@Acer Honestly I wouldnt even bother to apologize, I doubt most people would be offended. You could remark on it briefly if you have a follow up email for some reason. But I wouldn't really go through the trouble of apologizing in its own email for just that.
If you do feel the need to correct yourself and apologize I would keep it very brief and just reply with something like "I noticed after sending the last email I misspelled your name. My apologies"
@Acer Always happy to help.
Americans tend to not be quite as focused on etiquette as asian cultures tend to be. Stuff like that isnt really going to be a big deal thankfully. Generally if people get the sense that you are trying to be considerate thats all that matters.
@freemo
Thanks. It's very helpful.
I am relieved
