What is Twilio?

Try Twilio

Twilio is a customer engagement platform that combines communications, customer data, and AI to help you build global messaging and conversation experiences. With API-driven products, you can connect channels like SMS, WhatsApp, voice, video, and email (via SendGrid) and orchestrate them around real-time context. Twilio also offers tools for conversation memory, intelligence, routing, and scalable campaign execution so you can move from first touch to ongoing loyalty.

What is Twilio used for in customer engagement?

Twilio helps you build communication experiences that stay connected across channels using persistent conversation memory, real-time context, and AI-powered insights. You can send and receive messages, place voice calls, run video experiences, and build engagement flows that coordinate customer interactions across your stack.

Is Twilio more no-code or API-based for building workflows?

Twilio is primarily API-driven for communications and customer engagement, including messaging, voice, and video. For workflow building, Twilio also provides Studio, a visual workflow builder on Twilio’s serverless architecture.

Which communication channels does Twilio support?

Twilio supports multichannel messaging (SMS, RCS, WhatsApp, MMS, and more), voice calling, and video. For email, Twilio includes the Twilio SendGrid Email API, and you can also build email workflows alongside other channels with Twilio Email.

How does Twilio’s “conversation” layer work for AI agents and humans?

Twilio’s conversation products focus on persistent memory, orchestration, and intelligence. You can extract context from voice and messaging interactions using AI-powered transcription and analysis, keep a continuous conversation across channels and sessions, and relay voice AI into your communications stack to support scalable, human-like conversations.

What options do I have for routing and contact center workflows?

Twilio Flex can connect customers to the right virtual or live agent by orchestrating inbound and outbound interactions. For skills-based routing, TaskRouter helps route conversations based on controllable routing logic from your code.

Does Twilio offer onboarding support and security or compliance tools?

Twilio offers support and services with expert solution design, deployment assistance, and 24/7 support, along with support plans. For security and compliance, Twilio includes Interconnect for end-to-end, network-level security, Trust Hub for centralized onboarding for SHAKEN/STIR, CNAM, and phone number verification, plus a Twilio Privacy Portal to automate and scale data privacy and regulatory compliance tasks.
