邮件

📮✉️ 邮件 = post + item (邮 post/mail + 件 item/piece)
邮 means post or mail (the postal system), and 件 is a measure word for items or pieces. Together 邮件 literally reads as post-items, covering letters, parcels, and now email too.
邮 — 由 (cause) + 阝 (city radical 邑)
邮 means 'post, mail.' The right-side 阝 derives from 邑 (city/settlement), pointing to relay stations along roads. The simplified form pairs this with 由, which here mainly carries the sound. Historically 邮 referred to the courier posts where messengers changed horses to relay official messages.
件 — person radical 亻 + ox 牛
件 combines the person radical 亻 with 牛 (ox). Originally it referred to dividing or counting items, with oxen being valuable units of property to count. It came to mean a measurable item or matter, and today serves as a measure word for things, documents, and affairs.
