The amount of messages you can send differs by plan.
You can send up to 1,000 messages a month.
The number of messages sent is calculated as the number of speech balloons sent on LINE multiplied by the total number of friends you have on your account at that time (excluding those that have been blocked).
Example: If a LINE@ account sends 3 messages (3 speech balloons) × 400 valid friends on the account = 1,200 messages
In the above example, the total number of messages exceeds the 1,000 message limit for a free plan and cannot be broadcasted. In this case, you will have to either decrease the number of messages or switch over to a paid plan.
Depending on the number of valid friends on the account, you can choose from multiple plans.

LINE@ offers a feature that allows you to reserve messages for sending later. Just create the message you want to send in advance and then set the date and time you wish to have it sent.
Note: It may take a few extra minutes to send the messages, depending on server conditions at the time.
Only users that added your LINE@ account as a friend will receive broadcast messages. When messages are broadcast, push notifications are sent out and appear on the Chats screen, making them easy to notice.
Notifications are not sent out for Home posts but are viewable to all LINE users, even if they haven’t added your account as a friend. You can expect your Home posts to reach a broader audience as users that viewed it can also share it with others.
With normal messages, you can send emoji and images in addition to text, but you cannot send videos. However, you can attach videos to messages by using the Coupons & Promotions feature.
Coupons & Promotions cannot be created using the LINE@ app, so please use the LINE@ Manager for PC instead. Please note you will need to upload the video to YouTube or another site and then set the URL on the Create Promotion Page screen.
You can check how many messages you have remaining by following the steps below.
From the app version of LINE@
Select an account from the account list > Broadcast > check Remaining messages.
From the LINE@ Manager for PC
Select an account from the account list > check the number next to the broadcast icon on the top of the screen.
