Gary Thuerk was the first person to send email spam message in 1978 to 600 people. He was warned and told not to do it again. Currently, sending spam email is banned by the Terms of Service/Accepatable Use Policy (ToS/AUP) of the internet service providers (ISPs).
However, this kind of ban does not stop the incoming of unwanted emails. This happens because while visiting some websites, you need to enter your email id to get the information from that website. This entering of email automatically makes you give permission to the website to send “updates”.
