A/B testing—if you’re not doing it already, you’re leaving money on the table.
Seriously, A/B testing is one of the most powerful tools in your e-commerce email marketing toolkit. It’s all about fine-tuning your campaigns to see what works best with your audience, and the insights you can gain are pure gold. But where do you start? With so many variables to test, it can feel a bit overwhelming. Don’t worry, I’ve got you covered. Let’s dive into some practical A/B testing ideas that can help you optimize your e-commerce email campaigns and boost your results.
Test Your Subject Lines: The Gateway to Opens
Let’s kick things off with subject lines. Your subject line is the first thing your audience sees and often determines whether they’ll even open your email. Even small tweaks can lead to significant differences in open rates.
Here’s an idea: test different types of subject lines. Compare a straightforward, descriptive subject line like “20% Off All Summer Styles” with something curiosity-driven like “Your New Favorite Outfit Awaits.” Or try testing urgency with “Last Chance to Save 20%” versus “Don’t Miss Out on 20% Off.”

Experiment with Send Times: When Are Your Subscribers Most Active?
Timing can make or break your campaign. While general guidelines exist, your audience may have unique habits. This is where A/B testing proves invaluable.
Try testing morning sends versus afternoon or evening sends. You could also test weekday emails against weekend ones to see what resonates with your subscribers. Dive into The Best Time to Send E-commerce Marketing Emails for data-backed insights.
Play with Different CTAs: What Drives Action?
Your call-to-action (CTA) is the tipping point of your email—the moment you encourage your reader to take the next step, like making a purchase or clicking through.
Test different CTA phrases like “Shop Now” versus “Claim Your Discount” to see which drives the most clicks. You can also experiment with button placement—does it perform better at the top or the bottom of your email?

Vary Your Email Length: Short and Sweet vs. Detailed and Informative
Some audiences love quick, to-the-point emails, while others prefer detailed information to make an informed decision.
Try A/B testing a short version of your email that highlights key points against a longer one with more details and visuals. Need help organizing your campaigns effectively? How to Build an Effective Email Marketing Funnel for E-commerce provides a roadmap for structuring your content.
Test Different Offers: Discounts vs. Free Shipping
Promotional offers are prime candidates for A/B testing. For example, you can test a percentage discount like “20% Off” against a dollar discount like “Save $10.” Or compare free shipping with a buy-one-get-one-free (BOGO) deal.
