Failing to send to all contacts associated with Campaign

Dear Customers,

Our technical team has resolved the issue. The root cause was related to an unexpected issue during the rebuild of an underlying service, which disrupted scheduled message delivery. This issue affected campaign sending within the following time window:

• Incident start time:
19-05-2025, 13:00 AEST until 20-05-2025, 22:18 AEST (Interrupted scheduled messages)
20-05-2025, 22:18 AEST until 20-05-2025, 12:38 AEST (Messages delayed)

• Incident Resolved time: 20-05-2025, 14:56 AEST

Impact:
• Campaigns sent during this time may not have been delivered as expected.
• API messages using scheduling were likely impacted, resulting in delays or failures.
• Broadcasts using staggered sending, SOAP, API wrappers, and other services that support scheduling.

Recommendation:
We recommend reviewing any campaigns sent during this period and resending any that may have been affected.
You can follow this guide - https://support.messagemedia.com/hc/en-us/articles/4413634728975-Reporting-on-Campaigns
to review your campaign reports and identify if your campaign was impacted.

We apologise for the inconvenience and appreciate your understanding.

A fix has been implemented and we are monitoring the results.

The issue has been identified and a fix is being implemented.

We are continuing to investigate this issue.

We are currently investigating an issue in which customers are unable to send their messages to all contacts associated with a campaign ID. End users will see the total number of contacts within Messaging → Campaign reports display the correct number of contacts they intended to send to. However, once the campaign is loaded into, the reporting is inaccurate showing a lower number of contacts than what the previous screen displayed.
