With reference to 'circular letters', which of the following statements is/are correct? 1. Circular letters are usually addressed to a group of people. 2. Non-standard and customized content is typical of circular letters. 3. Circular letters are used to intimate appraisals and increments of employees within organisations. 4. Circular letters are less cost-effective than personalised and specific recipient-directed letters. Select the answer using the code given below.

Circular letters are written for mass communication and are addressed to a group of people simultaneously, so statement 1 is correct. Statement 2 is incorrect because circular letters are characterised by standardised, uniform content (the same message goes to all recipients), not customised content. Statement 3 is incorrect because appraisals and increments are confidential, personal matters communicated through individual letters, not circulars. Statement 4 is incorrect because circulars are MORE cost-effective than personalised letters since a single drafted message is duplicated to many recipients. Hence only statement 1 is correct.
