Try and avoid using a standard letter for each application that you make, not only will it detract from the work you've done to fix up your CV, you will also demonstrate to the reader that you are applying for roles and jobs all together and this could reduce impact.
Instead you can create several paragraphs to re-use in a document then copy and paste them in your cover letter, this will save time but retain that personal touch.
Treat each application as a one off document, you are applying for a specific job and need to promote yourself accordingly.
Your letter should contain: - Bullet point or highlight your skills (in relation to the post applied for) - Explain your reasons for applying - Sell back your skills in relation to the advert - Close your letter with confidence - Use boilerplates In some cases you will be writing to the person that will conduct the initial interview, so a personal letter from you will enhance your chances and will provide a good start for your initial interview.
If you haven't done so already, create a clean home email address that uses your name.
Keep it simple and as corporate as you can.
Also as a word of warning we would not recommend firing your CV off to potential employers repeatedly.
Many employers now record the names of candidates who have applied previously and if there is no job you will be rejected.
Often the reason for the rejection is not recorded so when a job comes up and you apply again you will show as having been already rejected and so will be rejected again.
