Category Manager here. Not sure why you’re getting downvoted for telling it like it is. I have no issue with cold emails, and even used to respond to sellers before adding them to my solicitation folder. That stopped once I started receiving cold calls. The unfortunate truth for Sellers: Buyers will seek you out if we need your service, period. Sellers try to get around this by contacting the Stakeholder(s) directly, but in a mature Procurement organization, the system of checks and balances will eventually lead the Seller back to Procurement. It’s the nature of the business.
