If you have sent texts to a group or individual and received an undelivered messages alert, you can check those out by using the "Undelivered Messages" filter in the inbox. 

Once you click this filter, a list of all your undelivered messages will show. You can click on each conversation and hover over the undelivered icon for details on WHY that message was undelivered. 

You can also check your stats on group message you have sent. 

1. Go to Analytics --> Logs 

2. Choose "SMS Outbox (Group)"

3. Select your date range and click "Show"

4. Find the group message you want to check and scroll to the right side and click the analytics icon.

5. Now you can view the group delivery details. 

Here is a list and explanation of the most common errors:
Duplicate Number:
This means there are multiple contacts with the same number in their profile (think husband and wife sharing one number or child profiles using their parent's number as theirs). We would send to the contact marked as primary and skip the duplicate contacts. Credits are not deducted for duplicate numbers. 

Unformatted number checked by carrier lookup: This means the number is not in the correct format. Something is wrong with the number. Most commonly, their number is showing as "0" or "10" because there is no number listed for that person. The first time you send to this person you would be charged credits, but everytime after that, we would skip them and no credits would be deducted. 

Carrier Violation: This means you have sent something that has flagged your message as Spam by the carriers. Credits are deducted.


Skipped: Contact is blocked, opted out, external contact marked as deleted, was marked as unsubscribed by a user, or was a duplicate number. Credits are not deducted.

Here are some additional ones we might received back from the carriers:
Message Delivery - Unknown error: The destination carrier has returned a generic error message.

Unknown destination handset: The destination carrier is reporting the To number is unknown, or no longer in service.

Message Delivery - Unreachable destination handset: The destination carrier is reporting the 'To' number is unreachable - the device is likely powered down, out of the service area, or may not accept your messages.

Message Delivery - Carrier Violation: The destination carrier is filtering out your messages for delivery. This mean the carrier has marked your number as spam. If you send a large amount of bulk group messages, this could happen to you. That is why we recommend using secondary numbers.

Message Delivery - Message blocked: Your message has been blocked from reaching the destination. This mean the carrier has marked your number as spam. If you send a large amount of bulk group messages, this could happen to you. That is why we recommend using secondary numbers.
