Your Guide to Email Marketing ROI

Do you ever wonder if your emails are making money? That's what Email Marketing ROI shows you. It is a simple way to see how much profit you make from your email campaigns. You compare this to what you spent to send them.

Think of it like this: for every dollar you put in, how many do you get back? New data shows that email marketing brings in a huge $36 for every $1 spent. It is the most important number for proving your marketing is working.

What Email Marketing ROI Really Means

Picture your email strategy as a machine. You put a little money into it. This money pays for your email platform or for someone to write good emails. In return, that machine makes money from customers who buy things because of your emails.

Email marketing ROI (Return on Investment) tells you how well that machine is running. It answers one big question: "Is this making us money?"

Why This Number Matters So Much

Figuring out your email ROI is not just for data experts. It is a tool that helps everyone make better choices. This is true for small business owners and big company managers.

Knowing your ROI helps you do these things:

  • Justify Your Spending: You can show your boss exactly how money spent on email turns into real profit.
  • Make Smarter Investments: Do you see which campaigns are doing great? A high ROI tells you where to spend more money.
  • Catch Problems Early: If your ROI starts to go down, it is an early warning. It could mean your subject lines are boring or your offers are not good. This gives you a chance to fix it.

ROI turns your marketing work into a clear business story. It connects sending an email to growing your company. It proves that your work is a profit center, not just a cost.

Tracking this number is the only way to know if your email plan is helping your business grow. Without it, you are just guessing.

How to Calculate Your Email Marketing ROI

Are you ready to see how much money your emails are making? Don't worry. Figuring out your email marketing ROI is not as hard as it sounds. It comes down to a simple formula. The formula compares what you earned to what you spent.

The main idea is easy to understand:

ROI = (Money Made from Email – Total Cost) / Total Cost

Just multiply the final number by 100 to get a percentage. This simple math gives you a powerful number. It shows the exact return you got for every dollar you put into your emails.

How powerful is it? Most businesses see an average ROI of about $36 for every $1 spent. That is a huge 3,600% return. You can learn more about this on sites like emailmonday.com.

Getting the Numbers Right

To get the right ROI, you must be honest about both parts of the formula. You need to know what you gained and what you spent.

  • Money Made from Email (The Gain): This is all the money that came directly from an email or campaign. If you have an online store, you can track sales that came from a link in your email.

  • Total Cost (The Investment): This is where people often make mistakes. It is not just the price of your email software! A real cost includes everything you spent.

To get the full picture of your spending, be sure to include:

  • Fees for your email service provider (like Mailchimp or Klaviyo).
  • Pay for writers, designers, or marketing helpers.
  • Any money spent on ads to get emails for your list.

A Quick Calculation Example

Let's look at a simple example. Imagine you have an online clothing store. You send an email about a new line of shirts.

You spent a total of $200 on this campaign. This cost includes part of your software fee and a small payment to a designer. That one email made $2,200 in sales.

Here's how to figure out your ROI:

  1. Find your net profit: $2,200 (Revenue) - $200 (Cost) = $2,000
  2. Divide profit by the cost: $2,000 / $200 = 10
  3. Turn it into a percentage: 10 x 100 = 1,000%

That’s an ROI of 1,000%! For every dollar you spent, you got $10 back. That's very good.

This table shows the numbers in a clear way.

Simple Email ROI Calculation Example

MetricAmountDescription
Total Revenue$2,200The total sales from the email campaign.
Total Cost$200Includes software fees and a designer's fee.
Net Profit$2,000Calculated as Revenue minus Cost ($2,200 - $200).
ROI (as a ratio)10The result of Net Profit divided by Cost ($2,000 / $200).
ROI (as a percentage)1,000%The final return on investment (10 x 100).

The math is simple. But the information it gives you is very important. Tracking this number is a key part of a good email plan. It is one of several key email marketing performance metrics to track in 2025 that we talk about in our guide.

Okay, you have your email marketing ROI number. Now what? The big question is, "Is this a good number?"

There is no single magic number for everyone. A great ROI for a software company might be just okay for an online store. It depends on your industry and who your customers are.

You have probably heard the big number: a $36 return for every $1 spent. It is a great number that shows how powerful email can be. But you should treat it like a national weather report. It is a helpful guide. But you need the local forecast to know what is happening in your area.

How Do You Stack Up? Industry Benchmarks

Email results can be very different depending on your business. A store sending out sale announcements will see different results than a news company sending a daily email.

Let's look at what a "good" ROI looks like in a few areas:

  • Retail & Ecommerce: These businesses are often the leaders. They get an average ROI of 45:1. This makes sense. They send offers that lead right to a sale.
  • Marketing & Advertising Agencies: They see a great return of around 42:1. They use email to build strong relationships with clients.
  • Software & Technology: These companies usually get around 36:1. They use email to help new users get started and to sell more features.
  • Media & Publishing: A solid 32:1 ROI is common here. Newsletters drive people back to their websites and sell subscriptions.

Here is the thing about benchmarks: they are a guide, not a goal. The real goal is not to hit an industry number. It is to beat your own number from last month. A lower ROI that is growing is a better sign than a high one that has been flat for a year.

Proven Strategies to Increase Your Email ROI

Once you know your numbers, you can start making them grow. Making your email marketing ROI bigger is not about a secret trick. It's about using smart tactics that work together to get better results.

You can turn your email list into a real money-maker. Focus on sending the right message to the right person at the right time. Let's look at some of the best ways to do this.

