The term "sendee" is commonly used to refer to the recipient or person who receives something that has been sent, such as a message, parcel, or letter. However, there are a number of synonyms that can be used to describe this individual depending on the context. These include addressee, receiver, recipient, consignee, holder, and client. Each of these words implies a slightly different relationship between the sender and the individual in question, and can be used to add context or nuance to a given communication. Ultimately, the choice of synonym will depend on the desired tone, the details of the message, and the nature of the relationship between the two parties.
