How Mustr Ensures Message Delivery
Mustr is built for every environment, including those with unreliable connectivity such as military bases with poor cell signal and limited WiFi. To increase delivery success, Mustr messages are sent through multiple channels:
SMS (Text Message)
App Push Notification
and Email (when enabled)
Note on SMS Links:
SMS messages include a secure link that allows team members to respond without logging in. These links now expire after 30 days for improved security and timely responses.
Learn more about SMS link expiration.
Automatic & Manual Follow-Ups
If your message doesn’t reach everyone on the first attempt, Mustr provides options to retry delivery:
Remind All
Use the Remind All button to resend the message to anyone still in non-delivered status buckets.
In some cases App users will receive a text message when sent a reminder.
Ensure Delivery (Beta Feature)
Ensure Delivery is an automatic follow-up that re-attempts delivery 10 minutes after the original message is sent — targeting only those who didn’t receive it.
⚠️ Ensure Delivery is not enabled for all commands. Contact us if you’d like it enabled for your Mustr account.
Notify New Members
If new members are added to a team after a message has already been sent, you’ll see the following prompt on the message screen:
Notify new members?
# new member(s) joined teams related to this message.
Notify them?
Tap the Notify button to send the original message only to the newly added members without resending it to the entire team.
This ensures late-added personnel receive important communications without creating duplicate notifications for existing recipients.
Understanding Delivery Buckets
After sending a Mustr, the response screen will show two main sections:
ANSWER DETAILS
This section will display the members that have opened and responded your message.
SEEN: The message was opened but not yet acknowledged or answered.
AWAITING RESPONSES
This section will display the members that have not yet opened, responded, or received your message.
Delivered
Delivery Errors: The message failed to send. Click into this bucket to see user specific error messages such as:
SMS (text) Opt-Out
Number Out of Service
Unreachable Destination Handset
Notifications Disabled
Awaiting Cell Signal: The message hasn’t yet reached the user’s device. They may be out of range or offline.
Having users enable their Notifications settings is KEY to receiving Mustr notifications. Here are the steps: (NEW LOOK) Adjusting Notifications
SMS Opt out users who have typed "STOP" in the text messages can re-enable them by texting "START" to 833-949-3191.
How to Review Mustr Responses
To review responses for your Mustr (Broadcast, Status Check, RFI, or Direct Message):
Open the Messages page in the bottom navigation menu.
Click into the relevant Direct Message, RFI, Broadcast, or Status Check Mustr.
View the breakdown of:
Answered: users who responded or saw the message
Awaiting: users who haven't responded or saw the message, including those with delivery issues
Only Org Leaders can view all Mustr results across the command. Team Leaders can only see Mustrs sent to their team.
Bulk Actions for Response Management
You can perform bulk actions on users in any response bucket, whether they’ve answered, seen the message, had a delivery error, or are still awaiting delivery.
Answer on Behalf of Team Members
Tap on the double arrow icon to submit a response for selected users. This is useful if they communicated their answer via phone, email, or in-person (e.g., lost phone or weak cell signal).
Note: If you select multiple users at once, the same response will be submitted for all of them. To provide different responses, update each user individually.
Add to Team / Create New Team
Group selected users based on shared responses or statuses. This is great for follow-up targeting.
Example: If 12 users gave the same response, quickly group them into a new team to send a tailored message.
To add to an existing team, tap the single person icon.
To create a new team with the selected member(s), tap the double person icon.
Tip: Enable Notifications
App users with notifications disabled may miss messages. Encourage your team to follow this guide to enable them: (NEW LOOK) Adjusting Notifications
