解説
問 1
Incorrectア
Addresses put in the To field are displayed to all recipients. If 100 addresses are lined up in the To field at once, the members end up able to see one another's email addresses, which amounts to a leak of personal information. If the questionnaire is to be distributed to everyone at once, Bcc should be used; this way of sending lacks consideration for the recipients.
Incorrectイ
If a large file such as introductory material is attached and sent as it is, it eats up the recipient's data usage, download time, and mailbox capacity, and sometimes it cannot even be received because of the server's capacity limit. Consideration such as compressing the file before sending, splitting it, or telling the recipient the URL of a file transfer service is needed; sending it uncompressed does not take the recipient's burden into account.
Incorrectウ
Addresses put in the Cc (carbon copy) field are also displayed to all recipients. If several customers other than the person who asked the question are lined up in Cc, the customers come to know one another's addresses. Moreover, it also means sending those customers a reply email that they did not ask for. If the same content should be conveyed to other customers as well, Bcc should be used, or it should be sent as a separate email.
- エ
正解 The correct answer is エ. Addresses put in the Bcc (blind carbon copy) field are not shown in the mail headers that the other recipients receive. Therefore, even when the URL of the special-project webpage is announced to several customers at the same time, the customers do not come to know one another's email addresses. A customer's email address is personal information, and making it knowable to a third party without the person's consent is inappropriate, so using Bcc is the basic practice for broadcast mail that sends the same content at once to people who are not acquainted with one another. From the standpoint of consideration for the recipients, this is the only choice that causes neither an address leak nor an extra burden.
ここがポイント
- The difference between To, Cc, and Bcc: To is the main destination and Cc is the party to whom a copy is sent for reference, and the addresses put in these two fields are visible to all recipients. Only the addresses put in Bcc are not displayed to the other recipients, so Bcc is used for broadcast mail that sends the same content at once to people who are not acquainted with one another.
- An email address is personal information, and putting it into a state where others can see it without permission amounts to a leak. Consideration for the recipients includes not only refraining from exposing addresses to the other recipients but also not putting pressure on their line or mailbox with a large attached file.
