In an informal letter, is writing just Bonjour! or Salut! without a name acceptable?

Answer 1

I don't see why it wouldn't be acceptable. It's an informal letter, not a business letter.

if it was a formal letter you would say, " Bonjour Madame *insert name here*!

But with an informal letter, it should be okay to exclude a name.

Answer 2

Thanks!

Do I close the letter in the same manner as English?

Ex.

Amicalement,

*My name*

Answer 3

Yes, always.

& no problem. :)
