I work in an office, send loads of emails and have conversations that can be ongoing for maybe 10 emails with the same person.
Now when i get an email say John, i would always reply " Morning/afternoon/Hi John" in my first initial email but then after that i will just reply as normal.
Ive noticed that most people when emailing replies and with every reply will always start with "Hi smashinghope"
Im now concerned i look blunt just going straight into my subsequent replies but it feels very unatural to keep saying "Hi John" every 3 mins when replying.
Does this even make sense and whats the correct etiquette?
