Translation guide
In Japanese, the concept of a 'sender' is usually expressed by the person or entity that sends something, rather than a single abstract noun. The most common way is to use the person who sends (差出人) in postal contexts, or the sender of a message (送信者) in digital contexts. In many cases, the subject of the verb 送る (to send) is used.
The individual or organization that dispatches a physical item via mail or delivery service.
Standard term for the sender of a letter or parcel. Used on envelopes and forms.
差出人の住所を封筒の裏に書いてください。
Please write the sender's address on the back of the envelope.
Literally 'sending person', used for the sender of goods or packages, slightly less formal than 差出人.
荷物の送り主が不明です。
The sender of the package is unknown.
Formal term for a dispatcher or shipper, often used in business or logistics.
発送人は商品の破損について責任を負います。
The sender is responsible for any damage to the goods.
The originator of a digital communication.
Standard term for the sender of an email, text message, or data transmission.
メールの送信者を確認してください。
Please check the sender of the email.
Used for the sender of a phone call, fax, or sometimes messages. Emphasizes the act of initiating communication.
発信者番号が非通知でした。
The sender's number was blocked.
Casual way to say 'the person who sent it'. Used in everyday conversation.
そのメッセージを送った人は誰ですか？
Who is the sender of that message?
The address or details written on an envelope or package indicating who sent it.
Specifically the sender's address.
差出人住所を明記してください。
Please clearly write the sender's address.
Sender information in a broader sense, used in forms or online shopping.
送り主情報を入力してください。

The transmitting end in a communication system.
The sending side or transmitting end, used in technical descriptions.
送信側のエラーでデータが失われました。
Data was lost due to an error on the sender's side.
The source or origin of a transmission, often used for calls or network packets.
発信元のIPアドレスを追跡する。

差出人 is used for physical mail and packages, while 送信者 is for electronic messages. Using 差出人 for an email would sound odd, and vice versa.
In casual conversation, Japanese speakers often avoid the noun 'sender' and instead use a relative clause like 送った人 (the person who sent it). Using 送信者 in a casual chat might sound overly technical.
この荷物の送り主は誰ですか？
Who is the sender of this package?
差出人の名前が書かれていませんでした。
The sender's name was not written.
