I hate getting cold calls. So I avoid doing it to other people. Yes that makes me less of a salesman. So be it. Tangent: In India you can report unsolicited sales calls to a central (government) authority, where you can sign up to get on a "Do Not Disturb" list, and get any sales caller who ignores this fined, and eventually get his number disconnected etc. The system isn't perfect, and there are some impressive hack…
I occasionally receive emails from lists specific to trendy-looking SaaS/PaaS products that I've never even heard of. Just the same the emails will start rolling in telling me that my wait was up and their launch is just beginning and "come grab a promo-price for one month" if I sign on for a year, etc.
When I first received anything like that, I thought maybe I'd just forgotten that I'd seen it and asked for updates— but no. After seeing more upon more, I realized that I was just getting spammed. Except none of it gets filtered out, because they don't carry the markings of what I'll lazily classify as 'traditional' spam.
