How to Run A/B Tests in Email Marketing

Unlock the potential of your email marketing with A/B testing. Learn the rules, focus areas, and how to drive profitable growth.

A/B testing is a powerful tool in email marketing that can significantly improve your campaign's performance. It involves creating two variants of the same email and seeing which one resonates more with your audience. This process is simple yet effective, and with many email apps allowing you to set up these tests quickly, there's no reason not to be constantly A/B testing.

Not All A/B Tests Are Created Equal

While A/B testing is straightforward, not all tests yield equally valuable results. The key is to focus on elements that have a significant impact on your email's performance. Small changes, such as using a personalized sender name instead of a generic one, can make a big difference. However, it's crucial to test only one element at a time to accurately attribute any performance differences to the change made.

Email Marketing Rules for A/B Testing

When conducting A/B tests, it's essential to adhere to email marketing laws and regulations. For instance, the CAN-SPAM Act in the US sets rules for commercial email, including requirements for commercial messages and penalties for violations. Compliance with these laws not only keeps your business on the right side of the law but also helps maintain good email deliverability rates and improve your overall email marketing strategy.

Test the Big 3

1. Signup Form Tests

A/B testing your signup forms can help optimize the user experience and increase conversions. You can test various elements, such as the form layout, field labels, and call-to-action text. Klaviyo, for instance, provides features to A/B test a sign-up form.

2. Welcome Flow Tests

The welcome email series is another critical area to test. This is the first interaction a new subscriber has with your brand, so it's crucial to make a good impression. You can test different welcome messages, content layouts, and calls-to-action to see what resonates best with your audience.

3. Abandoned Cart Flow Tests

Abandoned cart emails are a powerful tool to recover lost sales. A/B testing these emails can help you find the most effective way to encourage customers to complete their purchase. You can test different subject lines, email content, and discount offers to see what works best.

Conclusion: Test What Matters

A/B testing is a continuous process of learning and improving. By focusing on the elements that matter most to your email performance, you can make meaningful improvements to your campaigns. Remember, the goal is not just to find what works best now, but to gain insights that will inform your future strategies.
