This is the reason I use Mailwasher (if you're downloading your emails to your computer as I do).
Mailwasher allows previews of spam and unwanted emails, allows you to mark senders as spammers - and best of all, allows you to bounce spam and scam emails, so it appears your email address is invalid.
The number of spam and scam emails I now receive would total about 2 a week at most on average - out of around 70-80 emails a day.
I quite often go for 3 weeks without receiving a single one.
Be aware that databases of email addresses are regularly sold, both legally and illegally, to anyone who wants to buy them.
