Why Email Marketing Matters for T-Shirt Brands

Before diving into the comparison, let’s explore why email marketing is a game-changer for clothing brands, especially those in the D2C T-shirt space:

• High ROI: Email marketing delivers an average ROI of $36 for every $1 spent.
• Direct Channel: You own your email list—no algorithms or ads stand between you and your customers.
• Personalization: Target customers based on behavior, preferences, or purchase history.
• Retention & Repeat Sales: It’s easier (and cheaper) to get a past customer to buy again than to acquire a new one.

Whether you’re selling minimalist Supima T-shirts or bold streetwear designs, the right email tool can significantly impact your growth.

Our Recommendation: Omnisend Wins for Most T-Shirt Brands

Unless you’re running a high-volume, multi-country clothing brand with a dedicated marketing team, Omnisend is the smarter choice for 90% of T-shirt businesses.

Why Omnisend?

• Affordable Scaling: Get all the tools you need—email flows, SMS, push notifications, forms—without breaking the bank.
• Ease of Use: Even if you’re just starting, Omnisend’s interface makes it easy to launch campaigns in minutes.
• Complete Toolset: No need for additional plugins or platforms to get started.
• Good Enough Segmentation: For small to mid-sized brands, Omnisend’s segmentation is more than sufficient.

However, if you’re already at scale and need predictive analytics, in-depth reporting, or advanced testing capabilities, Klaviyo is worth the investment.

Real Example: Why We Chose Omnisend

At Offnorth Fashions, a D2C T-shirt brand known for Supima and Bamboo cotton apparel, we evaluated both tools in 2024. While Klaviyo impressed us with its depth, the costs didn’t justify the benefits at our revenue stage.

Omnisend offered:

• Easier onboarding for our team.
• Reliable delivery of automation emails.
• Ability to nurture and convert leads at a fraction of the cost.

With Omnisend, we achieved:

• Setup of 6 automation flows within 2 days.
• Growth of our email list from 300 to 3,000 in 6 months.
• Conversion of 18–22% of abandoned carts through emails alone.

Final Thoughts

Choosing the right email marketing platform depends on your brand’s current stage and future goals. For most growing T-shirt brands, Omnisend offers the perfect blend of functionality and affordability. You get everything needed to build an engaged customer base, drive repeat purchases, and hit significant revenue milestones.

However, if you’re running a large-scale operation or are obsessed with advanced data modeling and segmentation, Klaviyo provides that extra edge.

Both platforms are excellent—it’s about choosing what aligns with your growth stage.
