    SMS Fallback to Voice Notifications SMS Fallback to Voice Notifications

    Did you know that ~40% of the calls through Twilio are to a phone that can’t receive text messages? How many folks haven’t opted into your messaging campaigns that you have phone numbers for?

    Voice notifications enable you to communicate with everyone that gives you a phone number, which helps drive up appointments, reservations, or action. Even if users don’t answer the phone, visual voicemail will transcribe your voice notification and provide a similar result as an SMS. This post will show you how to reach the folks you’re not reaching today with Programmable Voice.

    Store Opt-Out data on Twilio with Functions and Sync Storing Opt-Out data on Twilio with Functions and Sync

    Staying compliant is an important part of your messaging strategy. It ensures that your senders have a high trust level from carriers and, as a result, experience lower filtering and lower risk of being blocked.

    Maintaining a clean opt-out list is one of the key pillars for compliant messaging. The Twilio platform helps you maintain customer trust via automated opt-out management (more here), and it's a great start, but under certain circumstances, opt-out information can be lost. Additionally, Twilio does not yet provide an API to retrieve opt-out data.

    All that's to say: we at Twilio strongly recommend you maintain and store opt-out data yourself. In this blog post, I'll show you how storing opt-out information can be done on the Twilio platform with Serverless Functions and Sync.

    The (new) “ridiculously simple” way to send and receive messages around the world Twilio Programmable Messaging Console

    When we first launched the Twilio SMS API in 2010, we called it a “ridiculously simple” way to send messages around the world. Millions of developers have joined Twilio since then, sending and receiving more than 66 billion messages every year.

    We’re excited to launch a new Messaging Console experience with enhanced Messaging Service features like Advanced Opt-Out and Sender ID Compliance Alerts, and the ability to add WhatsApp senders to a Messaging Service Sender Pool. This is part of Twilio’s commitment to simplify the complexities of global telecommunications for developers. With the Programmable Messaging API, a single API for SMS, MMS, and WhatsApp, you can integrate Twilio with your application and configure software to manage phone numbers, improve message deliverability, handle inbound replies, and maintain privacy, compliance, and opt-out settings.

    At SIGNAL, the Twilio Customer and Developer conference, we shared a new milestone: at peak volume, more than 13,000 SMS are sent every second over the Twilio platform.

    Whether you’re sending one message or a million messages, there are important regulatory considerations to consider. In the U.S., that includes the Telephone Consumer Privacy Act (TCPA) and the newly updated guidelines from the CTIA (the wireless industry trade association). Compliance becomes even more complex when you consider the global regulations that impact the messages our six million developers send every day.

    Which laws and regulations apply will depend on the particulars of your text messaging campaign. This includes where the texts originate, where recipients of your texts are located, where your company is located, the industry you are in, and the content of your text messages. We always recommend consulting with a lawyer to ensure that you’re in compliance with …