Segment Your Audience for Super-Relevant Messages

Sending the same email to everyone is not a good idea. It is like shouting in a crowded room. You hope the right person hears you. Segmentation is the simple trick of splitting your subscribers into smaller groups. These groups are based on things they have in common.

This lets you send messages that really speak to their interests. You can group people by many things:

  • Purchase History: Send special offers to loyal customers. Or suggest products based on what they bought before.
  • Demographics: Change your message based on a person's location, age, or gender.
  • Engagement Level: Give your biggest fans special deals. Or try to win back people who have not opened an email in a while.

This targeted plan makes your subscribers feel important. That leads to better open rates, more clicks, and more sales.

A/B Test Everything to Find What Works

Never guess what your audience wants. A/B testing is your best friend. This means you create two different versions of an email. You send them to a small part of your audience. Then you see which one does better.

The best email marketers don't guess—they test. A small change to a subject line or a button can lead to more sales. This gives you a higher ROI.

The key is to test only one thing at a time. It could be the subject line. It could be the button text. It could even be the main picture. Once you have a clear winner, you can send that version to the rest of your list.

Embrace the Power of Automation

Automated emails are sent on their own. They are based on what a person does or on a timeline. They are also called drip campaigns. Think of them as your 24/7 marketing team. They work in the background to build relationships and make sales. The proof is there: 50% of people bought something from a marketing email last year. This shows how big the impact can be. You can learn more about this and the fact that nearly 4.5 billion people use email on OptinMonster.

Here are a few automated emails every business should have:

  • Welcome Series: Say hello to new subscribers right away. Give them a friendly introduction to your brand.
  • Abandoned Cart Reminders: Remind customers who left items in their cart to come back and buy.
  • Post-Purchase Follow-ups: Thank customers for their order. Ask for a review. Or suggest other products they might like.

Setting up these emails is a one-time job that keeps paying off. For more ideas, read our guide on drip campaign best practices for maximum ROI in 2025.

As you can see in the chart below, the average email ROI can be very different across big industries. Retail often leads the group.

The data clearly shows that online stores often see amazing returns. But B2B and software companies are not far behind. They also get a great ROI that proves email works for everyone.

Common Mistakes That Lower Your Email ROI

Sometimes, the fastest way to a better email marketing ROI is not a new trick. It is fixing the problems in your current plan. Many common mistakes can hurt your results. They turn a strong tool into a waste of money. Finding these problems is the first step to fixing them.

One of the most common mistakes is sending too many emails. This makes subscribers tired of you. It teaches your audience to ignore you or unsubscribe. It is always better to send fewer, better emails with real value.

Ignoring mobile phones is another big mistake. Over 40% of emails are now opened on a phone. An email that looks bad on a small screen will be deleted. A bad mobile experience is a sure way to lose someone's attention.

Forgetting to keep your list healthy is like building a house on a weak foundation. Simple mistakes can cause big problems. They slowly eat away at your possible returns.

Unhealthy List Practices

An unhealthy email list is a silent ROI killer. Your list might have many people who never open your emails. This makes your engagement numbers go down. It can also hurt your sender reputation. That makes it harder to reach the people who do want to hear from you.

Here are a few list mistakes to avoid:

  • Never, ever buy email lists. These lists are full of people who are not interested. They will mark your emails as spam. This is a fast way to get your account flagged and hurt your ability to reach real customers.
  • Forgetting to clean your list. You have to clean your list often. Removing people who have not opened an email in months is important. It keeps your numbers honest and your list healthy.
  • Making it hard to unsubscribe. Hiding the unsubscribe button is a bad idea. It just makes people angry. They often report you as spam instead, which is much worse.

Fixing these basic problems is key to making sure your emails get delivered. For more help, check out our guide on how to improve email deliverability and avoid spam.

Got Questions About Email ROI? We've Got Answers.

Even expert marketers have questions about email marketing ROI. The idea seems simple. But the details can be tricky. Let's answer a few of the most common questions we hear.

Think of this as your quick guide for email ROI.

How Often Should I Be Calculating My Email ROI?

This is a great question. The honest answer is: it depends on your business. But a good rule is to check your ROI monthly. This gives you enough information to see trends. You will not get lost in daily changes.

But you should also check the ROI for specific, important campaigns. This gives you quick feedback. For example:

  • Holiday Sales: Did that Black Friday sale really make money?
  • New Product Drops: How much money did your launch email really bring in?
  • A/B Tests: Which subject line made more money, not just more opens?

So, What's a "Good" Email Marketing ROI, Anyway?

You will see the big number everywhere: $36 for every $1 spent. That is a great industry number. But a "good" ROI is not the same for everyone. It is all about your business.

A retail store, for example, might get a huge 45:1 return during a big sale. A B2B company might see a lower number. But that number could still be very good for their business.

The most important number is not an industry average; it's your own past results. Your goal should be to grow slowly and steadily. If you are doing better than last month, you are winning.

What Tools Do I Actually Need to Measure This?

Good news: you probably already have what you need. You do not need fancy or expensive tools to see your ROI.

Most modern email platforms have good analytics built in. These include tools like Klaviyo, Mailchimp, or beehiiv. The magic happens when you connect your email tool to your online store (like Shopify) or your website analytics.

You will need at least three things:

  1. Your Email Platform: This is where you send emails and track clicks.
  2. Website Analytics: Something like Google Analytics is perfect for tracking who buys.
  3. A Simple Spreadsheet: To track your costs and do your final ROI math.

Many email platforms now track sales for you. This makes the whole process easier than ever before.
