(1) Check the sending addresses with plural people (Double-check)
Confirm the sending addresses at the final stage with plural people.

(2) Protect the e-mail addresses.
In case you need to protect receiver’s addresses, while sending an e-mail to plural receivers, follow the steps below.

a. Place the sending addresses in “Bcc”.
b. Make a mailing list if necessary. To avoid sending a reply to all receivers, place the mailing list in “Bcc”.
c. In case you want to send a large number of e-mails to each receiver at once instead of treating them as “Bcc”, there are settings or additional functions which allow you to insert e-mail address individually.
Please refer to the following page for setting etc.
