If you are not technically savvy it’s hard to figure out if an email from paypal or chase is really from who it says it is. If in doubt just make sure that you type the address in yourself. You should be able to remember most of your banking urls, and just open your browser and go there. Don’t follow that lovely link that may save you 1 click or may cost you $10,000. Sometimes its hard for me to spot a fake they are so good, and the biggest issue is if you click the link you may have already exposed yourself.
In the mean time we will keep trying to make the email business a better place so that spammers and phishers can do no harm!
