- Poor grammar and/or spelling
- Poor language structure
- Lack of proper identification
- Names cannot be searched in Google or Yahoo!
- Request for immediate reply
- Request for personal information
What do I mean by poor language structure? Well, in case the grammar seems fine and the spelling checks out, look for words that don't make sense together. For example, a lot of spam emails I've received end with something like, "I am look forward to reading from you." Yeah, right. And I am seek writing to you write now.
If the email has any identification at all, it's usually incomplete. This sign goes hand-in-hand with a lack of verifiable search results from Google or Yahoo. The sender's email address, the sender's name, any company or organization name, etc, with or without quotes in a search bar, will probably yield either vague or no results. Try looking up the name John Smith, for example. Good luck. Which one is it? Sometimes, there is a legitimate sounding company, like Good Nature Charity. See if you can spot them in a sea of over 1.5 million search results.
Emotions are a huge motivating force. Both spammers and used car salespeople know this. That's why the response needs to be quick. But take time to do a little research and trust your skepticism. If it has a strong emotional appeal, or sounds too good to be true, it's probably not good for you. One spammer made the mistake of specifying that a well-known government agency, with a specific name, was a supporter. Well, I searched for the referral's website and contacted them. I knew the answer before it came: they never heard of them, would never endorse something like that, and advised to stay clear of them.
Lastly, anytime there is a request for personal information it should raise a red flag. Personal information, such as birth date, social security number, driver's license, bank account, credit card, passwords, etc, should never be sent over email. Yes, I know we send passwords via email (as reminders to friends or business associates), and we get them when we click 'Forgot Password' on a site we use. But, the key is that we're familiar with them. Never send any of these things to a stranger.
I hope that helps. I plan to provide some real-life examples, even though I've deleted most of my spam. (There's always more. Sigh!) Also, I'll provide some insight into why some email goes to the junk folder. It's not always obvious, like a certain word used in the subject line. (That's why a lot of spammers intentionally spell these words wrong; so they won't get caught by the filters.) I'll also walk through a scheme-scenario that seems very real, but could cost you money and major hassles, let alone embarrassment if you fall for it.
