Mail order is a term that has been in use for a long time to describe a method of shopping where customers place orders by mail and receive their purchases through the same channel. However, as the world has moved towards e-commerce and online shopping, the term mail order has become somewhat outdated. Alternative synonyms for mail order include remote shopping, catalogue shopping, and distance selling. In recent times, phrases such as online shopping and e-commerce have replaced the traditional term mail order. Nevertheless, the concept of ordering products remotely remains popular, and there are various ways in which customers can do so, including via phone, email, text message, and social media.
