I believe this is true, because addressing the reader's name is sort of informal and not suitable in a cover letter.
Compare and contrast would be your answer.
Samuel Langhorne Clemens (Mark Twain) uses a fine humor style which is easily detected in extracts like:
<em>"Thish-yer Smiley had a mare; the boys called the fifteen minute nag(...) for all she was so slow and always had the asthma, or the distemper or the consumption, or something of that kind."</em>
<em>"...And he had a little small bull pup, that to look at him you´d think he warn´t worth a cent(...) his underjaw´d begin to stick out like the fo´castle of a steamboat..."</em>
<em>"...He ketched a frog one day, and took him home, and said he cal´klated to edercate him(...) and you bet you he did learn him, too.</em>
Twain is satirizing several aspects of American life, but specially the country "punks" who tend to speak at length about subjects that are close to them but are really unimportant an nonsensical.
Try using better words for the little words you use. Maybe for an example say, And this is the reason because. Or maybe another reason due to this is...
