If your email list isn’t making money… you’re probably making one (or more) of these mistakes.

In this episode of Boss Lady Social, Courtney Sjoberg Davini breaks down the most common email marketing mistakes she sees as a fractional CMO working with online business owners, coaches, and creatives.

Email marketing is NOT dead, but most people are using it wrong.

From inconsistent email schedules to poor subject lines to relying too heavily on social media, these mistakes are quietly killing your conversions.

The good news? Most of them are simple fixes that can dramatically increase your sales.

In this episode, you’ll learn:

  •  Why email marketing still has the highest ROI in 2026 
  •  The real difference between Instagram reach vs email reach 
  •  How often you should actually be emailing your list 
  •  Why only emailing during sales is hurting your business 
  •  How many emails you should send during a launch 
  •  Why cleaning your email list improves deliverability 
  •  How segmentation and tagging increase conversions 
  •  Why talking to “everyone” is lowering your engagement 
  •  How to understand your email metrics (open rates, clicks, etc.)

  •  How to write better subject lines that get opened 
  •  Why plain text emails outperform overly designed emails

Hello, hello, hello, and welcome back to Boss Lady Social. I’m your host, Courtney Sjoberg Davini.

I’m a fractional CMO, and I help women build revenue systems that actually convert, not just content that looks good.

And today, we’re talking about email marketing.

Now I know some of you are already rolling your eyes thinking… “email is dead.”

It’s not.

If you’re not using your email list, you’re ignoring the most profitable channel in your business. In 2026, email marketing still averages $36 to $42 for every $1 spent, which is honestly insane.

And another thing people forget… you don’t own your social media. Platforms like Instagram or TikTok can tank your reach, shut down your account, or change the algorithm overnight.

Your email list? That’s yours.

And it converts higher. Email is usually around 1 to 5 percent or more, and social is typically under 1 percent.

So let me put this into perspective.

If you have 1,000 Instagram followers, maybe 100 to 300 people will actually see your post.

But if you email 1,000 people, about 800 or more are going to get that email, and 300 to 500 will actually open it.

That’s not even comparable.

So if your email list isn’t making money, it’s probably one of these reasons. I see these patterns constantly with my clients, and the craziest part is that small tweaks make really big results. If you fix even two or three of these, your email list can start making money. Period.

The first one is strategy… or honestly, lack of strategy.

A lot of you don’t have a clear email schedule. You’re either randomly emailing, ghosting your list for months, or only showing up when you want to sell something. And people can feel that. That energy of “hi, I only care about you because I want money” is not it.

And on the flip side, if you are emailing during a sale, you’re probably not sending enough.

I had a client who sent two or three emails for a launch. We bumped that to seven to fifteen, and that’s where the sales came from.

You’re either ghosting or panicking, and neither one converts.

The next issue I see all the time is bad list management.

First, you have to clean your list. I know people hate doing this, but if someone hasn’t opened your emails in months, they’re not your people right now. Removing them actually helps your open rates, helps your deliverability, and keeps you out of spam.

And then there’s segmentation and tagging. You don’t need anything super advanced, but if you’re not organizing your audience at all, you’re leaving money on the table.

Another big one is how you’re writing your emails.

You’re talking to everyone instead of one person.

Stop saying “hey everyone.” Talk to one person. Write like you’re texting a friend. That shift alone will change how your emails feel and how they convert.

Then there’s your numbers.

You need to know your open rate, your click rate, and what’s actually working. If your open rate is high but your clicks are low, your content isn’t converting. And that’s where you tweak.

That’s honestly how I built my business. I try something, I look at the data, I tweak it, and I repeat.

And speaking of data, most of you are not tracking anything.

You should be using Google Analytics and UTM links so you actually know where your sales are coming from. Which email worked, which platform drove traffic… guessing is not a strategy.

Then we have email execution.

Too many graphics will land you in spam. Keep it simple. Plain text emails win.

Your subject line is everything. It’s your hook. If your subject line isn’t good, nothing else matters because no one is opening the email.

And if you’re not customizing your preview text, you’re missing an easy opportunity to increase your open rates.

And finally… this one drives me insane.

So many people are putting more effort into social media than their email list.

It should be the opposite.

Social media is where you get attention. Email is where you make money.

You should be using your social platforms to grow your email list, not relying on them for all of your sales, because social is unpredictable.

If you want consistent sales, you need an ecosystem.

Social brings in attention. Email converts. Long-form content builds trust.

That’s how this works.
