• ×Incorrectア

  Sending to a company email address that has been made public is permitted as an exception to the opt-in rule (it is an address that the business itself has made public, not a personal address). It may be sent even without prior consent, so it does not become subject to regulation.

• ○イ

  正解 The correct answer is イ. In its 2008 amendment, the Act on Regulation of Specified Electronic Mail adopted the opt-in approach, under which, as a rule, advertising email may be sent only to recipients whose prior consent has been obtained. Choice イ reflects an opt-out style of thinking, namely “once a recipient sends a refusal notice, it is enough to stop sending from that point on”, and sends advertising email without obtaining prior consent. This is exactly the sending method that the current law prohibits, so it could become subject to regulation.

• ×Incorrectウ

  What the Act on Regulation of Specified Electronic Mail regulates is “advertising email”. Email for administrative notice or fee invoicing does not have advertising as its main purpose, so it is not subject to the Act in the first place.

• ×Incorrectエ

  For a party with whom there is a continuing business relationship, sending content about a new version of a product previously delivered is permitted as an exception based on that business relationship. This is a case where obtaining prior consent is unnecessary, so it does not become subject to regulation.
