Getting off newsletters

Analysts are information junkies, among other things (I've recently been branded an air-miles junkie, because I live in airplanes). That's why I typically tell a vendor's AR, PR, or marketing department to put me on a distribution list for the company or analyst newsletter, so I stay informed about what's happening with new sales, new hires, new products, alliances, awards, patents, etc. The condition is, of course, that I do actually cover that vendor.

The major players in any one market interact with analysts regularly anyway. However, the smaller vendors often rely on one-way communication through pumping out newsletter emails through their respective PR agency. This is fine as long is I'm able to unsubscribe from the newsletter, which could happen if there were just too many emails coming, the coverage changes, or I just want to reduce the daily infoclutter hitting my inbox every day. One convenient way I noticed for getting off a distribution list is via Roving's SafeUnsubscribe feature. One click, and you're off the list. When I saw that this has been already available for a few years, I was wondering why those email centrifuges in the PR community are not considering that option, as it would most certainly make a much more professional impression. Then again, does the centrifuge care where the stuff that's flying off really lands?
