Changes to Twilio’s Messaging API Response Headers have been Cancelled

The change we announced in March 2022 to API response headers for all SMS and MMS messages sent via Twilio’s Messaging APIs has been canceled. The updates to our terms and policies, which were jointly announced with the potential pending content verification API response header change, are unaffected by this announcement and remain in effect.

Twilio continues to strive for high message deliverability and to keep consumers safe. Thank you for doing your part in promoting trusted communications by ensuring your compliance with Twilio’s Acceptable Use Policy and Messaging Policy and securing proper consent from senders and recipients before messages are sent.
