Always date your letters, and make sure that you spell the persons name correctly. If you are unsure, call reception and ask for the correct spelling. I am amazed at how many people send me letters with my name spelt incorrectly.

Use clear headings and subheadings. A well constructed letter is much easier to understand.

Use proper spelling, grammar and punctuation - A well written document says a lot about you. Most software has a "check spelling and grammar" function. Make sure that you always use it.

Plan your letter and decide what you are trying to convey before you start writing. It's a good idea to make some notes, before you start writing the letter.

Be concise and to the point. Use the minimum number of words to convey your message. Try and use simple words that everybody can understand. Try to keep the recipient in mind when writing, especially when writing to someone overseas.

Do not use technical terms or jargon, unless absolutely necessary. Your reader might not be familiar with them.

Space out your letter. This makes the message easier to understand. Start a new paragraph whenever you can as a well spaced out letter is easier to read and understand. It is a lot easier on the eye!

Keep templates, for standard letters. I find that over time my templates improve as I make minor, but significant changes, to the wording and style.

Keep your humour for your telephone conversations. Jokes can easily be misinterpreted in written communication.

If your message is very detailed, it might be simpler to break it down into two letters. Send the first letter and follow it with a phone call to make sure that the message is understood before sending the second part.

Always be polite. Make sure that you ask or request, rather then demand. Don't use informal terms in the beginning of your relationship. You can start being less formal once a relationship has been established.

Answer all correspondence quickly and clearly. Often, in business, the other party could lose interest if they do not believe that they are important to you, or if another business responds first.

Never use shortcuts! You are not sending a text message.

Make a copy of any written correspondence and file it away for future reference.

Once you have written the letter, read it carefully and think about the message you are trying to convey, before posting or hitting the send button.
