I received a targeted mailer, addressed to a former owner of my house, with an RSVP code for an Amex Business Plat with 100K MR after $10K spend/3 months plus 50K MR after $10K more in the following 3 months (so 150K MR total). I haven't done an Amex business card at all before so shouldn't have a churning problem with this application. I can hit those targets without too much effort.

Question - I know the rsvp code is single use, but can I use it even though it was targeted to someone else?
