I agree - that type of message just tells me that I don't want to partner with you. But it is a form of cold calling...
It sure is, something that we block completely. There is good and bad cold calling, though. If you cold call me and ask to speak to me, I'm not going to be pissed, I'll just hang up. But if you cold call and demand to set something up rather than politely asking if we can.... we are done and you are actively blocked and will never get our business.
There is legitimate sales and downright unprofessional "never do business with them" sales. A company doing these tactics definitely does not believe in their own product and is trying to get sales through an intimidation style rather than through presenting a good product.
