Sales Klaviyo

• You are building or troubleshooting Klaviyo Flows (abandoned cart, welcome series, winback, post-purchase) and need platform-specific steps
• Your Shopify-Klaviyo integration is broken, events are missing, or the OAuth connection shows "Action Required"
• You want to set up SMS in Klaviyo including 10DLC registration, consent collection, and cross-channel flow design
• You need to use the Klaviyo REST API to sync profiles, track events, or handle rate limits programmatically
• Predictive attributes (CLV, churn risk) are missing or your segments are returning unexpected contacts

• You need general email marketing strategy not tied to Klaviyo — use /sales-email-marketing instead
• You are troubleshooting cross-platform email deliverability (SPF/DKIM/DMARC, inbox placement) — use /sales-deliverability
• You are working with a competing platform like Customer.io or Mailchimp — use /sales-customerio or /sales-mailchimp

Step-by-step guidance for building abandoned cart, welcome, winback, post-purchase, and browse abandonment flows. Includes cross-channel SMS fallback design, conditional split logic, and per-step conversion monitoring.

Help constructing real-time segments using behavioral conditions combined with Klaviyo's predictive attributes — predicted CLV, churn risk, next order date, and spend tier. Includes data threshold guidance for when predictions become available.

Diagnose and fix Shopify-Klaviyo sync issues including missing events, broken OAuth connections, duplicate script loading causing form failures, and coupon sync configuration.

End-to-end guidance for SMS in Klaviyo: 10DLC brand registration, toll-free/short code setup, consent collection via multi-step forms, quiet hours configuration, and cross-channel flow design that respects SMS consent.

Practical help with the Klaviyo REST API — profile upserts, event tracking, scope configuration, JSON:API request formatting, rate limit handling with exponential backoff, and cursor-based pagination.

Documented fixes for common Klaviyo issues: predictive scores not appearing, flow emails sending to already-converted customers, SMS stuck in queue, popups not triggering in Chrome, and Shopify integration reconnection failures.

Build a multi-touch abandoned cart flow triggered by Shopify's "Checkout Started" event, with dynamic product blocks, unique coupon codes, and an SMS fallback for subscribers who haven't opened the email.

Create a segment targeting high-CLV customers with medium-to-high churn risk, then trigger an automated winback flow with personalized product recommendations and a loyalty incentive before they lapse.

Design a multi-step signup form that collects email first then SMS consent, followed by a personalized onboarding email sequence that drives first purchase conversion.

Diagnose broken Shopify integrations, missing Klaviyo events, or API errors — including OAuth reconnection failures, duplicate script issues causing form problems, and profile sync troubleshooting.
