Last Update: July 24, 2025

This article will show you the basics of A/B testing. We’ll cover what you can test, how to do tests that work, best practices, and how Send by Elementor can help you get better results.

 The Basics of A/B Testing

 What is A/B Testing?

A/B testing is like an experiment for your newsletters. You make two versions of your email: version A (the original) and version B (the change). The only thing different between the two versions is one thing you want to test. Then, you send each version to part of your audience and see which one does better.

For example, you might want to test two different subject lines to see which one gets more opens. By comparing the results, you can find out which subject line your audience likes more. This helps you make smart choices about your email marketing.

 Why is A/B Testing Important for Newsletters?

Why should you use A/B testing? It’s simple: it can really improve how your newsletters perform. By testing different things, you can learn what works best for your audience. Then, you can make your campaigns better and get better results.

Here are some key reasons to use A/B testing for newsletters:

  • Better Engagement: A/B testing helps you find out what grabs your audience’s attention. This can lead to more opens, clicks, and overall engagement.
  • Higher Conversion Rates: By improving your calls to action and content, you can get more people to do what you want, like buy something or sign up for an event.
  • Better ROI: A/B testing helps you get more for your money by making your email marketing more effective.
  • Stronger Client Relationships: If you’re a web creator, showing clients that you’ve improved results with A/B testing proves your value and builds stronger relationships.

A/B testing isn’t just nice to have; it’s important for any web creator who wants to give clients great value and build lasting partnerships.

 Key Metrics to Track

To see how well your A/B tests are working, you need to track key metrics. Here are some of the most important ones:

  • Open Rate: The percentage of people who opened your email. A higher open rate means your subject line and sender name are working well.
  • Click-Through Rate (CTR): The percentage of people who clicked on a link in your email. CTR shows how effective your content and calls to action are.
  • Conversion Rate: The percentage of people who did what you wanted them to do, like buy something or fill out a form. Conversion rate shows how successful your campaign goals are.
  • Unsubscribe Rate: The percentage of people who quit your email list. A high unsubscribe rate might mean your content isn’t relevant or interesting to your audience.

By watching these numbers, you can learn a lot about how your audience reacts to your newsletters. You can also find areas where you can improve.

 Things You Can A/B Test in Newsletters

What can you actually test in your newsletters? There are many possibilities! Here are some key things to think about:

 Subject Lines

The subject line is the first thing people see, so it’s very important in getting them to open your email. Testing different subject lines can really change your open rates.

Here are some ideas for different subject lines:

  • Length: Try shorter vs. longer subject lines.
  • Personalization: Include the person’s name or other personal information.
  • Urgency: Create a sense of urgency with phrases like “Limited Time Only” or “Don’t Wait.”
  • Intrigue: Ask a question or make people curious to get them to open the email.
  • Emojis: Use emojis to make your subject lines more eye-catching.

 Email Content

The content of your email is just as important as the subject line. It needs to be interesting, useful, and persuasive to get people to take action.

Here are some content elements you can test:

  • Headlines: Try different headlines to see which ones grab attention and make people want to read more.
  • Body Copy: Test different tones, styles, and lengths of your email text.
  • Images: Use different images or videos to see which ones your audience likes best.
  • Calls to Action (CTAs): Try different CTA buttons, text, and where you put them in the email.

 Design and Layout

How your newsletter looks can also affect how well it works. A good design is visually appealing and easy to read. This can improve the user experience and engagement.

Here are some design and layout elements to test:

  • Templates: Try different email templates to see which ones work best.
  • Colors: Use different color schemes to see which ones look the best.
  • Layout: Test different layouts, like one column vs. multiple columns.
  • Mobile Optimization: Make sure your emails look good on phones and test different mobile layouts.

 Send Time and Frequency

When and how often you send emails can also affect how well they do. Sending emails at the right time can increase opens and engagement.

Here are some send time and frequency elements to test:

  • Send Time: Try sending emails at different times of day or days of the week.
  • Frequency: Test sending emails more or less often to find the right balance for your audience.

 How to Do A/B Tests That Work

To do A/B tests effectively, you need a plan. Here’s a step-by-step guide:

 Set Clear Goals

Before you start testing, it’s important to set clear goals. What do you want to achieve with your test? Having specific, measurable goals will help you stay focused and track your progress.

Here are some examples of clear goals:

  • Increase email open rate by 5%
  • Improve click-through rate on a specific CTA by 10%
  • Increase conversion rate for a product promotion by 15%

 Create Variations

Once you have your goals, it’s time to create your variations. Remember to test only one thing at a time. This will help you know exactly what caused any changes in performance.

Here are some tips for creating good variations:

  • Start with your control (version A): This is your original email.
  • Change only one thing for your variation (version B): This could be a different subject line, CTA, image, etc.
  • Keep everything else the same: This makes sure you’re only testing the one change.

 Set Up Your Test

Next, you need to set up your A/B test in your email marketing tool. This usually means dividing your audience into two random groups:

  • Group A: Gets version A (the original).
  • Group B: Gets version B (the change).

It’s important to divide your audience randomly to avoid bias. You also need to choose the right sample size and test duration. Your sample size should be big enough to give you results that you can trust. Your test should run long enough to gather enough data.

Send by Elementor has tools for audience segmentation. These can help you target your A/B tests to specific groups of subscribers.

 Analyze Results

Once your test is done, it’s time to analyze the results. Your email marketing tool will give you data on how each version performed. Pay attention to the key metrics you’re tracking, like open rates, click-through rates, and conversion rates.

It’s important to find out if your results are statistically significant. This means that the difference in performance between the two versions is likely due to the change you made, not just chance. Your email marketing tool may have features to help you with this.

When you analyze your results, ask yourself these questions:

  • Which version did better?
  • Is the difference in performance significant?
  • What can you learn from the results?

Use Send by Elementor’s analytics to track how your campaigns are doing and show your clients the value of your work.

 Make Changes and Keep Testing

If your variation (version B) did better than the original (version A), use the changes from version B in your future email campaigns. But A/B testing isn’t a one-time thing. It’s a process that never ends. Keep testing and improving your newsletters to get even better results.

Use what you learn from each test to plan your next tests. What new things should you test? How can you improve your emails even more?

 A/B Testing Best Practices for Newsletters

To get the most out of your A/B testing, follow these best practices:

 Start with a Hypothesis

Before you start testing, come up with a hypothesis. A hypothesis is a statement that you want to test. For example, your hypothesis might be: “Using a subject line with the person’s name will increase email open rates.”

Having a clear hypothesis will help you stay focused and make sure your tests have a purpose.

 Test Big Changes

Focus on testing changes that are likely to make a noticeable difference. Small changes might not change much. For example, changing a button color from light gray to dark gray might not do much. But changing the button text from “Submit” to “Get Your Free Guide” could have a bigger impact.

 Segment Your Audience

Dividing your audience into segments can help you get more accurate results. For example, you might want to test different subject lines for different age groups or locations. Send by Elementor’s segmentation features make this easy.

 Keep Records of Your Tests

Keep track of all your A/B tests and their results. This will help you see your progress and find patterns over time. Keeping records will also help you avoid repeating the same tests later.

 Be Patient

A/B testing takes time. Don’t expect to see big changes right away. It’s a process of testing and improving over time.
