Termination emails are an important tool when it comes to formally ending a business relationship or period of employment. The email should provide sufficient detail to inform the other party that their services have been terminated, as well as the date on which the termination is effective. Termination emails should be written in a respectful and professional manner and should include all pertinent details about the termination. Additionally, termination emails may also include a statement of appreciation for any good work that has been done, but must make it clear that any engaged parties have fulfilled their obligations.
