There are a few Internet-specific guidelines for cover letters of which you should be aware. First, if an employer has indicated that attachments are acceptable, limit the number of attachments by combining your cover letter and resume into a single file. Use an attention-grabbing subject line, and include complete contact information at the end of your email message.

Even if you have included your cover letter in your resume attachment, you should also cut and paste it into the body of your email message. By including it in both places, you have ensured that the recipient will "meet" you through your email message, encouraging them to open your resume. You have also improved the chances that a scanner will catch words in your cover letter that may not be included in your resume, and that your cover letter will be printed at the same time as your resume. This helps ensure that anyone to whom your resume is passed will also receive a copy of your cover letter. Otherwise, the letter may become detached from the resume.

1. Don't check for typos or misspellings.
2. Send the letter as a separate file attachment without first checking with the employer.
3. Don't include your contact information.
4. Skimp in your cover letter/email, stating only "Here's my application for your available position."
5. Don't include anything on your cover letter that isn't also on your resume.
6. Write a self-centered cover letter, with frequent use of "I," "me," and "my."
7. Include your salary requirements and/or references.
8. Address the letter "to whom it may concern."
9. Create an obvious form letter that's not tailored toward the specific job.
10. Write an amateurish, unprofessional letter.
