Error 30001

Product: Programmable SMS

ERROR - 30001

Queue overflow

Twilio queues messages based on the sending rate of a sender or an account. For example a US long code number can send one message segment per second.

Messages can only be queued for 4 hours and then they automatically fail. You can monitor the length on your queue via the Queue Insights dashboard.

For more information please view this FAQ.

Possible Causes

  • You tried to send too many messages too quickly and your message queue overflowed.

Possible Solutions

  • Try sending your message again after waiting for some time.
  • Try using a Messaging Service.
  • Talk to Twilio Sales about getting a Short Code number that allows you to send more messages per second.
