This phrase, commonly used in electronic correspondence, indicates that the sender is acting as a representative for another individual or entity. It prefaces the stated sender’s name when someone is sending a message not from their own capacity, but in the stead of someone else. For example, an executive assistant might send a message to a client, signing their own name with the added notation to clarify that they are sending it at the direction of their superior.
Using this expression clarifies the sender’s role and intent, ensuring transparency and preventing potential confusion regarding authority and responsibility. It’s a convention steeped in professional communication practices, providing context to the message and maintaining a clear chain of communication. historically, similar phrases were used in formal letters to delineate agency and representation; the contemporary usage in electronic mail retains the core function of this practice.
