Bostech Auto

EMAIL MARKETING CASE STUDY

Merchant Summary

Bostech Auto is a trusted supplier of high-quality diesel parts for trucks, vans, RVs, and commercial vehicles. With a product line that includes fuel pumps, HPOPs, and EGR coolers, they serve a critical role in helping customers keep diesel engines running efficiently. While their catalog remained strong, declining revenue and email performance signaled it was time to reevaluate their marketing efforts—especially in a rapidly evolving email landscape.

Main Challenges

When Bostech Auto first approached EYStudios, their primary concern was a noticeable and sustained decline in overall revenue. As a company with a strong product catalog and a history of success, this downward trend was concerning and signaled the need for a strategic intervention.

Challenge #1

Dormant Campaign Outreach

Despite maintaining an active Klaviyo account, Bostech Auto failed to send a single email marketing campaign since 2023, completely stalling manual brand outreach.

Challenge #2

Authentication Disruptions

New industry email authentication policies introduced in 2024 broke the company's backend setup, blocking their ability to successfully deliver automated messages.

Challenge #3

Halted Automated Flows

Critical, high-intent automated sequences, such as welcome messages and abandoned cart reminders, failed completely, cutting off core customer touchpoints.

Challenge #4

Lost Revenue and Retention

With zero structured outreach and stalled engagement, Bostech Auto suffered from major losses in both immediate sales opportunities and long-term customer retention.

Our Creative Approach:

Bringing Clarity and Consistency to Email Marketing

To re-establish email as a revenue-generating channel, EYStudios took a strategic, multi-phase approach.

1. Domain Update & Authentication

The first and most critical step was to resolve deliverability issues by updating and authenticating the client’s sending domain to align with new email standards.

2. Flow Development

With foundational functionality restored, our team then moved swiftly to redesign and deploy a complete set of automated flows tailored to the customer lifecycle.

A robust welcome series for new subscribers.
Custom abandoned cart sequences to bring shoppers back to their missed purchases.
Customer winback emails for lapsed customers.
Personalized post-purchase follow-up emails.
Browser abandonment prompts.
Product review request emails.

These flows run automatically, helping Bostech Auto build relationships and generate revenue with minimal effort.

3. Campaign Strategy & Improved Segmentation

Once those automated systems were live and optimized, we shifted focus to campaign consistency, developing a recurring calendar of promotional and informational emails designed to keep the brand top-of-mind and drive repeat purchases. Simultaneously, we implemented improved list-building strategies to boost signup.
