How does Plivo determine that my outbound delivery rates are low?

Plivo's alert system monitors critical error codes and generates alerts if there's a dip in the successful delivery of messages to a particular destination. Refer to our troubleshooting guide for more information related to a particular error code (such as 30, 40, 160, etc.). Every 15 minutes, we compare the delivery rates over the previous 60 minutes to  the average delivery rate over the previous seven days. We will email you if we  detect significant variance.

Here are examples of alert messages. 

  • At 13:00 on January 10, 2021, our systems assessed the delivery rate for messages processed from 12:00 to 13:00 on the same day towards the US. Let's say the calculated delivery rate is 70%.
  • This rate is then compared with the average delivery rates towards the US over the past seven days (January 4 to 10), for the 12:00 to 13:00 time period each day. Assume the average delivery rate from these data points is 95%.
  • The observed drop in delivery rate to 70% represents a significant decrease of 26.3%. If this reduction is attributed to the error codes monitored by Plivo, it would trigger a delivery degradation alert to the designated email address.

Note: For outbound messages, an evaluation period is considered valid only if there are at least 100 outbound messages to a destination country.

These alerts help you take immediate action to remedy any issues that may cause your messages to go undelivered.
