Klaviyo Marketing Specialist Contractor
· Remote in Latin America only
· Full-time
· US Eastern Time Zone English level: Advanced / fluent (daily written and spoken communication with US stakeholders) About the client Our client is a fast-growing, US-based direct-to-consumer (DTC) brand in the health and fitness supplements space. They sell through their own Shopify store, largely on a subscription model, and run a high-volume, performance-driven marketing engine where email and SMS are core revenue channels.

About the role
We are looking for a Klaviyo specialist who can own the client's email and SMS program end to end: strategy, execution, and results. You will turn a large, engaged customer base into predictable revenue through smart segmentation, well-built automated flows, and a disciplined campaign calendar. You will work closely with a copywriter and a designer, and you will be the person who decides what gets sent, to whom, and why. Responsibilities
• Own the Klaviyo account day to day: campaign planning, building, scheduling, QA, and sending.
• Build, audit, and optimize core lifecycle flows: welcome, browse and cart abandonment, post-purchase, replenishment, winback, and subscription retention / cancellation save.
• Design and maintain a segmentation strategy based on purchase behavior, subscription status, engagement, and customer value.
• Run a structured A/B testing roadmap (subject lines, offers, timing, layout, flow logic) and turn results into clear next steps.
• Protect deliverability: domain authentication, list hygiene, sunset policies, engagement-based sending, and inbox placement monitoring.
• Plan and execute promotional calendars for sales, product launches, and seasonal pushes, in coordination with the wider marketing team.
• Manage SMS campaigns and flows alongside email, keeping frequency and messaging consistent across channels.
• Brief and direct the copywriter and designer, and review their work before anything goes live.
• Keep Klaviyo integrations healthy (Shopify, subscription, reviews, and returns apps) and flag data or tracking issues early.
• Report weekly and monthly on revenue attribution, flow vs. campaign performance, revenue per recipient, list growth, and churn signals, with recommendations, not just numbers. What you bring
• 4+ years in email / lifecycle marketing, with most of that time in ecommerce or DTC brands.
• 3+ years of hands-on Klaviyo experience, including building complex flows, conditional splits, and dynamic segments.
• A track record of measurable revenue impact from email and SMS, and the ability to explain what drove it.
• Solid understanding of deliverability best practices and how to recover a struggling sender reputation.
• Experience with Shopify-based stores and subscription business models.
• Comfortable with data: you can read Klaviyo and Shopify reports, build simple analyses in spreadsheets, and spot anomalies quickly.
• Strong project management and the confidence to push back on stakeholders when a send does not make sense.
• Advanced English, written and spoken. Nice to have
• Klaviyo certifications.
• Experience with SMS platforms (Klaviyo SMS, Postscript, Attentive).
• Background in health, wellness, supplements, or other high-volume DTC categories.
• Basic HTML/CSS for email troubleshooting.
• Agency experience managing several Klaviyo accounts at once. Why join us?
• Competitive compensation paid in USD.
• 100% Remote.
• Paid Time Off: 12 PTO days per year.
• Local Holidays: All official holidays in your country.
• Birthday Off.
• Career Growth opportunities.
• Recognition Program.
