5 Email Marketing Mistakes You’re Making But Questera Resolved

In 2025, over 4.5 billion people will use email every day. That’s nearly half the world checking inboxes, clicking links, and scanning subject lines. So yes, email is still one of the most powerful ways to reach people. Unfortunately, even with all that potential, many teams are still making basic email marketing mistakes.

It’s easy to slip up. A wrong subject line, sending too often, or talking to the wrong group of people. We’ve seen these marketing mistakes over and over again. And most of the time, brands don’t even know they’re making them.

How to find email marketing mistakes before they hurt your results. Because if you're not careful, a few small slips can lead to big email marketing problems. Today, we’re walking through the top mistakes in marketing and how to fix them. We’ll keep it simple, real, and right to the point.

Top 5 Email Marketing Mistakes Questera Can Resolve

The biggest question most teams face is how to find email marketing mistakes before they start losing clicks, trust, and sales. It’s not always clear what’s going wrong or why emails aren’t working. So, we’ve listed the top 5 email marketing mistakes and shared exactly how Questera’s AI agents solve each one.

1. Not Segmenting Your Audience

Different people are at different points in their journey. Some just heard about your brand yesterday. Some are thinking about buying. Others already made a purchase and might come back again. If all of them get the same message, most of them won’t care. They won’t click. Some might even unsubscribe. This is one of the most common email marketing mistakes, and it hurts more than people think.

If you’re wondering how to find email marketing mistakes like this, start by looking at your open rates and click-throughs. If they’re low, this could be the reason. It’s a quiet marketing mistake, but it creates big email marketing problems down the line.

That’s why SEGA, our segmentation agent, watches user behavior closely. It looks at who’s browsing, who’s buying, and who’s just looking around. Then, it puts each person into the right group. Someone who added an item to their cart but didn’t buy won’t get the same email as someone who just left a five-star review.

This helps stop sales email mistakes before they happen. It also takes a huge load off your team. You’re not guessing anymore. You’re sending better emails because you know who you’re talking to. And when you do that right, people notice. They click more. They buy more. That’s how you stop repeating the same mistakes in marketing again and again.

2. Sending Irrelevant or Generic Content

It happens more often than you’d think. A person gets an email about a product they’ve never looked at or a feature they don’t even use. What do they do? They skip it. Or worse, they stop opening your emails altogether.

This is one of those email marketing mistakes that slowly eats away at your results. People get bored. They feel like you’re not really paying attention. And over time, that leads to low engagement and bigger email marketing problems. When content feels off, users check out fast. It’s hard to win them back once that happens.

This kind of marketing mistake is hard to spot if you’re sending the same message to everyone. That’s why ELMA, our email lifecycle agent, looks at each user’s journey. She checks where they are and how they’ve been interacting. Someone who just signed up gets a different email than someone who hasn’t been active in weeks.

Once ELMA figures that out, she works with BECCA and PECCA. They’re the content creators. They write in a way that feels human. The message fits the user. The product recommendations make sense. The words feel like they were written just for that person.

3. Relying on Basic Automation

A lot of teams still depend on basic automation. They build one email flow and let it run for everyone. It might work at first, but over time, things change. People click less. They stop responding. The flow keeps going, but the results drop.

This is one of the quieter email marketing mistakes, and it often goes unnoticed. Most teams don’t realize it’s a problem until performance takes a dive. And by then, it’s hard to catch up. This kind of marketing mistake leads to missed chances, bored users, and lower sales.

The truth is, people behave differently every day. What they do today isn’t always the same as what they’ll do next week. That’s why basic flows don’t cut it anymore. They’re too slow to keep up. You can’t fix email marketing problems if your emails don’t adjust in real time.

AI agent, OMNIA, watches what people are doing across email, ads, and push notifications. She tracks clicks, opens, visits, and drop-offs. When someone changes their behavior, she updates the journey right away. If a person stops engaging, OMNIA tries a new path. If they show high intent, she nudges them closer to conversion.

This avoids a ton of common sales email mistakes. You’re not stuck with outdated logic. You’re not guessing. You’re reacting to what people are actually doing. That’s how you avoid repeating the same mistakes in marketing again and again. And that’s how you stay one step ahead, without running in circles.

4. Ignoring Data and A/B Testing

A lot of teams skip A/B testing. They don’t look at the numbers. They just send and hope for the best. That kind of guesswork leads to the same email marketing problems again and again.

If you’re not learning from what’s working, you’re probably repeating the same email marketing mistakes without even knowing it. Maybe the subject line was too long. Maybe the button was in the wrong place. Maybe people didn’t care about the product you were showing. You’ll never know unless you test.

This marketing mistake is easy to fall into, especially when things get busy. But here’s the thing. If you’re not testing, you’re not improving. And if you’re not improving, you’re falling behind. That’s the honest truth.

GIA, our data insights agent, looks at every email and every click. She finds patterns in what people open, what they ignore, and what they engage with. She spots what’s working and what’s not. She even suggests what to change, like trying a shorter subject or switching the time you send.

Then ELMA picks it up from there. She adapts your emails based on what GIA finds. No extra effort needed. No digging through spreadsheets. Just smarter campaigns that learn as they go.

5. Wrong Email Frequency (Too Many or Too Few)

Sending emails too often or not enough- this happens more than you think. Some brands send emails every other day, thinking more is better. Others wait so long between emails that people forget who they are. Both are big email marketing mistakes.

Too many emails and people feel annoyed. Too few, and they lose interest. Either way, the result is the same: low engagement and rising unsubscribes. These are the kinds of email marketing problems that are hard to undo. Once someone tunes you out, it takes a lot to bring them back.

This kind of marketing mistake is tricky because it’s hard to guess what’s “too much” or “too little.” That’s why ELMA pays close attention to user fatigue. She watches how people react. If someone is opening everything, she might send a bit more. If someone stops clicking, she slows it down.

She also looks at re-engagement. If a user has gone quiet, ELMA times her messages just right. Not too early, not too late.

This fixes one of the most common sales email mistakes treating everyone the same when it comes to timing. It also solves one of the hardest email marketing challenges, knowing when enough is enough.
