Writing Emails in French ?

I receive many emails each day. No doubt, they are 99% French ones. Unlike at the beginning, I now understand French emails (at least I can guess the meaning :) ). In the worst case, I use online translation services. 

These days, I write emails in French too. I remember the hardest day when I tried to write email in French to get my transcript from Telecom SudParis. It was little bit urgent. As the lady there doesn't understand English, I must write it in French to get quickly processed. So terrible time ... I still remember. I laughed a lot when I knew transcript in English is "relevés de notes" in French :))...coz I was thinking a single word in French corresponding to that English one. I had  so much funs :)) and pains too :((. Now such practice is making my life easier...

Below I'll present the most commonly used French phrases in French emails so that I can reuse or anyone who wants to write email in French can use them. Note that the bold words are in English.
-----------------------------------------------------
Normally we start writing email with a greeting 'Bonjour' (Hello) in the email. 


Hello
Bonjour,

Hello Nobal,
Bonjour Nobal,


To write a very formal greeting like Dear in English we use Cher. I found such greeting in emails from organizations like Bank :)).

Dear Customer (male),
Cher Client,

Dear Customer (female),

Chère cliente,

-----------------------------------------------------

Sincerely,
Nobal

Best Regards,
Nobal
Cordialement,
