Why Email Marketing Crushes Other Channels

Forget what the gurus say—email isn’t dying. It’s evolving, and it’s still the highest-performing marketing channel for eCommerce brands.

Everyone’s Still on Email

There are over 4 billion daily email users, projected to hit 4.6 billion by 2025. That’s more reach than TikTok, Instagram, or any social platform.

More importantly? You’re not fighting an algorithm.

Email lands in inboxes, not newsfeeds—giving you full control over who sees what and when.

Personalization That Performs

Email marketing lets you go deep.

• Show products they browsed
• Recommend bundles based on past orders
• Automate birthday emails
• Add dynamic coupons

Stats don’t lie: Personalized emails deliver 6x higher transaction rates and can double your ROI.

You Can Scale Without Bleeding Budget

Unlike paid ads that get more expensive as you grow, email lets you scale smarter.

• New product launch? One email = thousands of clicks.
• Welcome flow? Automated, evergreen.
• Want to test a campaign? A/B test for $0 in real-time.

Whether you’ve got 1K or 100K subscribers, email scales with you—not against you.

The 3-Part Email Strategy That Builds Revenue Daily

1. Automations That Run While You Sleep

Set up once. Generate revenue forever.

Must-Have Automated Flows:

Klaviyo says automated emails drive 14x more revenue per recipient than batch campaigns. Don’t sleep on these flows.

2. Campaigns That Feel Human

Campaigns are your way of showing up, telling stories, and driving action.

Run weekly, bi-weekly, or monthly—just stay consistent.

Ideas to Fuel Campaign Content:

• New product drops
• Seasonal promos
• Educational “How To” emails
• Founder letter or behind-the-scenes
• UGC roundups and review highlights
• Countdown to limited drops

Golden Rule:

Every campaign should do at least one of the following:

✅ Deliver value
✅ Inspire action
✅ Strengthen your brand

3. Test Everything (Because Guessing Is Expensive)

Think “10% off” always wins? Test it against “$5 off.”
Think your black CTA button converts best? Test green.
Think your Tuesday morning sends work? Try Sunday night.

What You Should Be Testing:

A/B testing removes guesswork. Every small win compounds over time.

Advanced Email Tactics for Smarter Brands

Segmentation That Actually Matters

Not all segmentation is created equal.

Skip “Male vs. Female” and try:

• First-time vs. repeat buyer
• Last product purchased
• LTV over $200
• Region-based weather segmentation (sell jackets to Canada, swimsuits to Florida)

Segmentation = relevance. Relevance = revenue.

Personalization Beyond “Hey, [First Name]”

Dynamic personalization ideas:

• “We saw you looking at [Product]”
• “Here’s 15% off to complete your order”
• “Because you bought [X], you’ll love [Y]”
• “Back in stock: Your favorite [color] in [size]”

Tools like Klaviyo make this easy with native integrations and conditional logic.

Build Email Like a Product

Your email list = your owned asset.

Build it like your product:

• Clean your list every 90 days
• Monitor open, click, unsubscribe trends
• Focus on quality over quantity
• Optimize forms for conversion

Lead capture tip: 2-step popups (email → SMS) convert higher than single-step forms.

Real Brands, Real Results (Case Studies)

Frequently Asked Questions

1. How many emails should I send per week?
Start with 1–2 campaigns. Let automation do the heavy lifting behind the scenes. Over-send and risk unsubscribes; under-send and lose momentum.

2. What’s the best ESP (email platform) for eCommerce?
Klaviyo is the go-to for Shopify brands. It supports automation, segmentation, A/B testing, and SMS in one dashboard.

3. What’s a healthy open/click rate?

• Open Rate: 30–50%
• Click Rate: 3–6%
• Conversion Rate: 1–3%
  Lower than that? Time to test.

4. How do I avoid going to spam?

• Use double opt-in
• Avoid spammy subject lines (“FREE!!”)
• Send consistently
• Use clean lists (no bought contacts)

5. Should I combine email and SMS?
Yes. Email for deep storytelling, SMS for urgency. Together, they increase customer touchpoints and conversion.

6. How do I grow my list fast—but ethically?

• Offer lead magnets (discounts, guides)
• Use exit-intent popups
• Add embedded forms to blogs and product pages
• Incentivize referrals or social shares

Final Take: Email Is the Compounding Asset Most Brands Ignore

While most brands obsess over trends, the smart ones are doubling down on what works every time—email.

It’s not just about clicks or conversions.
It’s about owning your audience.
Building relationships.
Driving predictable revenue every month.

No algorithms. No guesswork. Just strategy and execution.
