Unified Login for SendGrid Marketplace Customers

Fri, 16 Oct 2026 02:00:00 -0400

SendGrid marketplace customers can now take advantage of the Unified Login feature that lets you create a Twilio login for every individual user accessing your SendGrid account. This provides a more secure access pattern with the ability to define permissions for each user instead of a single, shared admin permission set.

When accessing your SendGrid marketplace account from one of the marketplace integrations - Microsoft Azure, Google Cloud, Heroku, or Amazon Web Services - you will be prompted to provide an email address to create your Twilio login. If you already use another Twilio product and have an existing Twilio login, you can use that email address and password for SendGrid access.

This will be rolled out over the next couple weeks for all SendGrid marketplace customers. For more details, see the documentation here.

Webhook Configuration API is now Generally Available

Thu, 15 Oct 2026 00:00:00 -0400

Twilio Cohorts for Native List Building and Bulk Messaging

Wed, 14 Oct 2026 03:00:00 -0400

Twilio Cohorts is now available in Private Beta, providing a set of APIs designed to handle list building, audience segmentation, and bulk execution natively within the Twilio platform. Set up your customer profiles, segment them, and trigger messages using your existing Twilio account.

Twilio Cohorts includes:

Dynamic List Building & Segmentation: Define customer traits and query dynamic audiences directly within Twilio.
Native High-Volume Delivery: Pass a single CohortID when triggering a send with the Twilio Email API or the Twilio Bulk Messaging API (supporting Email, SMS/MMS, RCS, and WhatsApp) without writing custom batching logic.
Unified Execution: Streamline multi-channel workflows and eliminate custom queuing or backend rate-limiting logic.

Coordinating high-volume delivery across Email, SMS, RCS, and WhatsApp alongside your native Twilio data has never been easier.

To request early access to the Private Beta, submit a request form. For API details and technical guidance, see the Twilio Cohorts documentation.

Voice Insights now tags HD audio calls

Fri, 09 Oct 2026 03:00:00 -0400

Voice Insights now tags calls as HD Audio when they connect with the AMR-WB or Opus codec.

Use the tag to confirm your endpoints negotiated what you configured, and to correlate HD usage with transcription accuracy, AI agent performance, and customer satisfaction.

Calls that carry HD audio are tagged as Downsampled when the longest portion of the call connects to a component or another endpoint that does not support HD. Twilio converts the audio to narrowband to keep the call connected.

Both tags appear in the Call Summary in Console, in the Voice Insights REST API, and through Event Streams. You can also filter the Call Insights dashboard by either one.

Learn more in our Call Summary documentation.

RCS messaging now supported on all major Canadian carriers

Thu, 08 Oct 2026 19:00:00 -0400

To start sending branded RCS messages, go to the Twilio Console to create and submit an RCS Sender.

For more information, see our RCS documentation.

Segment Conversation Memory Integration now in GA

Mon, 05 Oct 2026 14:30:00 -0400

The Segment Conversation Memory Integration is now in GA. You can now sync long-term customer profile data, like identity and lifetime value, from Segment into the sub-second recall of Conversation Memory, enabling both AI and human agents to instantly access unified context during live interactions. This eliminates cold starts, reduces repetitive questions, and delivers highly personalized, continuous customer experiences across all channels.

The integration continuously syncs long-term customer profile data, such as identity and historical traits, from Segment directly into Conversation Memory. Customers configure this transfer using either "Memory Sync" to rapidly import their entire profile database or "Memory Destination" to target specific user cohorts via Segment Audiences. During setup, Segment profile traits and identifiers are mapped to corresponding semantic trait groups within a Memory Store. Once active, trait updates flow in real time, allowing AI or human agents to instantly query the Memory Store for up-to-date customer context during live interactions.

To get started, read the Segment Conversation Memory Integration | Twilio, and browse the Conversation Memory (Actions) | Twilio.

Short Codes are now supported in Data Residency for SMS (EU)

Mon, 05 Oct 2026 19:00:00 -0400

Short Code numbers are now supported as SMS senders in Twilio's Ireland (IE1) region for EU data residency. When using this feature, SMS message personal data sent or received via Short Codes is stored and processed in the EU up to the point it reaches Twilio's connections with telecommunications providers.

