Twilio Heightened Awareness Period (HAP) – November 1, 2024 – January 5, 2025
Between November 1, 2024, and January 5, 2025, Twilio will enter a Heightened Awareness Period (HAP) to help ensure reliable message delivery during peak traffic times, such as the U.S. presidential election, Black Friday and Cyber Monday.
During this period, message sending rates to U.S. destinations will be monitored and may be limited at the account level for toll-free, short code, and 10DLC numbers.
Accounts that send high volumes of messages from short codes or toll-free numbers may be temporarily migrated to Market Throughput during the HAP; you will be notified via email if your account is affected. Otherwise, your account will continue to operate under your usual throughput levels. Market Throughput does not affect 10DLC numbers, which will continue to live on Account Based Throughput.
For more information on how your throughput limits may be impacted and what actions to take, please contact your account team or Twilio support.
