One of the most obvious signs of a scam email is spelling errors. If you want to persuade me to click on your dubious link, starting out with the phrase “Dear Costumer” is not going to do the job.
Let’s be clear: this is a poorly-executed scam anyway. It doesn’t remotely resemble an actual email from Amazon, and it points to a domain that very obviously isn’t Amazon.com. But the “Dear Costumer” opener sets the lack of credibility very early on. Accuracy matters, even when you have nasty intentions.
