Spoofing tends to require the recipient to look very closely at the email heading and language for anything that seems a bit off. So if one were to get an email from what appears to be their bank, it would adopt the logo of your bank, the spelling, and even the tone of their messages, but something would be off, like an extra number in the email domain (@1bankofamerica.com, for instance), a request in the subject line or email that the bank wouldn't normally make, and associated links which go to similar-looking websites.

It's all an attempt to convince the recipient to divulge sensitive information, be a victim of identity theft, and/or click on a malware-laden link, amongst other criminal cyberattack possibilities. What helps enable spoofing is that the email transmission protocol Simple Mail Transfer Protocol (SMTP), can't necessarily authenticate the email address, and the information in the fields the recipient sees doesn't have to match the info in the servers used to send the email.

To protect yourself, be wary of any out of the ordinary emails asking for any urgent action involving personal information, and use anti-spam software that requires authentication for incoming emails. Some email programs allow you to inspect the email header, like Gmail, which allows you to click "Show Original," where you can see if the sender domain is different than what it says under "Received." Meanwhile, for those emails seemingly sent from yourself, that you clearly didn't send yourself, users can adopt a Domain Name System (DNS) with various methods of authentication.

The above methods won't stop all the spoofing attempts, but they will certainly making checking your email a little less exhausting, and let you focus on the emails you've been avoiding for different reasons.
