Frequent Cover Letter Errors

Using pre-printed form letters rather than individually typed letters
One or more spelling, typographical or grammar errors
Using overly formal language, rather than writing as if having a conversation with the reader
Typing on "erasable" paper, or using copy paper instead of "resume" bond paper
Lack of organization, failing to have an attention-getting opening, persuasive middle section and/or a motivating ending
Double-spacing letter so that it takes two pages to cover what could be said in one
Lacking graphic appeal. Typed too high or low on the page, margins too narrow, or using dot-matrix printer
Paragraphs are too long and uninviting to the reader
Forgetting to sign the letter, indicating a lack of attention to detail
Using one or more initials rather than first name, projecting coldness and leaving the reader ignorant as to whether a response should go to "Ms." or "Mr."
