This has long been a problem -- when you request Contact Information, the email arrives in HTML code (this is the only eBay-generated email I get that isn't in plain text). I've contacted eBay Support and received basically the same instructions as The Auction Wizard Team posted here. I've always had my eBay email Preferences set for text, and I've reset the Preference a few times, but this hasn't fixed the problem with the Contact Info emails. Telling eBay about this is a waste of time. They just assume you must be misguided in some way.

The contact info is there of course -- you just have to forward the email to yourself and delete all the extraneous stuff before you send it.
