What is Twilio?

Twilio is a cloud communications platform that gives developers APIs to add messaging, voice calling, video, email, and authentication features to their applications. Core products include Programmable SMS and MMS, Voice, Video, WhatsApp and RCS messaging, the SendGrid Email API, and Verify for two-factor authentication, alongside Flex for building contact centers and Segment for customer data management. Companies including Uber, Airbnb, Netflix, and HubSpot use Twilio to power customer communications.

Pricing is usage-based rather than flat subscription tiers: SMS costs around $0.0083 per message, voice starts near $0.0085 per minute to receive, and phone numbers start around $1.15 per month, with volume discounts at scale. SendGrid Email offers a free plan for up to 100 emails per day, and Twilio provides a free trial with no credit card required for new developers to test the platform.
