A request letter is a letter requesting either information or a favor. There are a variety of things that can be requested of when writing a request letter. A good request letter will usually be concise and to the point.
A hard-copy request letter should be written in the business letter format, while an email should be sent in the same format but without the heading (your return address, their address, and the date).
Request Letter Writing
In the opening paragraph, briefly introduce yourself and let the recipient know why you are writing to them.
In the next paragraph, tell the recipient what you are requesting of them along with any pertinent details that would help them to fulfill your request. If you need your request filled by a certain date, be sure to let them know in this paragraph.
In the closing paragraph, thank the recipient for their time/consideration and provide your contact information (if applicable).
