Klaviyo on Shopify: activating Email & SMS as a retention lever from launch
Last updated: January 12, 2026
Reviewed by Marion: Shopify Expert at LobsTTer
Klaviyo is the most in-demand Email & SMS CRM tool on Shopify. In practice, the question isn't "should I install Klaviyo?", but how to properly activate it: reliable tracking, consents, deliverability, segmentation, profitable flows, then data-driven iterations. This is exactly what we do at LobsTTer: an operational CRM foundation from the start, followed by continuous optimization aligned with your objectives (repurchase, average order value, LTV, margin).
◎ For whom is Klaviyo a priority?
- Priority if you have a recurring catalog (fashion, beauty, home), established traffic, or if you are preparing a Shopify redesign or migration.
- Priority if you have seasonal peaks: welcome and post-purchase flows structure the ramp-up without multiplying manual campaigns.
◎ What "connecting Klaviyo" means in practice
- Clean Shopify events: product view, add to cart, checkout, purchase, refunds, ID consistency.
- Consents & compliance: explicit SMS collection, controlled marketing pressure, GDPR foundation.
- Deliverability: sending domain, SPF, DKIM, DMARC, tests, warming if necessary.
- Useful segmentation: truly actionable segments (new customers, VIPs, dormant, recent buyers).
- Profitable flows: priority to automations that generate revenue.
◎ The Klaviyo flows that generate revenue
- Welcome Series: activation and first conversion.
- Abandoned Cart: direct revenue recovery.
- Abandoned Browse: intentional re-engagement.
- Post-Purchase: satisfaction, cross-sell, replenishment, reduced support.
- Winback: re-activation of dormant customers.
- VIP / Engaged Customers: increased value and loyalty.
