For the highest readability, start your letter with a short sentence.

 

Message Headline

By breaking up the body of the letter into logical topics, your readers can focus in on the topic that they deem most relevant. Select your wording carefully. Most people scan their emails very quickly. Keep your paragraphs to seven lines or less. If you have more information, include a link to your website where your readers can get further details.

 

Thank your customer, tell them how valuable they are to you, but don't go overboard. Insincerity is easy to spot.

 

Sincerely,
