How to calculate message deliverability rate
Why message deliverability rate matters for Customer.io users
Customer.io supports multi-channel messaging, and deliverability issues can affect each channel differently. An email deliverability problem may mask strong SMS performance, or vice versa. A unified deliverability metric ensures no channel-specific issue goes unnoticed.
Positioning deliverability rate as a foundational metric in your tree ensures that all downstream engagement and conversion metrics are interpreted in context. A conversion rate drop might not be a content problem - it might be a delivery problem that never surfaces in engagement-focused reporting.
