I am currently writing a cover letter (for a job application) and after a long 'struggle' with the opening paragraph, I've decided to start it by briefly presenting myself and then continuing with
"The reason for which I am writing /to you ???/ is to express my interest in..."
I've already gone through so many other variants that I'm no more able to assess the suitablity/acceptablity of a given phrase, thus I will be very thankful if someone shares their opinion of the above one?
As a supplementary inquiry, I'd also like to ask about the expression "writing to you". I wonder - is it actually neccesary to add "... to you" or that's self-explanatory?
