Difference between 送信 and 送付


Both kanji has a similar meaning that mean to send or transmit.

But I wonder which and when the kanji should be used.




Basically, 送信 is used with intangible objects (signal, data, information,
etc.), whereas 送付 is used with tangible objects (paper letters, books, goods,
products, etc.).

When you send something electronically as emails or downloadable files, 送信 and
送付 are both used. Whether to use 送付 depends on how strongly the speaker feels
it is a "thing" — perhaps IT professionals tend to prefer 送信, and elderly
conservative businesspeople tend to prefer 送付.
