Receiving spam really decreases my quality of life even at work. It also instantly puts you on my shit list and I won't do business with you even if I need the product.

I get a lot of spam from sales people at work (IT architect for a large Enterprise). A lot of them clearly never bothered to read my LinkedIn profile (offering solutions that have nothing to do with my field) but are really pushy, demanding a meeting and keep pinging me long after I've blacklisted them though their first email. Usually even including prearranged zoom meetings. I check my junk box once a month or so for legit emails and it's usually full of followups.

Of course I never respond as it will only cause them to follow up more and to demand names of more colleagues to harass.

If you really want me to be interested in what you have to offer, make sure I find it and hear great things about it when I go looking for something I need. It's a lot harder than just buying a list of emails and spamming but also a lot more ethical.
