IZ*ONE Private Mail is an app where fans can pay to see the messages a specific member leaves. A dedicated WIZ*ONE recently tallied the number of messages that each member has left since the app launched six months ago.
As you can see from the chart above (courtesy of @MaddieIZONE), Hitomi communicates most regularly with fans while Wonyoung and Hyewon are tied with the least.
Sakura also gave her verdict on some of her fellow member’s private mail content:
Wonyoung’s mail is fishing, Hyewon’s is random trivia and Chaeyeon posts cute pictures.
So if you were going to purchase access to a member’s private mail, Hitomi gives the best value for money but perhaps the other members provide quality over quantity?
