A/B Testing

Test different email variants to optimize open rates and conversions. The ab_test node type selects a variant by weighted random and stores the result on the enrollment.

How It Works

• Add an ab_test node with a variants array.
• Each variant has an id, templateId, and weight (relative, not percentage).
• At runtime, a variant is selected via weighted random. The template is sent and the variantId is stored on the enrollment.
• Query enrollments to calculate per-variant conversion rates.

{
  id: "n1",
  type: "ab_test",
  label: "Subject line test",
  variants: [
    { id: "short", templateId: "tmpl_short_subject", weight: 50 },
    { id: "long", templateId: "tmpl_long_subject", weight: 50 }
  ],
  nextNodeId: "n2"
}
