Fast Information Distribution
Threema Broadcast is your tool for fast, secure, and targeted one-to-many communication. With the click of a button, you send text/image messages, files, and polls to your entire workforce or to specific departments.
Examples:
Messenger Newsletters
Threema Broadcast’s feeds bring the popular concept of newsletters to instant messaging. You provide separate feeds for different topics, and your employees (or external parties) subscribe to the feeds that fancy their interest. This way, everyone gets exactly the information they’re looking for.
Examples:
- Threema Channel: A service that informs Threema users about app updates and other news related to Threema.
- Press releases from the city of Bern: The people of Bern can receive the city administration’s news directly in Threema.
- Internal information distribution: Various Threema Work customers use messenger newsletters to complement existing news channels. This way, employees can choose to where to receive news.
Business Continuity
Outage of the internal IT infrastructure is a serious threat with profound repercussions. It can occur at any time without warning, and not even the most ingenious measures offer complete protection. If the IT is down, neither email nor VoIP work, and the question is how to maintain seamless communication in this critical situation. The answer is Threema Broadcast, which can, in combination with Threema Work, ensure secure communication even in this inconvenient scenario.

Interactive Chat Bots
Chat bots allow you to create information retrieval systems that enable your users to get predefined answers to their questions right in Threema. For example, you can create a knowledge base or make schedules available. Users simply enter a command and instantly receive the predefined answer as reply.
Central Group Management
Group chats created in Threema or Threema Work can only be managed by their creator. Threema Broadcast, on the other hand, supports central groups, which can be managed manually or automatically using the API. This is to say that a group’s management can be carried out by multiple administrators and without a mobile device. Furthermore, group members can be added automatically, for example.
Employee Engagement
In order to achieve employee satisfaction and to make sure that employees identify with the organization, it’s necessary that internal communication reaches the entire staff. Instant messaging is the ideal channel for this purpose because employees without a computer or those who primarily work off-site are also easy to reach this way.
Threema Broadcast is the ideal tool for managing your messaging communication. Versatile features allow you to target employees in the most suitable way.

FAQs
Threema Broadcast is a web interface that allows for convenient top-down communications via Threema. Use Threema Broadcast to communicate with employees, customers, and third parties.
Besides classic distribution lists and central groups, where you add and manage the recipients yourself, Threema Broadcast also offers feeds and bots. Feeds are dynamic newsletters; users can subscribe and unsubscribe at any time. Bots allow to conveniently retrieve information via Threema.
Both feeds and distribution lists are meant for top-down communications.
As far as distribution lists are concerned, you decide who the recipients are. You can add and remove Threema IDs to distribution lists at any time.
Feeds are similar to newsletters. Users can subscribe to and unsubscribe from feeds on their own. As Broadcast administrator, you can also subscribe and unsubscribe users from feeds. A feed’s blacklist allows to prevent certain users from subscribing to the feed.
Activate Private Broadcast to prevent external users from subscribing to feeds.
Threema Broadcast allows to centrally create and manage group chats. These chats can be managed directly from the Threema Broadcast interface on a desktop computer. Messages sent to such a group chat will also be sent to the Threema Broadcast server since the respective Broadcast ID is also a group member. However, if the setting “Save chat history” (see below) is disabled, the server will discard incoming group messages right away.
Groups can contain up to 256 members. To send messages to more recipients, please use feeds and distribution lists.
Save chat historyTo receive incoming group messages in Threema Broadcast, enable “Save chat history”.
By default, “Save chat history” is disabled. When enabled, the group’s name is prefixed with a cloud icon (“☁️”), which serves as permanent indicator to let group members know whether the group chats’ contents are centrally stored or not. If this setting is changed, all group members will automatically be notified.
Please note that it’s currently not possible to receive media and files, only text messages.
Querying group settingsMembers of centrally managed group chats can send “profile” to the relevant Broadcast ID to query the “Save chat history” setting.
Regular groupsPlease note: The “Save chat history” setting does not affect groups created in the app. All groups created in the app are managed in decentralized manner, and only group members have access to the chat history, nobody else.
Currently, the sending of text / image and file messages (50MB) is supported. At this time, it is not possible to create polls using Threema Broadcast.
