12 Common Errors to Avoid

1. Addressing the letter "To Whom it May Concern."
Whenever possible address the letter to a specific person. Call the company to find out who will receive the letter and address it to them. If you have done your research, but still do not know who to address the letter to, ensure that you greeting is not gender biased.  For example, do not address letters using "Dear Sir."  Use greetings such as "Dear Hiring Manager," "Dear Human Resources Manager," or "Dear (company name) Representative."

2. Using a form letter or mass-mailing the same letter.
Each letter should be written by you and customized to the particular company and position for which you are applying.

3. Wasting space.
The cover letter is only one page long so you must be succinct. Only include those aspects of your credentials and background that are relevant to the company and position that you are applying for.

4. Focusing on "I" rather than "you." 
Make sure that your letter emphasizes the company rather than yourself.  Use the word "I" sparingly and try not to begin sentences with this word.

5. Including erroneous company information.
Make sure that you confirm any information that you include from your research and never bluff or guess about company information.
6. Confessing your shortcomings or misrepresenting yourself.  
Although you should leave out confessions (for example about lack of experience), you should never misrepresent yourself or exaggerate your credentials.  Instead, focus on your strengths and what you can bring to the company and position.

7. Handwriting the cover letter or making corrections directly on it.
Type or word process your cover letter. If you detect an error, correct it on your computer and print it out again.  Handwritten letters or corrections show a lack of effort and professionalism.

8. Missing signatures or enclosures.
By forgetting to sign the letter or include documents that are refereed to in your letter (your résumé, transcripts, etc.) you are indicating that you are careless
.
9. Grammatical, spelling, or typographical errors. 
Using a spell (or grammar) check feature from your word processor is helpful but it may not catch all the errors. Proofread it yourself, then have a friend check for errors as well.

10. Using slang expressions or clichés.
Never say things like "I am a people-person", or "I am a top-gun in my class". Keep the letter professional.

11. Using abbreviations.
Take the time and space to write out the words rather than using abbreviations.

12. Including photos or personal information.
Unless it directly relates to the position for which you are applying, it is best to leave out anything which might provide a basis for unlawful discrimination.
