Step-by-Step Guide to Setting Up A/B Tests in Klaviyo

1. Create an A/B Test for Campaign Emails

Start by navigating to the Campaigns section in your Klaviyo dashboard:

Navigate to Campaigns > Create Campaign.
Name Your Campaign: In the sidebar, provide a descriptive name for your campaign.
Choose Email: Select the Email option and click Continue.
Select Recipients: Choose the lists or segments you want to target.
Click Next: Proceed to the next step.
Input Campaign Details: Enter the subject line, preview text, sender name, and sender email address.
Create Your First Email Version: Add your copy, images, and links to craft variation A.
Initiate A/B Test: Click Create A/B test above the subject line field. Klaviyo will automatically generate a second, identical version (variation B) of your campaign.

2. Configure Your Test Variations

Test Subject Lines with AI

For paid Klaviyo accounts, leverage AI to automatically generate subject line variations:

Create an Email Campaign: Follow the steps from the previous section.
Choose a Template: Edit the email content as desired.
Generate Variations: Under the Subject line field, select an option from the Generate a variation to A/B test section.
AI-Generated Options: Klaviyo will create two subject lines, such as personalized vs. non-personalized, short vs. long, or emoji vs. no emoji.

Test Content

To evaluate different message contents:

Select Test Content: Click Test content at the top of the page.
Edit Variation: Modify one aspect of the email, such as images or CTA buttons, ensuring only one variable is tested at a time.
Limit Variations: It’s recommended to test only two variations to maintain clarity in results.

Test Send Times

Determine the optimal time to send your emails:

Select Test Send Times: Click Test send times at the top of the page.
Maintain Consistency: Ensure both variations have identical content and subject lines.
Choose Timing: Experiment with different times, such as evening vs. morning, or leverage Smart Send Time for automated optimization.

3. Select a Test Strategy

Depending on your account size, Klaviyo offers different test strategies:

Winning Variation (Standard A/B Test): Determines the best-performing variation and sends it to the remaining recipients after the test period.
Personalized Variations: Uses AI to tailor variations to individual recipients based on their behavior and profile data, ensuring personalized engagement.

4. Configure A/B Test Settings

Customize your A/B test parameters to align with your campaign goals:

Choose Winning Metric: Select the primary metric to evaluate, such as open rate, click rate, or placed order rate.
Adjust Test Size and Duration: Use the slider to determine the percentage of recipients in the test pool and the length of the testing period.
Consider Apple Mail Privacy Protection (MPP): For accounts with high MPP usage, adjust your test size or create custom reports to account for inflated open rates.

5. Review and Launch Your A/B Test

Before launching, ensure all settings are correctly configured:

Review Settings: Double-check your variations, test strategy, and metrics.
Launch Campaign: Click Send to initiate the A/B test.
Monitor Progress: Track the performance of each variation in real-time through Klaviyo’s analytics dashboard.
