Many a times people avoid giving donations not because they do not want do donate but the reason is that they are not sure where exactly will their donated money end up. So, when writing an appeal for donation you have to emphasise and focus on the reason you are asking the donation for. The donation required does not necessarily have to be in the form of cash, it can come through in the form of product, services or even volunteer hours.
You will not need to experiment much with the way a donation appeal is written, keeping it simple and to the point will just work out fine.
The tone of the letter should be formal and there should be no unnecessary details in the body of the letter, keep in as concise as possible. Encourage the reader to donate by stating how will the contribution matter and will be used. Besides being formal, add a personal touch to the letter which would show that you are not just fulfilling a formality by asking but are actually interested in the well fare that will be the outcome of the donation.
Sum up the letter in three straight forward paragraphs, introduce yourself and the organisation in the first one, state the required in the second paragraph and last but not the least, thank the reader for taking out time for reading the letter.
Firstly, introduce yourself and the company, mentioning clearly the cause that you serve. Further on, not taking much time, inform them about the nature of help that you require. Try to attach the cost that has to be incurred so as to make the procedure quicker.
