Having been in business for years online, I get hundreds of those emails every week. First, some scamsters can spoof your own email address, or someone else's. Some, lately, don't even bother. You will get email that says they have compromising images, or videos of you (taken with the camera on your computer, even though I don't have a camera), and will, for a price in cryptocurrency, not send it out to all your contacts, or won't alert authorities. There are outfits on the web that put out get-rich-quick schemes to unsuspecting people that sell packages to them with cookie-cutter script, to send out to others with the idea of blackmailing email addresses bought and sold for by these crooks (all with the same bitcoin block-chain number). I get several of the same emails each time I download my email, with only a change in the ransom price, or the email address of the sender. My advice is either change your email address (sometimes hard or impossible), or just delete the email and accept that that is the norm, and you will have to delete or junk the emails from time to time. The newest scam is a tool kit, or some kind of kit you will get from the AAA, or some other entity, or free pillows from the Marriot Hotel chain, if you only will click the link in the email. Mostly, if you hover over the link it is a shortened link, like a bitly link. Another is that your account will be cancelled, or revoked, unless you click on the link. Don't do it!
Most emails I get every day are scam emails. I have other email addresses, which I don't give out, and hardly ever get any email on, much less scams.
Protect yourself, and never be curious. And never unsubscribe to these emails. Then they know it is a live email address, and will turn around and sell it to more scammers!