With this release, the IE1 region supports the following features:

Short Code senders: Send and receive SMS messages with short codes in IE1.
Region Configuration API: Configure short codes for IE1 using the V3 region configuration API.
Short Codes API: Set IE1 inbound webhook configurations using the ShortCodes resource.
Messaging Services API: Add short codes to IE1 messaging services using the service ShortCodes subresource.

To learn more and get started, see the developer documentation.

Voice Insights now shows why carriers block your calls

Thu, 01 Oct 2026 03:00:00 -0400

Voice Insights now tells you why a carrier blocked your call and how to reach that carrier for redress.

The FCC requires carriers that block calls using analytics to return the reason header to the caller. It names the network that blocked the call and tells you how to contact them: a URL, a phone number, or an email address. Until now a blocked call showed you only a 603 response. Now you can see which network blocked it and petition them directly.

The reason header appears alongside Last SIP Response in the Call Summary, in Twilio Console, the Voice Insights REST API, and Event Streams.

If you are seeing a high volume of 603 responses, confirm your traffic is signed with STIR/SHAKEN and registered with Twilio Voice Integrity before you start filing redress requests.

Learn more in our Call Summary documentation.

Batch Transcription Configuration is now Generally Available!

Thu, 01 Oct 2026 03:00:00 -0400

Tune transcription without touching your code: engine, model, language, and destination live in a reusable configuration, so changing any of them is one update that every subsequent transcription picks up. Results are delivered via webhook or stored downstream in Conversation Orchestrator for persisted storage and Operator analysis.

Twilio Video Media SDK for Node.js now in Public Beta

Wed, 30 Sep 2026 19:00:00 -0400

The Twilio Video Media SDK for Node.js is now in Public Beta. Your server-side app can securely join a Video Group Room as a participant and work with decoded audio and video frames directly, so you can run AI and media processing such as transcription, computer vision, or compliance monitoring on your own infrastructure, without the overhead of a headless browser.

Your app reads decoded frames from other participants and publishes frames back into the Room as a virtual camera or microphone. This Media SDK shares the Room, Participant, Track, and Access Token model of the Video JavaScript SDK, so most concepts carry over. Install it from npm as @twilio/video-node-sdk. It requires Node.js 24 or later on x86-64 Linux, and the Media SDK participant counts and bills as a standard Group Room participant.

To get started, read the Video Media SDKs overview, follow the quickstart, and browse the AI/ML example applications.

Account Rate Limits on Content API

Wed, 30 Sep 2026 03:00:00 -0400

What is Changing?

To improve platform stability, endpoint reliability, and system performance, Twilio is introducing standardized rate limits for Content API requests.

Rate limits will be enforced at the account level. Requests exceeding these limits will receive an HTTP 429 Too Many Requests status code.

Rate Limits by Endpoint

Read Operations

Fetch Content (GET /v1/Content/{Sid}): 100 RPS
Fetch Approval (GET /v1/Approval/{Sid}): 100 RPS
List Content (v1 & v2) (GET /v1/Content): 20 RPS
List Content & Approvals (v1 & v2) (GET /v1/ContentAndApprovals): 20 RPS
List Legacy Content (GET /v1/LegacyContent): 20 RPS

Write Operations

Create Content (POST /v1/Content): 100 RPS
Create Content Approval Request (POST /v1/Approval): 100 RPS
Update Content (POST /v1/Content/{Sid}): 20 RPS
Delete Content (DELETE /v1/Content/{Sid}): 100 RPS
Update Content Approval Request (POST /v1/Approval/{Sid}): 20 RPS

What You Need to Do

Implement Exponential Backoff: Ensure your application can handle HTTP 429 status codes by incorporating backoffs and retries.
Audit High-Volume Pipelines: If your service executes bulk script operations (such as creating or deleting content templates in high-concurrency bursts), adjust your client throttling to remain within these thresholds.

Twilio Heightened Awareness Period (HAP) – November 19, 2026 - January 4, 2027

Thu, 17 Sep 2026 02:00:00 -0400

Between Thursday, November 19, 2026 and Monday, January 4 2027, Twilio will enter a Heightened Awareness Period (HAP) to help ensure reliable message delivery during peak traffic times, such as 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. Customers will be notified via email if their account is affected. Market Throughput doesn’t affect 10DLC numbers, which will continue to live on Account Based Throughput.

For more information on how throughput limits may be impacted and what actions to take, customers can reach out to their Twilio account team.
