Announcements, greetings and letters of congratulations form an integral part of business practice. These can be strictly formal or plainly informal; though the present trend is to make them as informal as possible.

Announcements, whether formal or informal should be pleasing in form and content; and should have a personal air about them. Formal announcements are usually printed or engraved in black ink or a white or cream card, such as those used for invitations to attend formal functions.

While announcements are obligatory on certain occasions such as shifting offices, opening branches and so on, greetings are not so. But greetings are the graces that make business routine tolerable and even enjoyable. They are, therefore, essential to maintaining good relationships between two establishments, between cramployers and employees, between superiors and subordinates and between colleagues.

Some model letters of announcements and greetings suitable from different occasions are given below.
