The most important aspects of written communication include understanding its purpose and defining the intended audience. Ask yourself, what you want the copy to do. Should it inform, prompt a response or entertain? Who will read it and how will the readership affect the tone of voice you choose?
Planning out the flow and identifying what you want to say before you put ‘pen to paper’ is an essential part of creating effective written communication.
Also, when putting words together keep it clear and concise. Avoid jargon, management speak or technical vocabulary that may only serve to alienate the reader.
