Ecommerce email & retention playbook (Klaviyo, UK, 2026)
The Klaviyo playbook for UK DTC brands - flows, segmentation, campaigns, SMS, GDPR and the retention metrics that build repeatable revenue.
Short answer first
Email should drive 20-35% of revenue for a UK DTC brand. That comes from six flows (welcome, browse-abandon, cart-abandon, post-purchase, winback, birthday) plus a weekly campaign cadence, all built on segmentation.
Why Klaviyo for UK Shopify
Native Shopify integration, event-level segmentation, revenue attribution baked in. Above £30K/month, Klaviyo pays back in weeks over Mailchimp or Omnisend.
The six core flows
- Welcome flow - 5 emails, 10-14 days. 8-14% first-purchase conversion.
- Browse abandonment - 2 emails, 24 hours.
- Abandoned cart - 3 emails over 48h. 15%+ recovery.
- Post-purchase - 45-180 days depending on category.
- Winback - triggered at 2x average repurchase window.
- Birthday - one email with a small gift or discount.
Together these should drive 65-80% of email revenue.
Segmentation
- Engaged 30 (opened/clicked in last 30 days) - your money segment.
- Engaged 90 - broader nurture.
- Non-engaged 120+ - sunset or winback only.
- VIP (top 10% LTV) - separate cadence, softer offers.
- Recent purchasers - suppress from acquisition campaigns.
Campaign cadence
2-3 campaigns/week to engaged segments, 1-2 to broader lists. Rotate: product education, launch, curated collection, story, offer. Never more than 25% offer-led or you erode margin.
SMS layer
Add SMS to abandoned cart, shipping updates, back-in-stock and time-sensitive campaigns only. Full details in SMS + email: the UK compliance-safe combo.
Metrics that matter
- Email revenue as % of total (target 20-35%).
- Flow revenue vs campaign revenue (65/35 healthy).
- List growth rate (5-12%/month).
- Engaged 30 as % of list (target 25-40%).
- Placed order rate per campaign (0.4-0.8% for cold-ish sends, 1.5%+ for engaged).

Healthy target: 20-35% of total revenue. Below 15% you're under-investing in retention; above 45% you're likely dependent on discounting or single-buyer cohorts.
