Sometimes messages do not reach supporters. This may be due to temporary network conditions or permanent number issues. 

Mobile Messaging automatically omits numbers that repeatedly bounce to help prevent messages from being flagged as SPAM. 

After three failed delivery attempts, numbers may be marked as opted out or unknown depending on carrier response. 

There are two types of bounces: 

  • Hard Bounces – permanent issues (invalid number, not SMS-enabled) 

  • Soft Bounces – temporary issues (network error, insufficient prepaid credit) 

After three hard bounces, the number is marked Opt-out. 

After three soft (or mixed) bounces, the number is marked Unknown. 

 

The Mobile Messaging Performance Report helps you compare all your efforts or learn more details about contacts who received an individual message. In the summary of this report, you can track: 

  • Total Message Parts - The total message parts that were attempted for Broadcast Messages 

  • Delivery Rate - Phone numbers that successfully received a message divided by the number you attempted to reach 

  • Unique Click Rate - Unique links clicked per message divided by the number of messages delivered 

  • Conversion Rate - Number of form submissions from your mobile messages divided by the number of messages delivered 

  • Contributions - The number of contributions made as the result of your efforts or individual messages 

  • Amount Raised - The sum of the contributions as a result of your message or messages 

  • Avg. Contribution - The sum of contributions received divided by the number of contributions 

  • Hard Bounce Rate and Hard Bounces - Shows the count and percentage of phone numbers that were unreachable 

  • Soft Bounce Rate and Soft Bounces - Shows the count and percentage of phone numbers that could not be reached due to a temporary issue
