Types of cover letterIn response to an advert
Check you meet the requirements of the job outlined, most recruiters advise only applying if you have 90% of the requirements. The other 10% are probably 'nice to haves' rather than 'must haves' anyway.
Don't dwell on what you don't have, highlight your assets.
Use the words in the ad in your letter. Highlight how you have a track record in these areas.
In this instance, there is usually a name provided. If there isn't find out whom it should be addressed to. Make sure you reference the job, where you saw it.
Do your Research on the company - find out what the company does and how your skills could add value to their team.
It could start of with 'Having read you are (mention recent articles on company and why your skills would be of benefit to such a company).
Again, also send the letter to a specific person.

Find out the relevant consultants name that deals with your sector.
