A proposal cover letter is an introductory letter which addresses the question of what the proposal actually embodies. It is an epistolary abstract which gives a brief outline of the proposal and the matter it contains. Since this precedes the actual proposal sequentially, it is very important as it is the first thing to be noticed.
