I have numerous email addresses that take a decent amount of time to manage, due to spam and such.
So, I consider a cost of time, potentially over many years, before giving out my email address.
Some sites will offer something free, yet take your time, attention, and information, before getting to the free part.
This site isn't bad, in that they only ask for your email address.
However, strictly speaking, I'll still say it is not free.
