Address the person by name (for example Mr.Tarun or Mrs. Pooja) in the salutation - to give it a personalised touch
Choose a typeface that is clear and easy to read, such as Arial or Courier
Proofread carefully. Check the letter twice over to avoid misspellings and grammatical errors
Digress from the topic. You will lose the reader's interest
Address the letter to a department - it may not reach the right person
Attach a photo - nobody is interested in your looks! In fact, it could disqualify you right away.
