Twilio Segment

Twilio Segment is a customer data platform that collects events once and routes them to 700+ destinations and a warehouse, with a free tier and a Team plan.

Twilio Segment is the customer data platform that started as a way to instrument a website once and send the events everywhere, for engineering and analytics teams that want one pipeline feeding many tools and a warehouse. Twilio, the San Francisco communications company, owns Segment after acquiring it, and the product's pricing and documentation now live on twilio.com. Connections is the core: web, mobile, server and cloud app sources, an HTTP tracking API, more than 700 destination integrations, a data warehouse destination, reverse ETL that reads warehouse tables back into tools, and Functions for writing a custom source or destination in a few lines of code. Events stream in real time, a source event delivery dashboard shows what each source received and what failed, and a public API automates the account. On top sit the parts that make it a full customer data platform: Unify for identity resolution, unified customer profiles and the Profile API; Engage for audiences, computed traits and journeys; Protocols for tracking plan enforcement; Consent Management with GDPR and CCPA deletion and suppression; Data Graph and Linked Audiences for warehouse-native audiences; Replay for backfilling a new tool from archived data; regional hosting in the US or the EU; single sign-on and granular roles; HIPAA eligibility with a BAA; and AI predictions and recommendations add-ons. Twilio Segment suits engineering teams instrumenting events once for many tools, product and analytics teams feeding a warehouse, marketing teams buying the full customer data platform for audiences and journeys, companies that need EU data residency for customer events, and startups starting on the free tier with a couple of sources. Connections is sold on a permanent Free tier and a Team plan priced by monthly tracked users, billed monthly with an annual discount and a trial, and the Business tier and the Connections, Unify and Engage bundle are quoted by sales, which is where identity resolution, audiences, Protocols, consent enforcement, regional hosting and single sign-on live. A working Segment account collects first-party events and fans them out to analytics and ad tools, syncs warehouse tables back into marketing tools with reverse ETL, merges anonymous and known activity into one profile, builds audiences from behaviour and computed traits, enforces a tracking plan before bad events reach destinations, routes events only to the destinations a user consented to and replays archived data into a newly added tool. It sits beside the warehouse and every tool it feeds rather than replacing them.
