Mustr lets you send three main types of secure messages (called Mustrs) to your entire command or targeted teams. This guide explains the differences between each type and how to use them effectively.
Table of Contents:
Permissions
Only users with the role of Team Leader, Org Leader, or Org Messenger can send Mustr messages. Regular team members and Org Admins can only view and respond to messages.
Broadcast Messages
Use Broadcast Messages to quickly share announcements or updates, see delivery, viewership, and acknowledgments.
Common Uses:
Weather delays and Gate closures
Security alerts, Commander's messages
Share general information about facilities, functions, or opportunities
How to Send a Broadcast Message:
Tap the message icon in the bottom-right corner of the Mustr landing page.
Select Broadcast.
Type your message and select the relevant team (Optional: Attach a file or schedule your mustr, if needed).
(Optional) Set a response deadline (soft or hard) to track acknowledgments and get notified if someone hasn’t responded in time.
Recipients will see an Acknowledge button along with the message.
Status Checks
Status Checks are quick yes/no prompts typically used for checking wellbeing or presence.
Common Uses:
Daily roll calls
Post-incident check-ins
Rapid wellness checks
How to Send a Status Check:
Tap the message icon in the bottom-right corner of the Mustr landing page.
Select Status Check.
Select the relevant team.
(Optional) Set a response deadline (soft or hard) to follow up with non-responders.
Recipients can add a comment along with their yes/no response before submitting.
Request for Information (RFI)
RFIs allow you to ask one or more structured questions and collect detailed responses from individuals or teams.
How to Send an RFI:
Tap the message icon in the bottom-right corner of the Mustr landing page.
Select RFI.
Add the relevant team and Add your question(s).
Choose the appropriate question type (see below). Tap Add to RFI and send your RFI.
(Optional) Save frequently used questions as templates.
Question Types:
Freeform – Open text response. Use for detailed input.
Numeric – For number-based answers (e.g. “How many vehicles are needed?”).
Date – For selecting a specific date.
Multiple Choice – Set options for users to choose from (e.g. “T-shirt size: S, M, L”).
Saving RFI questions for later use
Some RFI questions might be relevant in the future, or you might want to use them as a recurring question. To save a question for future use:
Select “Save answer as Template” when creating the question.
Later, choose it from the Question Bank during RFI creation.
Getting notifications for RFI Responses
To receive a notification on Yes/No questions, you can choose to be notified only when a specific answer is selected. This is common when asking for volunteers or wanting an immediate notification if someone is in need.
To customize notifications:
After creating your RFI and adding your question(s), select the answer you want notifications for.
Understanding Deadlines
When sending a Mustr, you can set a deadline to prompt responses within a desired timeframe. There are two types of deadlines you may encounter:
Hard Deadline
Recipients cannot respond after the deadline has passed.
Best for time-sensitive or mission-critical messages.
he Mustr will show as “expired” once the deadline is reached.
Soft Deadline
Recipients can still respond after the deadline.
You’ll still be notified of late responses.
Best for non-urgent requests or ongoing info collection.
You can select a deadline type when composing a Mustr by tapping the deadline options during the message setup.
Deleting a Mustr
If you've sent a Mustr by mistake or it’s no longer needed, you can delete it from the Mustr log. Once deleted, the message is removed from all recipients’ views, and any responses or acknowledgments are permanently lost.
⚠️ Important: Mustrs cannot be edited once sent. Deletion is permanent and irreversible.
⚠️ Only individuals with permissions for the team the Mustr was sent from can delete it.
How to Delete a Sent Mustr:
Go to the Mustr log from the home screen and locate the Mustr you want to delete. Tap on it to open the Broadcast Details. Tap the three-dots (⋮) to select Delete this Mustr.
Confirm the deletion by completing the confirmation prompt.
What Happens for SMS Users?
If someone received the Mustr via SMS and tries to click the link after the Mustr has been deleted, they will be directed to a "Link is invalid" page.
This helps avoid confusion and ensures the user knows the message is no longer available.
THINGS TO KEEP IN MIND:
If you choose to upload a file, you will be able to select files that were previously uploaded to your command's Files tab (under Recent files).
You only upload up to 25MB at a time.
