What is Customer.io?
Customer.io is a messaging and marketing automation platform that lets businesses send highly targeted, behavior-driven communications — email, push notifications, SMS, and more — based on what users actually do. Generic, one-size-fits-all messaging performs poorly; the most effective communication is triggered by user behavior and tailored to each person's journey. Customer.io is built around exactly this, using real-time data about user actions to send the right message to the right person at the right moment, enabling sophisticated, automated lifecycle and engagement messaging that drives real results.
The platform ingests data about user behavior and attributes, then lets teams build automated workflows that send messages based on what users do, who they are, and where they are in their journey — welcome sequences, onboarding nudges, re-engagement campaigns, behavioral triggers, and more. It supports multiple channels (email, push, SMS, in-app) so messages reach people where they are, and provides segmentation, personalization, and testing to make communications relevant and effective. Designed for teams that want powerful, data-driven control over their messaging rather than basic blast emails, it's especially popular with product-led and technical companies that have rich behavioral data to act on.
Customer.io is used by businesses — particularly product-led, SaaS, and tech companies — that want to send sophisticated, behavior-driven messaging to engage, onboard, and retain users. The value is relevant, automated communication at scale: by triggering messages on real user behavior across multiple channels, it makes engagement far more effective than generic campaigns, improving onboarding, retention, and conversion. Because relevant, well-timed messaging meaningfully affects how users adopt and stick with a product, this capability is valuable. For teams that have behavioral data and want to use it to communicate intelligently and automatically with their users, Customer.io offers a powerful, flexible platform built for exactly that.

Connect a Facebook Page and its linked professional Instagram account, choose the posts to monitor, and create reply rules triggered by keywords or hashtags.
