About Customer.io
Customer.io is widening what a journey can express and where its agent can be reached.
Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.
