As our Email/SMS Implementer, you'll be the production engine behind our retention program. You'll take approved copy and design and turn them into accurate, responsive campaigns and lifecycle flows in Klaviyo and Postscript. You'll own build quality, links, segmentation, scheduling, QA, and the final checks that make sure the right customer receives the right message at the right time.

You'll work inside a small in-house retention pod alongside a copywriter and designer, with clear ownership of execution and a high bar for speed and detail.

What You'll Do:

• Build email campaigns and lifecycle flows in Klaviyo from approved copy and Figma designs
• Build and schedule SMS/MMS campaigns in Postscript, including links, media, segmentation, and send settings
• Maintain reusable templates and modular content blocks so recurring campaigns can be produced quickly without sacrificing quality
• Set up segments, flow triggers, filters, delays, splits, suppression logic, and dynamic content based on the campaign or flow brief
• QA every send before launch, including copy accuracy, links, UTMs, discount codes, personalization, images, mobile rendering, dark mode, and footer/compliance requirements
• Test emails across major clients and devices, including Gmail, Apple Mail, and Outlook, and flag rendering issues before launch
• Implement A/B tests accurately and confirm the test setup matches the stated hypothesis
• Schedule campaigns and publish flow updates only after final approval from the retention team
• Troubleshoot broken links, incorrect logic, rendering issues, and other production errors quickly when they occur
• Keep Klaviyo and Postscript organized, including naming conventions, archived versions, templates, and documentation
• Partner with the Copywriter and Designer to flag anything in a brief that cannot be implemented cleanly before it becomes a last-minute production issue

Must-Have Requirements:

• 2+ years of hands-on email production or lifecycle marketing implementation experience for a DTC, ecommerce, or agency environment
• Strong hands-on experience building campaigns and flows in Klaviyo
• Experience with an SMS platform such as Postscript, Attentive, or similar
• Comfortable working from Figma files and copy documents and translating them precisely into production-ready sends
• Strong understanding of segmentation, flow logic, personalization, suppression, scheduling, and basic deliverability hygiene
• Strong QA discipline and exceptional attention to detail, especially around links, offer logic, customer eligibility, and send settings
• Working knowledge of responsive email behavior, mobile rendering, dark mode, and common Gmail/Apple Mail/Outlook constraints
• Ability to work quickly across multiple campaigns and flows while meeting deadlines in a remote environment
• Clear written English and the ability to communicate production risks or questions early
• Self-starter who takes ownership, follows documented processes, and is comfortable being accountable for execution quality
