Email marketing is one of the most profitable channels for ecommerce brands. But here’s the problem: most brands are stuck believing outdated myths that cost them revenue, weaken their customer relationships, and stall long-term growth.

After auditing hundreds of accounts at ASPEKT, I’ve seen the same mistakes play out again and again. Today, I want to break down the three biggest email marketing myths that are holding brands back, and what to do instead.

Myth #1: Always Running Sales and Promotions Works

Many brands treat sales like a magic switch they can flip whenever cash flow is tight. They push a discount or promotion two to four times a month, believing it will drive consistent sales.

Here’s the truth: always running sales cheapens your brand, slashes your margins, and trains customers to only buy during discounts.

Let’s look at it from the customer’s perspective.

• They see your ad, land on your website, and sign up through a popup to get 10% off.

• They don’t buy right away, but every week, they get bombarded with new promotions.

• Eventually, they tune out. Why? Because they know another discount is always around the corner.

At this point, your emails aren’t adding value. They’re simply another promotion clogging their inbox.

Now, here’s the bigger issue: there are only two real reasons someone doesn’t buy.

1. They don’t believe in your product.

2. They can’t justify the price.

Most brands take the easy way out by tackling the price objection, lowering it with endless sales. But no matter how deep the discount, customers won’t buy if they don’t believe your product will actually solve their problem.

Think about it like this: if I’m a size medium, you could offer me an extra-small t-shirt at 90% off. No matter the price, I won’t buy because it’s not the right fit.

Instead of training your customers to wait for discounts, focus on building trust:

• Address core pain points and desires.

• Share how your product solves real problems.

• Build credibility with reviews, testimonials, and founder stories.

When a product feels like the perfect solution, customers will pay full price, happily.

Myth #2: More Flows = More Revenue

This one’s a biggie. Too many brands think the key to scaling email revenue is creating more flows. I’ve audited accounts with 20, 30, sometimes even 50 flows live, but only a handful were actually generating revenue.

The problems with “flow sprawl” are massive:

• It’s messy. Tracking results across dozens of flows makes it nearly impossible to identify what’s working.

• It’s chaotic for customers. Multiple flows often fire at once, bombarding subscribers with conflicting messages.

• It’s inefficient. Fixing one issue means updating the same content across multiple flows.

Here’s the reality: personalization doesn’t come from having endless flows. It comes from understanding your customer deeply and speaking directly to their needs.

Instead of piling on flows, consolidate into the core revenue drivers:

• Welcome flow

• Abandonment flows (checkout, cart, browse, site)

• Post-purchase flow

• Cross-sell flow

If you want advanced personalization, tools like Klaviyo let you build dynamic content blocks inside a single flow. That way, different segments can see different products or messages without duplicating the entire automation.

Quality beats quantity every time. A handful of well-optimized, high-intent flows will outperform dozens of half-baked ones.

Myth #3: Hyper-Optimizing With Endless A/B Tests Will Scale Revenue

Don’t get me wrong, A/B testing is critical. At ASPEKT, we run ongoing tests for every client. But too many brands treat testing like a game of whack-a-mole, believing that more tests will always equal more growth.

The result? Wasted time, confusing data, and almost no meaningful lift.

There are two major problems here:

1. Testing Everything, All the Time

Some brands test subject lines one week, send times the next, email design after that, but without any real strategy. Over months, this leads to diminishing returns. Maybe they eke out a 0.1% open rate bump, but revenue barely moves.

Instead, focus on high-impact testing. For example:

• Messaging that addresses customer objections.

• Different styles of social proof (UGC vs. reviews).

• Offers that drive higher AOV.

These are the kinds of tests that actually shift the revenue needle.

2. Running Multiple Tests at Once

Here’s where brands muddy the waters. They test subject lines, content, and send times all in the same campaign. But when results come back, they can’t tell what variable actually made the difference.

Back to science class: a valid experiment needs one control and one variable. If you test three things at once, your data is meaningless.

The fix? Run one focused test at a time. Gather enough data to reach statistical significance. Then iterate. That’s how you build sustainable, compounding results.

Breaking Free From These Myths

Here’s the bottom line:

• Constant sales create short-term spikes but destroy long-term trust.

• More flows don’t equal more revenue, better flows do.

• A/B testing matters, but only when done strategically.

Email is one of the most powerful levers in ecommerce. But if you’re stuck chasing these myths, you’re holding your brand back.
