, that's a sign the agent has come back to your email — even though the count hasn't moved.
Keep in mind that open tracking works by loading a small tracking image, so it's a helpful indicator of engagement rather than a perfect measurement. Some email clients block images (an email may be read without registering an open), while others preload them automatically.
