About Twilio
Twilio is the leading cloud communications platform, providing APIs that let developers add voice, video, SMS, WhatsApp, email, and authentication capabilities to any application. Founded in 2008 in San Francisco by Jeff Lawson, Evan Cooke, and John Wolthuis, Twilio pioneered the 'communications as a service' model and went public in 2016. The platform powers communications for over 300,000 active accounts including companies like Airbnb, Lyft, DoorDash, and Salesforce. Twilio Messaging enables SMS and WhatsApp programmatically — for order confirmations, delivery updates, two-factor authentication, and marketing campaigns. Twilio Voice handles phone calls, IVR systems, and call center infrastructure. Twilio Verify provides phone number verification and 2FA. Twilio SendGrid (acquired 2019) handles transactional email and marketing email delivery at scale. Twilio Segment is a customer data platform for unifying customer data. Pricing is pay-per-use — SMS in the US is approximately $0.0079 per message sent/received. Voice calls are $0.013/minute. The platform's flexibility and reliability make it the default choice for developers building communications features, though its API-first nature requires technical implementation.

What is Twilio used for?
Twilio is used to send SMS notifications, build two-factor authentication, create phone verification systems, set up call centers, send WhatsApp messages, handle appointment reminders, deliver order updates, and manage transactional email (via SendGrid). It's the go-to API for any application that needs to communicate with users via phone or message.
Is Twilio hard to use?
Twilio requires technical implementation — it's an API platform designed for developers, not a no-code tool. However, Twilio's documentation is widely praised as industry-leading, with quickstarts in every major programming language (Python, Node.js, Java, Ruby, PHP, C#). Non-technical teams can use Twilio Studio (a visual flow builder) or tools like Zapier to trigger Twilio without code.
