At a glance

Customers in the database whose lifetime spend is £0 (have an account but no purchase). The dormant-account count; reveals signup-without-conversion friction or stale list inflation.

Calculation

Calculated automatically from your Shopify 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 activewear DTC brand on Shopify, ~32,000 customer base. Snapshot 12 May 26. The card reads 33.1%, 13.1 ppt above the 20% threshold. Six things to notice:
  1. The alert is firing. 33% zero-spend is well above healthy norms. For a DTC apparel brand, target 10-25% zero-spend (room-for-acquisition without bloating list).
  2. The cohort is recoverable. 10,600 customers have an account but never bought; they signed up because of email-discount, contest entry, account-creation prompt, or download-gate. Most are recoverable with a welcome flow that converts to first purchase.
  3. Marketing-spend trap. If you pay Klaviyo or another email tool per active profile, 10k zero-spenders are dead weight. List-pruning saves cost and improves deliverability metrics.
  4. Recovery campaign opportunity. A reactivation campaign (welcome-discount + showcase products + social proof) targeting zero-spenders typically converts 2-5%. 10,600 customers × 3% = 318 incremental customers from a single campaign.
  5. Imported customer artifact. If you migrated from Mailchimp or another platform recently, many zero-spenders may be email-only subscribers, not Shopify customers in the conversion sense. Consider whether they should be tagged differently.
  6. The “zero spend” definition matters. A customer who bought £100 and refunded £100 shows as zero spend. Pair with order-history to differentiate “never bought” from “bought and fully refunded”.

Reconciling against the vendor’s own dashboard

Where to look in Shopify Admin:
Shopify Admin → Customers filtered by Number of orders is 0 OR Total spent is 0
The most direct equivalent. Sum the matching count and divide by total customer count. Other Shopify Admin views:
  • Customer segments: build a segment for “no purchases yet” customers.
  • Apps like Klaviyo, Hubspot, Reactivate: their dashboards expose dormant cohorts and reactivation tools.

Known limitations / merchant FAQs

Why is my zero-spend rate so high? Three usual causes:
  1. Email-capture popup-driven signups: customers signed up for the WELCOME10 code, never converted. Common; 60-80% of popup signups never buy.
  2. Account-creation gating: requiring account creation to access certain pages or features creates accounts without purchase intent.
  3. Email-list import: customers imported from Mailchimp / Klaviyo / past CRM with no purchase history.
What’s a healthy zero-spend rate? Category-dependent rough guides:
  • Acquisition-heavy DTC: 25-40%. Heavy popup-driven signups. The reactivation challenge is real.
  • Subscription brands: 5-15%. Customers usually buy on first visit (subscription is the buy).
  • Marketplace-cross-listed brands: 30-50%. Many email-only signups for offers.
  • Hybrid retail with POS email-capture: 30-45%. In-store email captures often don’t convert online.
Should I purge zero-spenders? Not aggressively. The right approach:
  1. Try reactivation campaign first: target with a strong offer (e.g. 25% off first order, free gift with purchase). Conversion typically 2-5%.
  2. Wait 6-12 months: if no conversion after multiple campaigns, the customer is unlikely to buy.
  3. Tier-based pruning: keep recent zero-spenders (<6 months); prune old (>12 months) without engagement.
Does this card include POS walk-ins without email? No. POS customers without email-capture aren’t created as Shopify customer records, so they don’t appear in either numerator or denominator. The card measures the email-captured customer base only. Why does this matter for marketing-tool costs? Klaviyo, Mailchimp, and similar tools price based on active profile count. 10,000 zero-spenders sitting on the list cost the same as 10,000 paying customers but generate no revenue. Pruning improves cost-per-active-customer. Action playbook for zero-spenders:
  1. Welcome-flow review: confirm the welcome flow (1-3 emails) is firing for all signups. Optimise the discount code, social proof, hero products.
  2. Reactivation campaign: target zero-spenders aged 30-180 days with a stronger offer.
  3. Pruning policy: define when to prune (e.g. >12 months no purchase + no email engagement); execute quarterly.
  4. Signup-source tagging: use Shopify customer tags to identify popup vs other sources; lifetime conversion may differ by source.
  5. Cost monitoring: track per-active-customer marketing tool spend; rising zero-spend share inflates this.
  6. Conversion measurement: post-reactivation campaign, watch how many zero-spenders converted; refine offer based on results.
