Why email deliverability analysis matters for Customer.io users
No engagement metric matters if your emails do not reach the inbox. Deliverability issues silently undermine every campaign, workflow, and broadcast in Customer.io. A gradual decline in deliverability can erode your entire messaging programme before it shows up in open rates.
Positioning deliverability analysis at the foundation of your metric tree ensures technical email health is monitored before engagement metrics. When deliverability drops, your tree shows the cascading impact on opens, clicks, conversions, and revenue.

Marketing AutomationMetric Definition
Deliverability Rate = (Messages Delivered / Messages Sent) x 100

Email Open Rate
Marketing AutomationMetric Definition
Open Rate = (Unique Opens / Emails Delivered) x 100

While affected by privacy features like Apple Mail Privacy Protection, it remains a useful directional indicator of subject line effectiveness and sender reputation when tracked consistently over time.
Email Unsubscribe Rate
Marketing AutomationMetric Definition
Unsubscribe Rate = (Unsubscribes / Emails Delivered) x 100

Transactional Message Success Rate
Marketing AutomationMetric Definition
Transactional Success Rate = (Successfully Delivered Transactional Messages / Transactional Messages Triggered) x 100
Transactional message success rate measures the percentage of Customer.io transactional messages - such as password resets, order confirmations, and account notifications - that are successfully delivered and rendered. Unlike marketing messages, transactional messages are critical to user experience and product functionality.
