"Case study" Tasks

3.      Date:
Adding date in the letter is necessary whether you are writing a formal letter or informal one. Formal letters are official way to communicate with officials so it needs to be send out with date to eliminate any future misunderstanding or error but informal letters also need to be send with date just to make sure that there won’t be any conflict in the future.

4.      Write the name of the recipient:
When you are writing a formal letter it’s very important to put the name of the person you are writing the letter to. You write the name on the first line, his designation and company name on the second line, street address on the third line and city name and ZIP code on the fourth line. When it comes to an informal letter, there is no need to do that. You don’t have to put the name of your friend of spouse bellow the date because it’s just a formal part.
