Dear Mr Swift,
I, Mrs Scarlet, the sales manager of the YBZ mall, am writing this letter to make you aware of certain changes in the sales patch for a period of the next 2 months. The months which are approaching will see an abundance of customers in the mall, because of the presence of the festive season. The sales department wishes to catch the attention of as many customers as possible in this festive season.
The changes to be made in the sales strategy have been discussed in the prior meetings and this letter is just to intimate the onset of these changes. The list of the changes to be made for the initial sales patch is enclosed along with the letter. It is desirable that these changes get implemented as soon as possible. Now, all responsibilities for changes to be done rest on your responsible shoulders and I hope for successful job accomplishment.
