Creatives

Overview

A creative is a content variant that defines how a specific offer is rendered on a specific channel. Creatives contain the actual messaging — subject lines, headlines, body copy, images, and calls-to-action — along with personalization variables and A/B test configuration. Each creative links one offer to one channel, allowing the same offer to have different presentations across email, push, web, and other delivery mechanisms.

Content Object

The content object varies by template type, but common fields include:

{
  "subject": "You're pre-approved for our Premium Card",
  "headline": "Upgrade to 3x Rewards",
  "body": "Hi {{first_name}}, based on your spending patterns...",
  "imageUrl": "https://cdn.example.com/premium-card.png",
  "ctaText": "Apply Now",
  "ctaUrl": "https://example.com/apply?offer={{offer_id}}",
  "deepLink": "myapp://offers/premium-card"
}

Field	Description
`subject`	Email subject line or notification title
`headline`	Primary heading text
`body`	Main message body (supports `{{variable}}` placeholders)
`imageUrl`	URL to hero image or thumbnail
`ctaText`	Call-to-action button text
`ctaUrl`	Click-through destination URL
`deepLink`	Mobile app deep link URI

Personalization Variables

Personalization variables inject dynamic values into the content at delivery time:

{
  "personalization": [
    {
      "variable": "first_name",
      "source": "customer.first_name",
      "fallback": "Valued Customer"
    },
    {
      "variable": "offer_rate",
      "source": "computed.personalized_rate",
      "fallback": "competitive"
    },
    {
      "variable": "offer_id",
      "source": "offer.id",
      "fallback": ""
    }
  ]
}

Field	Description
`variable`	Placeholder name used in content (referenced as `{{variable}}`)
`source`	Data source path — `customer.`, `computed.`, `offer.`, or `attributes.`
`fallback`	Default value if the source is null or unavailable

Use computed.* sources to inject dynamic computed values like personalized rates or custom pricing into creative content.

A/B Test Variants

Creatives support A/B testing by assigning each creative a variant label and traffic weight:

Variant	Description
`control`	The baseline creative (existing or default content)
`variant_a`	First test variant
`variant_b`	Second test variant

Traffic is split according to the weight field on each creative. Weights are relative — if control has weight 50 and variant_a has weight 50, traffic is split 50/50.

[
  { "name": "Email v1 - Control", "abTestVariant": "control", "weight": 50 },
  { "name": "Email v1 - New CTA", "abTestVariant": "variant_a", "weight": 30 },
  { "name": "Email v1 - Short Copy", "abTestVariant": "variant_b", "weight": 20 }
]

A/B Variant Weight Resolution

At runtime, the decision engine normalizes variant weights to select which creative a customer sees:

Collection — All active creatives for the same offer + channel are grouped.
Normalization — Weights are summed and each creative’s probability is calculated as weight / totalWeight. For the example above: control = 50/100 (50%), variant_a = 30/100 (30%), variant_b = 20/100 (20%).
Selection — A deterministic hash of the customer ID is used to pick a variant, ensuring the same customer always sees the same creative across requests.
Fallback — If no abTestVariant is set, the creative is treated as a standalone (no A/B split). If all weights are 0, each creative receives equal probability.

A/B test results are analyzed in the Algorithms module under Experiments. KaireonAI calculates statistical significance using z-tests on conversion rates.

Constraints

Field	Type	Description
`frequencyCap`	number	Maximum total impressions of this creative per customer
`cooldownHours`	number	Minimum hours between consecutive impressions to the same customer

These creative-level constraints work alongside contact policies which apply broader rules across offers, channels, and categories. Once your creatives are configured, set up qualification rules to control which customers are eligible to see them.

Creating a Creative

Navigate to Creatives

Go to Studio > Creatives in the sidebar.

Click Create Creative

Click the + New Creative button.

Write content

Fill in the content fields: subject, headline, body, image URL, CTA text, and CTA URL. Use {{variable}} placeholders for dynamic content.

Configure personalization

Add personalization variables that map placeholders to data sources with fallback values.

Set A/B variant (optional)

If running an experiment, assign a variant role (control, variant_a, variant_b) and traffic weight.

Set constraints (optional)

Configure frequency cap and cooldown hours for this creative.

Save

Save the creative. It is available for use in Decision Flows immediately.
