What is Broadcast Messaging?

Broadcast messaging or bulk messaging is a method of delivering information to many recipients simultaneously. Businesses use broadcast messages to keep their contacts updated about store closures, unexpected delays, upcoming promotions and more.

Broadcasting was primarily carried out on channels like email and SMS but these days, bulk messaging via instant messaging is becoming more popular.

SMS messages have limited characters, no rich media and geographical restrictions, while emails tend to be ignored or sent to spam. Instant messaging channels like LINE Official Account, Telegram or Viber solve these issues and provide added benefits.

Messaging apps on everyone’s phones and push notifications mean businesses get their contacts’ attention immediately. With video and image support making messages more engaging, it’s easy to see why their open rates are a 600% improvement over emails!

Next, we’ll go over the reasons why we would use LINE Official Accounts over other channels for broadcasting.

Here are the benefits of using a LINE Official Account to broadcast:

  • With over 182 million monthly active users globally, LINE has high usage in certain regions such as Japan, Taiwan, Thailand and Indonesia. If your audience uses LINE as their primary messenger, it would be the wisest choice.
  • LINE lets businesses of any size create LINE Official Accounts to communicate with their contacts
  • You can send broadcast messages at any time to contacts who have added you as a friend on your LINE Official Account
  • Broadcast messages can have different types of content such as images, videos and more. Interesting content is better at capturing your audience’s attention while increasing the chances of them responding or taking action.

Next up, let’s go over some things you should know about the channel before you start using it to send broadcasts.

What You Should Know About LINE Broadcast Message

Like other business messaging channels, you won’t be able to import existing contacts to your LINE Official Account. You will need to build up your contact list by getting contacts to add you as a friend and send you the first message.

Fortunately, LINE has tools and features like chat links, QR codes, website buttons, in-app search and LINE ads to make getting new contacts easier. QR codes are great for physical locations like retail stores, while chat links can be used on online platforms.

When a contact scans your QR code or clicks on a chat link with their phone, they are brought to your LINE Official Account inside the LINE app. On desktop, chat links send them to a page with a QR code which they can scan with the LINE app on their phone.

Likewise, website buttons work exactly like chat links, with the added benefit of the familiar LINE green branding. In-app search allows customers to find you from within the app, and LINE ads put you on the feeds of your target audiences.

While it’s free to create a LINE Official Account, the accounts have different limits based on the region they are created in. Each account has a set amount of free messages that are renewed monthly.

Free plan accounts have to strictly adhere to this messaging limit since they don’t have the option of paying for additional messages without upgrading to a higher tier. Paid plan accounts can exceed their limits with fees imposed for each extra message sent.

Different Ways to Send a LINE Broadcast Message

There are two ways for businesses to send a LINE broadcast — through the LINE Official Account Manager or by connecting their LINE Official Account Messaging API to a central inboxing service like
