If people bother check sender's email address and domain of the link in the email, they could avoid most scam/spam email.
When it happens, you should create new email address and update email address of services/social media you use.
One of my mistakes when I was a newbie and didn't care too much about my privacy is using my main email to register on different platforms. I even used the same password 
Many of those platforms were hacked and their databases were leaked. My credentials became available publicly all over the Internet! Then, I started receiving similar phishing emails on a daily basis.
