You can send messages to randomly selected recipients from your friends list by setting a broadcast volume.
Note: If you're filtering friends by demographic, be sure that the number of recipients is set to 50 or more people.
To set a broadcast volume, follow the steps below.
From the LINE Official Account Manager app:
1. Tap the account you want to configure in the Accounts list.
2. Tap Broadcast > Create broadcast.
3. Add a broadcast and tap Next.
4. Turn the Broadcast volume setting ON and enter the number of messages you want to send.
From the browser version of LINE Official Account Manager:
1. Click the account you want to configure in the Accounts list.
2. Click Broadcast > Create new.
3. Check the box next to Set broadcast volume and enter the number of messages you want to send.
The maximum broadcast volume you can set is limited by available demographic data. Since not all user demographics can be estimated, the number of users shown for "Maximum message count" may differ from the number of users listed for statistics displayed on other pages.
Also, the number of users shown for "Maximum message count" may vary over time, as these statistics are updated regularly. Because it takes up to three days for the latest demographic data to be reflected, broadcasts sent with a set broadcast volume are based on demographic data from three days ago.
