Building High-Impact Email Marketing Systems for Two Growing D2C Brands

DuyuCare.com and TryDayOne.com were launching new e-commerce stores in highly competitive markets. They needed a structured email marketing foundation that not only automated key customer touchpoints but also aligned with the fast-moving nature of D2C marketing—where attention spans are short, competition is high, and every email needs to earn its place in the inbox.

Unlike traditional email automation, where brands often set up generic welcome and abandoned cart flows, this project required a more data-driven and competitive approach to maximize engagement and conversions.

Subscribed to competitors’ newsletters to analyze their flows, content structure, and subject line strategies.

Identified gaps in their approach to ensure my clients’ emails stood out in both design and messaging.

Studied audience behavior to determine what type of incentives, email cadences, and storytelling techniques work best for their market.

For both brands, I built a full-funnel email marketing strategy using Klaviyo, ensuring that each touchpoint felt intentional and optimized for conversions.

Managed the seamless migration of past customer data from HubSpot, ensuring accurate labeling and segmentation, while simultaneously setting up automation flows to engage new users from the freshly launched website.

Structured a segmented welcome series based on whether they were past customers that I imported for them from HubSpot, or newsletter subscribers or new customers from their freshly launched website.

Optimized the abandoned cart flow with dynamic content, reminding users of what they left behind while adding urgency with limited-time offers.

Designed and implemented a subscription upgrade flow, targeting one-time buyers and existing followers with tailored incentives, educational content, and timely reminders to convert them into monthly plan subscribers.

Designed a multi-step welcome flow that gradually introduced the brand, rather than a single email that most users ignore.

Wrote click-worthy subject lines optimized for the D2C space, where open rates depend on immediacy and curiosity.

Created a discount pop-up strategy that triggered based on time spent on-site, rather than an immediate pop-up that could feel intrusive.

Designed and wrote all email content to feel on-brand, concise, and action-driven, avoiding the corporate tone that often underperforms in D2C.

Implemented A/B testing flows that could be duplicated and used in the future to test out versions of emails.

My work ensured that both brands launched with:

A deeply researched, competitive email strategy tailored for their audience.

Automated flows that feel human, not robotic sequences customers ignore.

A scalable system that enables them to drive revenue without manual intervention.

Subject lines and email structures designed for the fast-moving D2C space, ensuring they remain relevant and engaging.

Launching a D2C brand without a strategic email foundation is like running paid ads without retargeting—it leaves too much on the table. The difference between emails that convert and those that go unnoticed is not just in automation, but in how well they mirror customer psychology, competitive insights, and brand voice.
