Wish someone luck at the beginning of a letter?

[WZ]

Hi.
I was wondering if native English speakers ever begin a letter by wishing someone luck/health or something like that?
E.g. Can I begin a letter with "First of all, I'd like to send my greetings (is "greeting" OK here?) to your family"?

Yes, that's OK. You can also use expressions such as "hope you are well".
