Plivo’s message delivery monitoring systems evaluate the delivery rate of inbound messages every 15 mins.The delivery rates of all inbound message received for your account in the last 1 hour is calculated. An alert is triggered if the percentage of undelivered messages is more than 5%.


For example: 

    - At 13:00, delivery rate of inbound messages received between 12:00 PM to 13:00 PM is evaluated.

    - If Delivery rate is less than 95%, an email alert is sent to your configured email address. 


Note: For inbound messages, an evaluation period is only considered valid if at least 10 inbound messages were processed during that 1 hour. For cases where number of messages are less than 10 no email alerts are triggered.
