Customer.io is a proprietary SaaS platform for lifecycle marketing, customer messaging, and event-driven automation. It helps teams send targeted email, SMS, push, and in-app messages based on user behavior and segmentation. It is especially useful for product-led companies, SaaS teams, and subscription businesses.
Customer.io is a proprietary subscription service priced mainly by active people rather than seat count. Plans typically include Standard, Plus, and Advanced tiers, with Standard starting around $60/month for up to 5,000 active people, Plus starting around $150/month, and Advanced starting around $1,000/month for larger accounts. Pricing scales as contact volume increases, and annual billing can reduce costs, while a free trial is usually available for evaluation.
