Plivo’s message delivery monitoring systems evaluate the delivery rate of inbound messages every 15 minutes. We calculate delivery rates of all inbound message received for your account in the last hour. An alert is triggered if the percentage of undelivered messages is more than 5%.
At 11:00, we'll evaluate the delivery rate of inbound messages received between 10:00 a.m. and 11:00 a.m.
If the delivery rate is less than 95%, we'll send an email alert to your configured email address.
Note: For inbound messages, the validity of an evaluation period is assessed only if at least 10 inbound messages were processed during that one hour. For cases where the number of messages is less than 10 no email alerts are triggered.
