I think it's okay... I got one of their regular newsletters later last night, and the links are set up the same way. Kneejerk reaction, I guess, based on the TONS of junk mail I get (like requests to update my bank account, through banks that I don't even know of)
and this one didn't have any of the normal Feld markings or graphics. The thing that really threw me was having a link spelled out with the surveymonkey.com/blahblahblah full address, but when you put your mouse over it, it pointed to some link.p0.com... Somebody on DRR looked it up, and p0.com is registered to Feld. Must be used for tracking, but I really don't like it when a link isn't what it says it is. I'm pretty trigger-happy on the delete button.
