When applying for a job through email, skip the cover letter attachment. Instead, include a cover letter email that compels the hiring manager to contact you, recommends "Business Week." An email cover letter should be professional, discuss where you heard about the job and convince the manager that you’re the best fit for the job.
Use a professional email account. Before sending an email about a job opening, pay attention to the details. For example, if your email is unprofessional, open a new account for professional purposes.
Refer to the person by name. An email is similar to a cover letter. You shouldn’t address it “To Whom it May Concern.” If you don’t know the hiring manager’s name, call the organization and find out. This will make your email stand out from the competition.
Mention where you heard about the job posting. The first paragraph of your email should address where you heard about the job opening. For example, you might mention that you heard about the opening through a person who works for the company or through a job posting on Craigslist.
Share a little about your background. According to "Business Week," a good cover letter email should discuss a little about your background and relate it back to the position. For example, an applicant might discuss how their experience in marketing communications gave them experience in research techniques such as focus groups and surveys.
Create a call to action. The call to action is the last paragraph of your email. It should compel the hiring manager to call you for an interview. Mention why you’re a great fit for the position and ask for an opportunity to talk about the employer’s needs further. Also reference any attachments (such as a resume or professional work samples).
In addition to an email, send a hard copy cover letter and resume to the hiring manager. This will increase the amount of times your name is in front of the manager.
Don’t get long winded. An email cover letter should be short and to the point. If your cover letter is longer then 4 or 5 paragraphs, it’s time to shorten it up a bit.
