If a sales/business dev guy sent me a unsolicited message promoting their latest ad delivery platform or obscure SAAS solution, with VSRE at the end of his message - I would definitely view his approach in a better light.
Which, despite the "VSRE," would probably still come across as douchey. I don't think the op's idea would actually even work in practice, because the recipient still isn't communicating that what they are saying is polite. For all the sender knows, they could still be saying it gruffly.
But, likely my response would still be: "No."
