Most of the time when I'm composing e-mail in Japanese it's either:
- A friendly, informal e-mail to a friend
- A request for tech support or similar customer service
When composing these e-mails I tend to want to use 拝啓 and 早々, as I was taught for regular letters in class, but they feel far too formal or stilted. I've occasionally used こんにちは as an opening, but due to the nature of e-mail that feels like it may or may not be appropriate depending on the time it is received.
What is the typical practice for phrasing openings and closings in these e-mails?
Note: Saw this when prepping, but it doesn't cover what I was looking for.
