Happy building!

Twilio is now fully live with Verizon 10DLC A2P's service and carrier fees are in effect. You can read more about the change in our FAQ here.

Starting today, read message status and location message are available to all developers building on the Twilio API for Whatsapp.

• Read message status: When an outbound WhatsApp message is opened by the end user, this will generate a status callback indicating the message was read. Read status will also be shown in the message logs and the Message Resource API. See our documentation for more details.
• Location message: You can now send location messages over Whatsapp, by including the PersistentAction parameter in your API requests. Location message is currently only supported in Session Messages. See our documentation for more details.

Check out our blog post on using these new features to build deeper customer engagement experience via messaging.

In order to keep you in carrier compliance and ensure fair service across all customers, we now have rate limits in place for MMS service. While you can still send messages to Twilio at a rapid rate, the delivery rate for each account is now capped at 25 messages per second (MPS) and for each Twilio long code at 1 MPS.

For time-sensitive messages, we recommend that you keep a close eye on the queue length via Message Queue Insights in the console. You can also find more details on this page.

Advanced Opt-Out gives customers granular control over the end-to-end compliance experience for their customers and users. Customers can now customize opt-in, opt-out, help keywords, and confirmation messages on a global basis with per-country or per-language overrides all within the console.

To help you manage two-way communication with your customers, today we released a new API called Twilio Conversations. Using Conversations, it's easy and quick to build cross-channel messaging applications: SMS to WhatsApp, SMS to Chat, or any other combination. Twilio even exchanges Media for you automatically — no need for webhooks!

Conversations is open to anyone with a Twilio Account. Head over to the documentation to learn more and give it a try.
