remember how it feels receive unsoliciated mail. Especially one that has nothing to due with business and having to take someone off their usual job to rid of 1000 cranes or the likes.
Like if I have 1000s of items, and randomly shipped them off to people. I suspect some may not mind, other will find it highly annoying, and some probably would want to bash my head in. Which majority of them going straight to the trash can.
At our office, we make a list. Unsolicited first timers go into a database and send out on message, organizational wide, to ignore and or do not entertain the sender. And usually the package is returned to sender or immediately destroyed. If they continue contact, usually they are sent a notice about harassing federal government office and if they continue such and such can happen. And I seen cases published in the Army Times I nthe past where they actually followed through civilian and soldier alike. Straight federal offense. Now of course most corporations don't have that type of clout but may find it just as annoying to receive extra unsolicited items, which they probably have enough to deal with in the first place, without notice asking, or even a warning. Now if it's sending 1000 cranes at one time, it could be considered spam too. Aka unwanted unsolicited mail, usually in electronic form but currently used to also pertain to physical unwanted mail too.
Seriously, we already sent them a blind pitch or semi-blind pitch in Google case, lets not pester them with more junk stuff and basically adding to their workload with the nonsense they must deal with day to day.
Call them up and ask them if they want a bunch of paper cranes or a bunch of other items.
