What happens when a Powerpack SMS/MMS recipient replies with an opt-out keyword?

When an SMS/MMS recipient replies with a STOP keyword:

  1. The subscriber is added to the suppression list for the source number that was used to send out the SMS/MMS. 

Subsequent messages from that source number to the subscriber are blocked by Plivo. The message is marked as “failed” with the Plivo error code 200. The block is removed only if the subscriber texts an opt-in keyword to the Plivo number. 

  1. If the SMS/MMS was sent via Powerpack, then the recipient's phone number is also added to the suppression list for the Powerpack. 

Subsequent messages from that Powerpack to the subscriber are blocked by Plivo. The message is marked as “failed” with the Plivo error code 200. The Powerpack level block is removed only when the subscriber texts an opt-in keyword to any Plivo number associated with that Powerpack.
