A Absolutely. Whether you are applying to an advertised role, or you are sending a prospecting letter enquiring about opportunities in a company, a cover letter is essential.

Your cover letter is often the first piece of correspondence a prospective employer will read from you. It can make the difference between your CV being read or being left aside.Address your letter a person not the HR or Sales Manager. When applying for a particular job, state the job title and job reference number if applicable. If you are 'cold calling' state what kind of opportunities you are looking for.

Be reasonably brief - your CV will cover details, dates and facts. Avoid giving an indepth personal profile.

Employers are most interested in what you have to offer. Give three or four key skills or achievements and outline how you will make a contribution to the company in the particular role.

Give reasons why you want to work for the company.

Prospective employers want more than a standard 'mail shot' style letter.

State your availability for interview. Give them your contact details . . . mobile phone number and email. Tell them you look forward to discussing your CV with them in greater detail.

Give your letter to someone with a keen eye for detail to pick up any typos. You should now have a letter strong enough to get your CV considered with interest
