Form Conversion Rate

List growth rate measures the net rate at which your Klaviyo subscriber list expands over a given period, accounting for new subscriptions, unsubscribes, bounces, and manual removals. It indicates the trajectory of your addressable email audience and the sustainability of your acquisition efforts.

Email engagement cohort analysis groups Klaviyo subscribers by their signup date or acquisition source and tracks how their engagement evolves over time. It reveals whether newer cohorts engage as well as older ones and how quickly engagement decays after initial subscription.

Email list health score is a composite metric combining Klaviyo list growth rate, engagement distribution, bounce rate, complaint rate, and unsubscribe rate to produce a single indicator of overall list quality. It assesses whether your subscriber base is growing, engaged, and deliverable.

Profile enrichment rate measures the percentage of Klaviyo subscriber profiles that have key data fields populated beyond the basic email address - such as name, preferences, purchase history, location, and behavioural attributes. It indicates how much personalisation data is available for targeting and content customisation.

Unsubscribe rate measures the percentage of Klaviyo email recipients who opt out of future communications after receiving a message. It serves as a direct indicator of message relevance, frequency appropriateness, and the overall health of the relationship between your brand and its subscribers.
