About Twilio
Twilio is a communications platform for developers. Its core APIs cover messaging (SMS, WhatsApp, and RCS), voice and SIP trunking, email (including an SMTP service), and phone number provisioning — local numbers, toll-free numbers, 10DLC, and short codes. There is also a Video API and Flex, a programmable contact center. For authentication, Twilio offers Verify (one-time passcodes) and Lookup (phone number intelligence). The customer data side, built on Segment, includes Connections, Warehouses, Unify, Engage, Audiences, and Journeys for collecting and activating customer profiles. Newer products sit under a Conversational AI umbrella: Conversation Relay for building voice AI agents, Conversation Intelligence for extracting context from real-time conversations, Conversation Memory for persistent customer context, and Conversation Orchestrator for keeping conversations connected across channels. Use cases listed on the site include user verification, fraud prevention, alerts and notifications, appointment reminders, mass texting, SMS marketing, IVR, and contact centers. Twilio targets industries from financial services and healthcare to retail, ecommerce, and the public sector, and positions itself for both startups and enterprises. The site is available in English, French, German, Japanese, Portuguese, and Spanish. Support options include a help center, paid support plans, and partner solutions.
