Euromail: “North America and Europe are two continents divided by a common technology: e-mail. Techno-optimists assure us that e-mail—along with the Internet and satellite TV—make the world smaller. That may be true in a technical sense. I can send a message from my home in Miami to a German friend in Berlin and it will arrive almost instantly. But somewhere over the Atlantic, the messages get garbled. In fact, two distinct forms of e-mail have emerged: Euromail and Amerimail.”
I have the same experience. After working for a few years in the US (and the UK), I am acculturated to their “loose” email use. When I’m emailing with European business partners, I always have to adjust my tone and formalism – because that’s what they do.
