A rejection letter is a formal communication sent to inform an applicant that they have not been selected for a position, opportunity, or request. This type of letter is commonly used in various contexts, such as job applications, college admissions, or grant proposals. It typically includes a brief explanation and may offer encouragement for future applications. Rejection letters are important for maintaining professionalism and transparency in the selection process. They help applicants understand the outcome of their submission and can provide valuable feedback. While receiving a rejection letter can be disappointing, it is a standard part of many competitive processes, including those related to employment and education.
