Ivana Kostic | Klaviyo Email & SMS Lifecycle (Global eCom)

Klaviyo Email & SMS systems designed to drive predictable eCommerce revenue.

I don’t just improve email performance — I build systems that scale safely.

eCommerce brands work with me to turn Klaviyo into a predictable revenue system — not just “sending campaigns,” but building a lifecycle engine that improves conversion, increases repeat purchases, and keeps deliverability healthy long-term.

With 9+ years of experience, 155+ completed projects, and Klaviyo Silver Master Partner status, I bring a strong technical foundation across Shopify, WordPress, and WooCommerce ecosystems. Brands across multiple industries rely on this approach for end-to-end growth execution: store optimization, integrations (including custom setups), analytics foundations, customer journey strategy, and lifecycle automation — so email and SMS work as part of a complete funnel, not in isolation.

What I do best (and what clients hire me for):

• Klaviyo setup, audits, and account cleanup
• (integrations, custom integrations, account structure, lists, segmentation, tracking/events, deliverability foundations, and troubleshooting across common platform issues)
• High-performing flows built around real customer behavior:
• Welcome, Browse Abandonment, Cart & Checkout Abandonment, Post-Purchase (split by order count), Repeat Purchase, Winback, Back in Stock, Review Request, and Sunset/Unengaged flows
• Segmentation based on intent and value
• (VIP & LTV tiers, engagement windows, product/collection interest, category affinity, purchase readiness)
• Campaign strategy and execution
• (monthly planning, offer structure, QA/testing, performance reporting, and ongoing optimization)

Because I understand the full funnel, I can also support the pieces that usually block performance: Shopify/WooCommerce issues, custom integrations, tracking clarity, on-site conversion gaps, and the marketing foundations that make automation profitable (product positioning, storytelling, and offer logic).

My approach is practical and process-driven — I focus on measurable improvements, not theoretical analysis.

Best fit:

Shopify and DTC eCommerce teams that want a senior partner who can own strategy, build, and optimization — and deliver consistent, measurable growth without chaos.
