One of the things that readily annoys me is the "Important Information About your Current Account" letters from a credit card company that are just purchase checks inside. I do tend to open them, just in case; but have never actually used one. I don't think there is necessarily any trickery going on here, but it certainly trains people to ignore mail from them. The mortgage companies are worse, in that they plaster the name of your current (or former) lenders on them; even though they have no actual association. These are usually easy to differentiate from real mail though.
