Customer.io is a powerful messaging automation platform designed for tech-savvy product and marketing teams who need to send targeted, behavior-based messages across email, SMS, push notifications, and in-app channels. Founded in 2012, Customer.io serves thousands of SaaS companies, mobile apps, and e-commerce businesses that need sophisticated triggered messaging based on user actions and attributes. The platform is particularly popular among developers and growth teams for its flexible API, robust data model, and ability to trigger messages based on real-time events.

Customer.io pricing starts at $100/month for the Essentials plan (5,000 profiles) and scales to $1,000+/month for Premium and custom Enterprise pricing. Unlike traditional email marketing tools that price by contacts alone, Customer.io uses a profile-based model that includes both people and objects (companies, products, orders), giving you more flexibility to track relationships and trigger complex workflows. The platform stands out for its unlimited email sends, multi-channel capabilities, and developer-friendly infrastructure.

In this pricing guide, we break down what each Customer.io tier includes, how profile-based pricing works, the additional costs for SMS and push notifications, overage charges when you exceed profile limits, and the hidden costs around object types, data retention, and premium support that impact your total spend.
