For me the issue isn’t spam filtering, we test that before we send out our client’s campaigns. What the real problem is that lack of feedback in the form of open rates because the technique used is to have an image retrieval request signify and open. This forces us to use trending as the means to show improvements to open rates, but that is for a completely different discussion.
