A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

What is High-Throughput Toll-Free SMS and MMS?

"High-Throughput Toll-Free" refers to increasing the SMS and MMS sending rate of a US/Canada Toll-Free number. By default, a Toll-Free number can send messages to the US/Canada at a rate of 3 MPS (message segments per second). However, this sending rate can be increased to accommodate rapid high-volume sending. For more information, see Toll-Free SMS and MMS messaging throughput (MPS).
