Healthy DTC sits 20-40% email-attributed. Below = leaving money on the table; above = list dependency risk if deliverability tanks.

At a glance

The share of WooCommerce store revenue attributed to email (Klaviyo, Mailchimp, Dotdigital). Healthy DTC sits 20-40%. Below means leaving money on the table; above means list-dependency risk if deliverability tanks.

Calculation

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

Worked example

A US homewares brand on managed-Woo, Klaviyo for email. 30D window: 14 Mar 26 to 12 Apr 26. Three observations:
  1. 24.1% is healthy DTC territory. The brand sits comfortably in the 20-40% band. Common pattern: 60% of the email revenue comes from automated flows (welcome, abandoned cart, post-purchase); 40% from broadcast campaigns. Klaviyo’s “Flows vs Campaigns” tab provides the split.
  2. Self-hosted variance is the recurring theme. This brand previously ran on shared hosting with intermittent sync delays; the email-attribution alignment between Klaviyo (real-time webhooks) and Woo (hourly poll) drifted by 15-30 min, causing daily email-share figures to swing by 1-3 ppt. Pressable’s reliable sync brought daily figures within 0.5 ppt accuracy.
  3. Plugin-induced data shape variance: Klaviyo for WooCommerce. The plugin sets cookies tracking email source on the customer; Woo orders inherit the source via custom meta _klaviyo_attributed_to. If a merchant runs a coupon discount that auto-applies via Klaviyo, the same order can show up under both “email” and “discount” attribution. Klaviyo’s last-click model resolves the conflict; cross-checks against Woo coupon usage may show small overlap.

Known limitations / merchant FAQs

Self-hosted vs managed-Woo, why does it affect attribution? Webhook delays on self-hosted Woo can briefly mis-time the email-attributed order so it falls outside the ESP click window. Managed-Woo with reliable webhooks rarely shows this. Status-filter selection, why use completed + processing for the denominator? This is the canonical Woo “real revenue” definition. Including pending or on-hold would dilute the email-share with not-yet-paid revenue. Refund-object accounting, does it affect the share? Both numerator and denominator are gross of refunds. The ratio is consistent. To see the post-refund share, use net revenue on both sides. Plugin-induced data shape variance, what plugins matter?
  • Klaviyo for WooCommerce: real-time webhook, 5-day default attribution.
  • Mailchimp for WooCommerce: hourly sync, 7-day default attribution.
  • Dotdigital for WooCommerce: hourly sync, 14-day default attribution.
  • Sendinblue / Brevo: real-time webhook, configurable attribution window.
Multi-currency configuration, how do I ensure accuracy? Both ESP and Woo must report in the same currency for the ratio to be meaningful. Most ESPs report in store base currency; if your store sells in mixed currencies, filter both views to a single currency. Why does Woo and Klaviyo disagree on email revenue? Different attribution windows, different click vs open vs view definitions, and Woo refunds occasionally update post-attribution. A 5-15% disagreement is normal. ESPs are the source of truth for email-attributed revenue; Woo is the source for total revenue. Why does email share drop on heavy POS weeks? POS orders rarely have ESP attribution (no email-sourced click). They inflate the denominator without inflating the numerator, dropping the share. Use a web-only filter for the cleaner view. Today is jumpy, why? Email attribution windows can take 5-14 days to fully resolve. Today’s email share is incomplete; use 30D rolling. Sync-lag from self-hosted server slowness? Webhook delays produce minor mis-timing. Self-resolves at next ESP webhook retry. My ESP shows different numbers, debug:
  1. Match the date window exactly.
  2. Match the attribution window setting (5-day vs 7-day vs 14-day).
  3. Confirm currency alignment.
  4. Acknowledge that ESP attribution and Woo revenue have different update cadences.
