We've been sending these for years now, but do they actually do any good?
When I receive them myself, I really don't care about it. Sometimes I even unsubscribe from the sites sending them. So what's everyone's opinion on this?
In addition if the email bounces they may have stopped using that email address, typically if they have moved to a new job. Though I'm not sure what to do about that except try to get them to contact me using other methods.
I really like it when they reply with "Why thank you!" (yes I read the replies)..
