Which HR letter do you need?
An offer letter makes a job offer and sets out the key terms, such as the role, joining date and CTC, for the candidate to accept. The appointment letter follows when they join and records the full terms of employment. An experience letter certifies the role and dates someone worked, and a relieving letter confirms their resignation was accepted and they have been released from their duties. An increment letter records a salary revision, and a promotion letter a new role.
