US is basically below the EU for wealth with a smaller population. Your response appears to be ignoring the basic facts. So while the US is a big target, targeting the EU on money and population wise would be better, yet they choose to focus on USPS because that converts well.
Since we can assume the US does not have as much disposal cash as the EU since they earn less yet have more wealth. They have less people than the EU. It's that USPS converts specifically well. It looks very likely the reason it's USPS is that folks from the US are very easy to trick.
While I understand it's unpleasing for US citizens to admit that their population is easier to trick. But if they improve their education and stop being so far down in the charts this might not be the case.
What is EU's common language and postal service?
I get a lot of email from European vendors, intended for Europeans who don't know their own email address, and that email is not all in the same language.
