Lifecycle Funnel, Klaviyo

Lifecycle Funnel, stage by stage. The customer journey from subscriber to repeat purchaser, not the per-send engagement funnel. How to read it, why it matters, and how to act on it.

Metrics type: Supporting Metrics • Category: Email Marketing

The journey, not the send. This funnel tracks people moving from subscriber to first purchase to repeat purchaser, which is a different question from whether one email got opened.

At a glance

Lifecycle Funnel plots the customer journey through lifecycle stages, for example subscriber, engaged, first purchase, and repeat purchaser, stage by stage. It is deliberately DIFFERENT from the Engagement Funnel, which is a per-send mechanic: sent, delivered, opened, clicked. The engagement funnel asks “what happened to this email”; the lifecycle funnel asks “where is this customer in their relationship with the brand”. The drop-off between lifecycle stages tells you where customers stall: a wide subscriber-to-first-purchase gap is an activation problem, while a wide first-to-repeat gap is a retention problem. Stages are derived from profile and order history rather than from any single campaign.

What it counts	The count of customers at each lifecycle stage (for example subscriber, engaged, first purchase, repeat purchaser), shown as a descending funnel.
API endpoint + statistics field	Derived from profile state, engagement events and Placed Order history via GET /api/metrics and GET /api/metric-aggregates, bucketed into lifecycle stages.
Attribution model	A customer-state funnel, not a per-send attribution metric, so the 5-day click and 1-day view window does not gate stage membership.
Email vs SMS aggregation	Channel-agnostic. Stage membership reflects the customer’s overall relationship, not which channel reached them.
Chart type	Funnel (descending stages, one bar per stage).
Time window	Selected period (default 30 days) for stage transitions; some stages reflect cumulative profile state.
Alert trigger	A widening drop-off at any single stage transition versus the prior period, for example first-purchase to repeat shrinking.
Roles	owner, marketing

Calculation

Calculated automatically from your Klaviyo data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

An illustrative homeware brand on Shopify using Klaviyo. The 30-day window covers 14 Mar 26 to 12 Apr 26. Figures are illustrative and chosen to show stage shape.

Lifecycle stage	Customers	Stage-to-stage conversion
Subscriber (on list)	80,000	-
Engaged (opened or clicked recently)	28,000	35% of subscribers
First purchase	6,200	22% of engaged
Repeat purchaser	1,500	24% of first-time buyers

Subscriber -> engaged      = 28,000 / 80,000 = 35%
Engaged -> first purchase  = 6,200 / 28,000  = 22%
First purchase -> repeat   = 1,500 / 6,200   = 24%

What’s interesting:

1. This is not the engagement funnel. No sent, delivered, opened or clicked rows appear here. These are people at stages of a relationship, derived from profile and order history, not the fate of a single email. Keep the two funnels mentally separate.
2. The subscriber-to-engaged drop is the activation gap. Only 35 percent of subscribers are engaged. A large dormant base drags the whole funnel; a welcome flow and re-engagement programme widen the top.
3. Engaged-to-first-purchase at 22 percent is the conversion stage. This is where browse-abandonment and first-purchase incentive flows do their work. A weak number here is a content and offer problem, not a list problem.
4. First-to-repeat at 24 percent is the retention stage. This is the same loyalty signal that Repeat Purchasers counts as an absolute number. A narrow transition here is the most expensive leak, because re-earning a lost first-time buyer costs more than nurturing them.
5. Find the narrowest transition and fix that. Effort spent widening an already-healthy stage returns little. The lifecycle funnel exists to point you at the single stage where customers stall.

Sibling cards merchants should reference together

Read these alongside Lifecycle Funnel to understand each stage and to keep it distinct from the per-send funnel.

Card	Why pair it with Lifecycle Funnel
Engagement Funnel	The per-send funnel (sent, delivered, opened, clicked). Read it to avoid confusing email mechanics with customer lifecycle.
Active Subscribers	Sizes the top of this funnel, the subscriber and engaged stages.
Predicted CLV Tiers	Adds a value dimension: which lifecycle stages hold the high-CLV customers.
Repeat Purchasers	The absolute count behind this funnel’s deepest stage.
Top Segments by Revenue Send	Surfaces which segments map to each stage so you can target the narrowest transition.

Reconciling against Klaviyo

Where to look in Klaviyo:

Klaviyo does not ship a single lifecycle funnel chart, so this card composes it from segment counts. Build segments under Audience → Lists & Segments for each stage (all subscribers, engaged in last 30 days, has placed one order, has placed two or more orders) and read each profile count. Klaviyo’s Analytics → Customers and any RFM dashboards offer adjacent cohort views.

Why our number may legitimately differ:

Reason	Direction of divergence
Stage-definition choices. “Engaged” and “repeat” depend on thresholds (engagement recency, order count). A segment built with different rules counts differently.	Direct function of the definitions used
Time zone. Klaviyo evaluates dates in the account time zone; Vortex IQ defaults to UTC. Boundary transitions can shift.	Small count difference at the window edge
Cumulative vs windowed stages. Some stages reflect cumulative profile state and some reflect transitions in the window. Mixing the two when comparing to Klaviyo segments causes apparent gaps.	Either direction, definition-dependent
Profile merging. Duplicate profiles not yet merged can place one customer in two stages until Klaviyo reconciles them.	Either direction until profiles merge
Event coverage. Stage membership depends on engagement and order events reaching Klaviyo. Integration gaps undercount the lower stages.	Lower stages can understate

Known limitations / merchant FAQs

How is this different from the Engagement Funnel? The Engagement Funnel tracks one send through sent, delivered, opened and clicked. The Lifecycle Funnel tracks a customer through subscriber, engaged, first purchase and repeat purchaser. One is about email mechanics; the other is about the customer relationship. They answer different questions.

Why doesn’t the top of the funnel match my open or click rate? Because this funnel is not built from a single send. The “engaged” stage reflects recent engagement across all activity, not the opens or clicks on one email. For per-send rates use the engagement funnel.

The stage definitions seem arbitrary. Can I change them? The thresholds for “engaged” and “repeat” are configurable through the segments that feed each stage. If you change a definition, rebuild the matching Klaviyo segment with the same rule before comparing counts.

My subscriber-to-engaged drop is huge. Is that bad? A large dormant base is common, especially after aggressive list acquisition. The fix is a strong welcome flow plus a re-engagement programme to widen the engaged stage. It is an activation problem, not necessarily a list-quality problem.

Where does this overlap with Repeat Purchasers? The funnel’s deepest stage is the same population Repeat Purchasers counts. This card shows it as the end of a journey; that card shows it as a single number.

Does channel affect which stage a customer sits in? No. Stage membership is channel-agnostic and reflects the customer’s overall behaviour, whether reached by email, SMS or neither.
