Customer.io

Data-driven messaging automation for product-led companies

Overview

Customer.io is a messaging-automation platform used mainly by software and app companies to send behaviour-triggered e-mail, push and in-app messages based on product data. It reports more than 11,000 brands using the platform.[12]

Unlike many tools, Customer.io publishes a full price ladder in US dollars. Essentials starts at US$100 a month for 5,000 profiles and one million e-mails, rising to US$145 for 10,000 profiles, US$235 for 20,000, US$325 for 30,000, US$415 for 40,000 and from US$505 for 50,000, with extra profiles at US$0.009 each and extra e-mails at US$0.12 per thousand.[12] Essentials includes the visual workflow builder and two object types for modelling accounts or other entities.[12] Premium, from US$1,000 a month billed yearly, adds ten object types, higher AI-agent limits, a native Salesforce integration and 90-day onboarding, with HIPAA compliance as an add-on; Enterprise adds dedicated infrastructure and audit logging.[12]

Data can be stored in US or EU data centres at no extra charge, and web push is free on every plan.[12] Companies that have raised under US$10 million can receive a year free through its start-up programme.[12] Customer.io assumes access to product event data and technical set-up, making it less suitable for marketers without developer support.
