From my experience answering emails from customers all around the world I am not surprised: Spaniards are by far the most difficult to communicate with. It seems even going Google translate way (they write in Spanish and then translate my emails to Spanish) is more difficult with them than with say Koreans or Chinese. I handle emails for the company I've founded for 5 years now. My experience is that nationality of the customer has big predictive value when it comes to how the communication goes. For example: Germans - decent English with funny spelling/grammar quirks (der computer, der solver, using gender pronouns when referring to things etc.) Chinese - rarely write any English but are very smart at using Google translate, I rarely have any communication issues with them. General computer literacy very high. Japanese - exceptionally polite. Often write perfect English. Some of them don't though but they always make an effort (no pasting of Google Translate) and apologize profusely for their English being not so good. Scandinavians: write better English than many native speakers, absolutely no issues. If I were to point the best speaking Scandi country it would be Finland. Russians: often appear rude as I think translating Russian word by word results in rude sounding English. Maybe it's about the culture as well. I like communicating with them though. They sometimes use veiled or not so veiled insults towards me and my software. I keep the tone in my emails sometimes suggesting their brain is just malfunctioning and they are wasting my time. It usually goes well and problems are resolved quickly. French: surprisingly much easier to communicate with than Spaniards. They rarely write correct English but somehow I am usually able to resolve the issue while when I see an email in Spanglish I brace myself for incoming trouble. French email domains (laposte, orange.fr) suck though. They often lose emails without any message. At this point if someone orders using laposte email I am emailing them from my personal account asking to provide functional email address. It sometimes gets to them but not always. We don't have those issues with any other email provider. I could do a few more but those I feel strongest about. I am one guy who sells software to a specific niche. I am also not a native speaker so take it for what it is.
