Twilio Changelog

Easily verify if you can port-in your desired US local phone numbers to bring Voice and Messaging capabilities from your current carrier to Twilio.

On March 18, 2025, SendGrid updated the information included in email headers to enable customers to utilize Gmail’s Feedback Loop. Previously SendGrid populated the header with x-feedback-id, which limited customer usage of gmail’s feedback id. Now senders will have better resources to identify spam complaints from individual campaigns.

Generative Custom Operators are a new class of Voice Intelligence Language Operators, backed by Generative AI, that support a broad range of sophisticated natural language analysis tasks with a high degree of accuracy. Generative Custom Operators are now available in public beta.

Generative Custom Operators allow you to provide natural language instructions describing what you want to understand from customer calls. These instructions are then fed to a Large Language Model (LLM) along with the call transcript to analyze the customer interaction and provide actionable results.

This feature significantly extends the flexibility, power, and accessibility of custom Language Operators to address a variety of conversational intelligence use cases. Examples include (but are not limited to):

• Call Scoring: Assign an overall score based on agent performance against customized criteria.
• Script Adherence: Evaluate whether agents stuck to the script and achieved their goals.
• Tailored Summaries: Generate call summaries in the format that best fits your business needs.
• Upsell Identification: Use the context of the call to identify high-likelihood upsell opportunities.
• Lead Qualification: Use buying signals to classify leads into categories like 'Hot' or 'Cold'. 

Support for Generative Custom Operators is now available both in the Voice Intelligence Console and via API. Advanced options are also available for JSON structured Operator results and providing training examples.

To start building with Generative Custom Operators for Voice Intelligence, including use case examples and best practices, please see our getting started guide.

SendGrid has implemented a change to correct behavior surrounding invalid email addresses. Previously, mail attempted to invalid email addresses (those without a properly formatted top level domain) were classified as Bounces. Changes implemented today will cause these events being classified as Drops with a reason of Invalid Address. Some customers may notice a slight decrease for Bounce events and increase for Drop events as a result. 

This change more accurately represents the reason the email could not be delivered, maintains better data integrity, and better supports expected feature behavior related to these classifications. Please reach out to our Support Team with any questions.

The new area code overlays below will be introduced in select regions between April and May 2025. While Twilio doesn’t control these rollouts, we’re here to keep you in the loop.

What You Need to Know:

• These overlays will introduce new area codes in regions where existing ones are running out of numbers.

• Twilio may not have numbers available in every affected region.
  
  

Starting April 15, 2025, Segment will enforce a Data Retention and Deletion Policy to align with industry best practices and enhance data governance. This update ensures efficient data management by implementing a structured deletion process for older event data. 

What’s Changing?

• Segment will introduce a rolling data deletion process, where historical event data beyond a defined retention period will be removed on an ongoing basis.

• Data deletion will occur in phases, starting with an initial cleanup followed by a continuous, automated process.

• Depending on customer tier, this policy applies to event data stored in Archives, Object, and/or Profile Data stores.

What You Need to Do

• Review your data needs and assess whether older data is critical for workflows.

• Plan ahead by identifying any necessary storage solutions outside of Segment for data that must be retained.

For additional details on our retention policy, visit our Segment Data Retention Policy Overview or reach out to your Segment account team.

Twilio SendGrid now supports UTF-8 characters in sender and recipient email addresses. UTF-8 character support means senders will have broader access to operate internationally by contacting and sending in all major global languages. 

There are no configuration changes necessary. Emails with UTF-8 characters in the addresses will now be processed like any other email. UTF-8 Characters in email bodies, subject lines, headers and footers were already supported.

Starting March 31, 2025, Twilio SendGrid will begin upgrading Legacy Marketing Campaigns to enhance performance, reliability, and user experience. This upgrade will be rolled out in phases, and customers will experience the update at different times. While most changes will happen behind the scenes, customers will experience a brief service disruption while the upgrade occurs (lasting up to 30 minutes) at some point during a customer’s scheduled upgrade week, which may temporarily limit access to Twilio SendGrid Legacy Marketing Campaigns.

What’s the Impact?

During the brief service disruption, customers will see:

• Temporary system unavailability: Customers will see a brief “System Unavailable” message in the UI while the upgrade is applied.

• Paused scheduled campaigns: Any campaigns scheduled to send during this time will pause and automatically resume once the upgrade is complete.

After the brief service disruption, customers will see:

• A refreshed experience: Customer’s Legacy Marketing Campaigns pages will match the look and feel of new Marketing Campaigns, improving navigation and campaign management.

• API changes: A small set of endpoint behaviors and fields are changing to support system reliability. 

Next Steps

• If customers use Twilio APIs, they should review the updated API documentation and make any necessary changes before the upgrade to prevent disruptions.

• If customers have time-sensitive campaigns, they should consider scheduling them outside of their scheduled upgrade week.

Customers can monitor real-time system status updates on SendGrid's Status Page during and after the upgrade.
