How to Run Experiments

Experiments are an advanced feature available within Sendlane that you can use to run split tests on campaigns!

With Experiments you're able to create a message and test multiple versions in a small portion of your audience to see which one performs best. Once the winner is determined, that version will be sent to the rest of your contacts! Experiments allow you to test contact's response to different versions of messaging, showing you the email with the highest performance. 

Before Getting Started

In order to set up different Experiments, you should first understand how to build a campaign

Running Experiments

  1. Click New Campaign inside of the Campaigns tab
  2. Enter a name for your campaign and check the Experiments box 

  3. In the Experiments Settings section, you'll set basic parameters for your test
    • Components - The specific features of the email you'd like to test (subject line, preheader text or content)
    • Test Audience - The percentage of contacts you would like to release the Experiment to
    • Winning Version - Decide which metric to focus on (click rate, open rate or revenue) and how long to run the test for
  4. Click Next: Content to finalize your basic settings and move on
  5. Begin building your first email (Test A) by filling in any content sections you'd like to have across all versions (those items will be up top) and the test versions (towards the bottom)
  6. Once you've finished test A, either click Add new test to start from scratch or Copy A to duplicate your original version
    Please Note

    You can create up to 4 different test versions within each experiment, and select any combination of components to test.

  7. Repeat steps 5 and 6 until you've created the desired amount of test email versions (A-D) for your Experiment

  8. Click Next: Audience to continue through the campaign creation process, setting your audience, and scheduling your message!

Next Steps

While your campaign is sending and the experiment is running, the campaign status will be  Experimenting. Plus, for any campaigns sent using the Experiments feature, you'll see the experiments icon next to the status:

Once the experiment has finished and the campaign has been sent to all of your contacts, you can see the winning test version (and a summary of the experiment details) within your campaign reporting.
