What does sender mean?
A sender is a person or thing that sends a message, letter, package, or other communication. The term applies broadly to letters and parcels, but it is especially common in email, messaging, and telecommunications. A digital sender may be identified by a name, email address, phone number, account, or device. The word is neutral in tone and usually describes the source of a communication without implying whether that source is trustworthy or unwelcome. In everyday use, “the sender” often refers to the person responsible for initiating an exchange: “Please reply directly to the sender.” In technical and administrative contexts, it may identify the originating address, device, or system. The distinction from “recipient” or “addressee” is straightforward: the sender originates and transmits, while the recipient receives and the addressee is the person intended to receive the message.

The plural is standard when referring to multiple people or systems that originate communications.
"The filter blocked messages from several unknown senders."
In every message, a sender provides the starting point—and sometimes the first clue to who is behind it.
