Motivation letters or letters of encouragement are designed to stimulate the reader to take action to fix a specific problem outlined in the letter. These letters are frequently part of an effort to raise funds or recruit volunteer participants. Personal motivation letters are sent to a specific individual to encourage them to take on the obstacles in their life.
A typical motivation letter is sent to a list of contacts that have previously expressed interest in the organization. It outlines a need, a way for the reader to satisfy the need and maintains a positive tone. A standard format is, "We are very excited about our upcoming event to benefit the XYZ Charity. There are still opportunities to sponsor the headline events for a nominal fee. All proceeds support the cause. We hope to see you at the event and look forward to gaining additional sponsors." The tone should remain upbeat while encouraging the reader to get involved.
The term "motivation letter" is also used when referring to a cover letter that accompanies an employment application. These letters are tailored very specifically to reflect why the applicant would be an ideal fit for the position, and while they remain concise, they are meant to be persuasive.
