If Azure, Amazon, Mailgun, Sendgrid etc all monitor their outgoing email traffic, how are people possibly getting around this this to send'SPAM' emails? Note: I understand people use bot-nets, but I'm interested in hearing what other techniques people use.

Important: Let's not hate on the question and assume the questioner has evil intentions :)

I've been through this countless times. I throw together an awesome side project. People tell me they like it. But it dies off. Sometimes I think "maybe this wasn't something they really wanted?", but other times I find competing products doing the exact same thing and think "man, people do want this".

How do you really validate what you've made is something people really want? I guess I would like to know what are methods/hacks of accurately determining this?
