Each cover letter should be about three paragraphs in length. Anything longer risks not being read.
Ideally try to address the cover letter to the specific person you know will be reading it. Otherwise avoid gender references.
Use good keywords in your cover letter just like you do in your resume as later on if a new job opens it may get found in a database search.
Some companies block all emails with attachments for virus protection so be careful about attaching a letter to an email.
Testimonials and excerpt quotes from others about your achievements and performance can add credibility to your cover letter.
