How to Use the Randomizer (A/B Test) for SMS

Learn how to run split tests within SMS flows.

Split testing, also known as A/B testing, is a crucial component of SMS marketing flows that involves experimenting with different variations of messages to identify the most effective approach.

  • you can send out multiple versions of a message to different segments of your audience to determine which one yields the best results in terms of engagement, conversion, ROI, and other key performance indicators.
  • By analyzing the results of these tests, you can refine and optimize your SMS campaigns, ensuring that you deliver the most impactful and relevant messages to your audiences.

How to Use Split Tests within an SMS Flow:

  1. In your chosen SMS Flow, click on the + icon and select “Randomizer”
    RD 1

  2. Click on the “Randomizer” block to open the editor on the left-hand side of the screen

    • here you can change the percentage of audiences receiving the message or add more splits
  3. If you choose to add a third split (or more), but the sum of your percentages no longer adds up to 100%, you will receive an error message
    RD 3

  4. To rectify this you can: a. manually enter amounts adding up to 100% b. click “split traffic evenly” - it will then automatically be split into equal segments adding up to 100%

    RD 5

  5. Once you have created your randomizer split, add different messages to each percentage. You can experiment in many ways, including:

    1. sending out different discount values or different types of deals (percentage off, dollar value off, free gift, etc.) to see which is more successful

    2. experiment with different wording

    3. Include specific conditions or delays before one of the messages to test different days/times/specific product deals (see more ideas below)

Tips & Tricks

Here are a few things you can test with split tests:

  1. discounts
    • use different values of discounts/offers to learn what people want ie. 10% vs 15%, 10% vs $10, or even 10% vs a free gift
  2. message content
    • change the language of the messages to determine what resonates better with your audiences
  3. timing & delays
    • try sending messages out a different times of the day or on different days to test when your audiences are likely to buy
  4. calls-to-action
    • try various calls to action, such as visiting a specific page for a discount or redirecting to customer reviews to see what hooks your audiences
  5. audiences
    • send messages to different audiences, testing out which content works for each one
