Create a New Campaign

Navigate to the "Campaigns" tab in Customer.io and select "Create a New Campaign."


Fill in Campaign Details

Provide a name and a description for your campaign. The name should be unique and the description should clearly explain the goal of the campaign.

On the next page, you'll define your campaign's workflow. Drag and drop 'Email' from the left menu onto the workflow canvas.


Select “Turn into A/B Test” Option

While setting up the campaign, opt for the A/B test feature.


Design Your Variant Emails

Create two different message designs or content for your A/B test.


Personalize Your Message

Use Customer.io's Liquid templating to insert personalized elements such as {{customer.first_name}} or {{customer.last_purchase}}.
