Identifying such emails is something I pound into everyone I know. My kids, grandkids, clients and neighbors. I have also visited several seniors since they seem most gullible/trusting and are often taken advantage of. Looking out for obvious grammar and spelling errors is the first sign I tell them to look for.
I tell them to read the email out loud - the same trick I taught my kids when they were creating school or work papers. When you read it out loud, it forces your brain to not get ahead of itself and autocorrect what it sees. If there is bad grammar, or missing words or the like, it will not "sound" right when read out loud.
That said, I tell them don't bother with any email from their banks, insurance, or credit card companies - even if it reads out loud right. If they get an email, delete it, then call them up on the phone, or visit the bank by entering its regular web address in their browser to access their accounts. If the email was real and/or important, they will be able to see from there what it is about.
