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)
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 organizations. Contact us if you’d like it enabled for your Mustr account.
Understanding Delivery Buckets
After sending a Mustr, the response screen will show two main sections:
ANSWERED
Answered: The message was opened and responded to or acknowledged.
Seen: The message was opened but not yet acknowledged or answered.
AWAITING
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: 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.

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
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).
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.
Tip: Enable Notifications
App users with notifications disabled may miss messages. Encourage your team to follow this guide to enable them:
