A withdrawal letter is a formal document used to formally retract or cancel a previously made decision, application, or request. Commonly used for withdrawing job applications, academic admissions, or proposals, it includes the reason for withdrawal and any relevant details, such as application numbers or dates. The letter is respectful and concise, expressing gratitude for the opportunity and, if appropriate, indicating willingness to remain in contact for future opportunities. Its tone is professional and courteous, aiming to maintain positive relationships while clearly communicating the retraction.
