It seems like a ridiculous question.
I didn’t know it was Spam.
It looked legitimate.
I thought it was from my aunt Gertrude.
I needed to lose weight and it looked promising.
The endless list goes on and on, but the truth is marketing. You were a recipient of well planned marketing. No matter what you think the reason you responded to the Spam was the reality is you were “hooked”!
The subject line or that is was from someone who looked familiar, whatever it was you took hold of the line. That is what marketing does. Good. Bad. Legal. Illegal. All the same, it hooks you.
Would you open the front door of your house to someone who maybe looked like someone you know? NO!
If you start looking at your email as a real life communication channel, like your front door, you would think twice and stay away from the curiosity that is often just bait for bigger troubles!
