Email Open Tracking: Bypassing an email forwarder that strips the attributes in an image tag?

203 Views Asked by At

This may be impossible but I figured I'd give it a shot. If the service that I am using strips the attributes of an image tag => , is there any way that I can get around it?

I tried inserting random unicode characters to break the parser but that failed miserably...

My ultimate goal is to be able to track the email opens and the only way I know how to do that is through an image in the html of the email...

Thanks! Jonathan

There are many ways to track opens. Like for instance requesting a CSS-file from server, clicking any link, loading a bgsound, or rendering one specific (or any) image. The transparent pixel ist the most common way.

(As I don't see any option to ask for more details besides answering: What service? And what attributes get stripped?)
