Klaviyo + Postscript SMS for cart abandonment + winback, what do you set up?

For supplements DTC, Klaviyo + Postscript is the email/SMS stack, combined they typically drive 30-40% of revenue at well-optimized brands. Magento integration via the official Klaviyo extension + Postscript’s API + Klaviyo data sync.

The flow inventory I build for every supplements brand:

• Welcome series, 5 emails over 14 days. Day 0 (capture + 10% off), day 1 (founder story / brand mission), day 3 (top-seller social proof), day 7 (quiz funnel push), day 14 (last-chance discount). Pulls 8-15% revenue.
• Abandoned cart, 3 emails (1h, 24h, 72h) + 1 SMS at 4h via Postscript. SMS converts 2-3x email. Always include the cart items + a soft discount on email 3.
• Abandoned quiz, underrated. Customer started quiz, gave email, dropped off. 2-email flow recovering 15-25% of drop-offs.
• Post-purchase nurture, day 3 (how to use), day 14 (community / Instagram tag), day 25 (review request via Yotpo / Okendo), day 45 (refill reminder if not subscribed).
• Subscription pre-billing reminder, 3 days before renewal. “Your collagen ships Tuesday, want to swap, skip, or add something?” Cuts surprise-cancel churn 18-25%.
• Win-back, cancelled-sub flow at day 30, day 60, day 90 post-cancel. Soft discount escalator (10%, 15%, 20%).
• Replenishment, for non-subscribers. Based on SKU consumption rate (30-day supply → reminder at day 25). Drives 12-18% of repeat revenue.
• Browse abandonment, viewed PDP, didn’t add. Lighter touch than cart abandonment, 1 email + segmented by category.

Postscript SMS specifically: keyword-driven opt-in on PDP (“Text JOIN to 12345”) gets 5-15% of site visitors. SMS list grows slower than email but converts 2-3x higher. Use for cart abandonment, subscription reminders, restock alerts, and product launches, not for daily promotional blasts.
