Thats about typical for breadcrumbs. In this situation, the breadcrumbs must have been coded to follow your history or cookies during your browsing session. I cannot really know unless I view the coding myself.
I must also ask how much security do you have set on your history/cookies options in your browser, and what browser are you using?
Also, just because the breadcrumbs doesnt pop up on a specific email link to the site, does not mean they are not working properly. Breadcrumbs are there to let you know where you came from to where you are. If you came from your email program, then these particular breadcrumbs may be coded to ignore the trail.
