If you’re running an e-commerce business such as an online store, you’ve probably heard this a million times—email marketing still works. Even with social media and flashy new digital trends, email remains one of the most effective ways to connect with customers, drive sales, and build loyalty. And the numbers back it up. For every $1 spent on email marketing, businesses see an average return of $42. That’s a really good ROI!
Why Email Marketing is a Game-Changer for E-Commerce

1. High ROI Without Breaking the Bank
Let’s be honest—marketing budgets can be tight, especially for small businesses. The good news? Email marketing is one of the cheapest and most effective ways to reach customers. Unlike paid ads, where costs keep adding up, emails allow you to connect with your audience for almost nothing (except for the cost of an email platform). And when done right, the returns can be huge.
2. Personalized Emails That Actually Get Read
Nobody likes spammy, one-size-fits-all emails. That’s why personalization is key and the way you do it makes a lot of difference. Imagine this: You browse an online store, add a product to your cart, but leave without buying. A day later, you get an email with “Still thinking about this?” in the subject line and a 10% off coupon. Feels personal, right? That’s the power of email segmentation and behavior-based targeting.
3. Automation Makes Your Life Easier
If you’re not automating your emails, you’re leaving money on the table. Tools like HubSpot let you set up email workflows that run on autopilot—whether it’s a welcome email for new subscribers, abandoned cart reminders, or post-purchase follow-ups. Once set up, they do the heavy lifting for you.
How to Create an Email Marketing Strategy That Works

1. Build a High-Quality Email List
Buying email lists? Big mistake. Not only does it hurt your reputation, but most of those emails will never convert. Instead, grow your list organically by:
- Offering a discount in exchange for sign-ups.
- Running a giveaway or contest.
- Creating free content (like an eBook or guide) that people want.
2. Write Subject Lines That Grab Attention
Your email is worthless if nobody opens it. The subject line is the first thing people see, so make it count. Try these tricks:
- Keep it short (under 50 characters).
- Use curiosity or urgency (“Hurry! Your 15% off expires tonight”).
- A/B test different subject lines to see what works best.
3. Make Sure Your Emails Look Good on Mobile
More than 60% of emails are opened on phones. If your email isn’t mobile-friendly, people won’t bother reading it. Keep it clean, use clear CTA buttons, and avoid long blocks of text.
4. Use Segmentation to Send the Right Emails to the Right People
Not every subscriber is the same. Some are first-time visitors, while others have been loyal customers for years. Sending the same email to both? A missed opportunity. Instead, segment your list by:
- Purchase history – Send product recommendations based on past buys.
- Engagement level – Re-engage inactive subscribers with a special offer.
- Location – Offer location-specific deals or event invites.
5. Set Up Automation for Maximum Impact
Some emails should be sent automatically based on customer actions. Here are three must-have automation sequences:
✔ Welcome Series – Greet new subscribers with a warm intro + special offer.
✔ Abandoned Cart Reminders – Nudge shoppers to complete their purchase.
✔ Post-Purchase Follow-Ups – Ask for reviews, offer product care tips, or suggest related items.
How Email Marketing Directly Boosts Sales

1. Recovering Abandoned Carts (aka Saving Lost Sales)
Over 70% of online shoppers leave their cart without checking out. That’s a huge chunk of lost revenue. But abandoned cart emails can help win them back. Adding a small discount or free shipping in these emails often does the trick.
2. Upselling & Cross-Selling Like a Pro
Ever bought something online and then received an email suggesting related items? That’s upselling and cross-selling in action. Let’s say someone buys a Hoodie, why not send them an email featuring the best men’s t-shirts as a complementary product that can drive additional sales? It works.
3. Keeping Customers Loyal
Loyal customers spend more and buy more often. A smart email strategy keeps them engaged with exclusive discounts, early product drops, and VIP perks. Rewarding them keeps them coming back. Also, you can use FOMO (Fear of Missing Out) to your advantage if you execute it strategically.
Final Thoughts: Is Email Marketing Still Worth It? 100% Yes.
If you’re serious about growing an e-commerce business, email marketing isn’t optional—it’s a must. From recovering abandoned carts to keeping customers loyal, email remains one of the most effective and affordable ways to drive sales.
