Threema Broadcast is the tool for versatile, secure, and straightforward top-down communications.
- Use feeds and distribution lists to send messages to any number of recipients, and turn Threema into a powerful newsletter channel. While users can subscribe to and unsubscribe from feeds, you manage the recipients of distribution lists yourself.
- With bots, you can create interactive information-retrieval systems that allow your users to quickly get the answers they are looking for.
- Manage central group chats together with any number of co-administrators, and participate in the group discussion right from your PC.
Threema Broadcast is included in the Professional price plan. The number of Broadcast recipients corresponds to the number of Professional licenses. For Example: If you have 80 Professional licenses, there are 80 Threema Broadcast recipients available.
