Track if sent email has been opened
Posted on 2013-01-11
I'm trying to figure out a way to track if a sent email has been opened.
This could done with a tracking pixel, but i don't know how it works.
The emails that are sent are customized emails that load external images from a remote server.
What would be a good way to do this? I believe some kind of fairly easy trick to accomplish this exists, so i don't want to use any external software, i'd rather build it myself.
