Customer.io
Behavioral automation
Event-driven messaging platform built for product-led SaaS with strong segmentation, multi-channel journeys, and LLM workflow actions.
Zustellbarkeit
Customer.io supports custom sending domains with SPF and DKIM, plus separate workspaces for staging and production. Deliverability is generally solid for behavioral mail because sends are triggered and smaller in volume than broadcast blasts. Teams should still monitor bounces on event-triggered mail after schema changes.
Rendering
Liquid templating and a code editor give engineers control over HTML. Rendering quality depends on what you ship: simple transactional layouts render everywhere; heavy marketing modules need the same client QA as any custom build.
