I have an email list of 4,000 people from signups to our vBulletin forums. I tried experimenting with a way to track who opens the email. I wrote a php script to log who opened it before serving an image.
<img src="host.com/script.php?username=test">
It seemed to work at first, as there were people being logged. I understand the obvious drawbacks to this, such as spam filtering, and email clients blocking images. Only its been a couple days now and I've only logged about 250 people. That doesn't seem right, out of 4,000?
