Why Email Marketing Is Still the Most Underutilized Channel in Ecommerce

When it comes to growing your brand, paid ads and social media tend to get all the attention. But the most effective, highest-ROI channel? It's email marketing—and most ecommerce brands are barely using it to its full potential.

At Milhook, we specialize in turning email into a top-performing revenue engine for DTC brands. In fact, 20–40% of total revenue should come from your email marketing efforts. If you're not seeing that, there's untapped growth waiting for you.

What Makes Email Marketing So Powerful?

1. Email Delivers the Highest ROI

According to industry reports, email marketing delivers an average ROI of $36 for every $1 spent—higher than any other marketing channel. With no ongoing ad spend and low production costs, email campaigns can turn profits quickly and repeatedly.

2. You Own Your Email List

Unlike social platforms or paid ads, email is a channel you fully control. Your list isn't affected by algorithm changes or platform policies. You can reach your audience directly, when and how you want.

3. Email Builds Long-Term Customer Loyalty

Automated email flows like welcome series, abandoned cart emails, post-purchase follow-ups, and re-engagement campaigns help keep your brand top-of-mind. These flows increase customer lifetime value (LTV) and build deeper customer relationships over time.

4. Segmentation and Personalization Drive Conversions

Modern email platforms like Klaviyo allow for powerful segmentation and personalization, so your messages land at the right time, with the right content, for each user. Personalized emails generate 6x higher transaction rates.

5. It Supports Every Stage of the Funnel

Email is one of the few tools that works across the entire customer journey—from acquisition and conversion to retention and reactivation. It can tell your brand story, showcase products, offer incentives, and bring customers back—all without paying for another click.

Why Most Brands Underuse Email Marketing

Despite its potential, email marketing remains one of the most underutilized marketing channels. Here’s why:

• Many brands only send occasional newsletters.

• Automated flows are missing or outdated.

• Campaigns lack clear goals or optimized design.

• There's no A/B testing or segmentation.

• Email is treated as a last-minute task instead of a strategic channel.

This leaves thousands of dollars in lost revenue on the table every month.
