Special Messages & Marketing Offers¶

Waulter can display special messages within the consent interaction — promotional offers, announcements, or value exchanges that appear alongside or after the consent decision. This turns the consent moment into a marketing touchpoint while remaining fully compliant.

What are special messages?¶

A special message is configurable content attached to a configuration that the SDK displays during or after the consent interaction. Instead of a plain consent banner, visitors see an additional message — an offer, announcement, or call-to-action.

Examples:

Configuring special messages¶

Special messages are configured in the Waulter dashboard as part of your website configuration.

Setup steps¶

1. Open your configuration in the Waulter dashboard.
2. Navigate to the Marketing Message section.
3. Enable the marketing message.
4. Enter your message content (supports HTML).
5. Optionally, set a Campaign ID to track this specific message.
6. Save the configuration.

Configuration options¶

Conditional display¶

Special messages can be made conditional by combining them with Scenarios. Create different configurations with different messages, then use scenario rules to target them:

See Scenario-Driven Engagement for detailed implementation patterns.

Tracking with the special_functions event¶

When a special message is displayed and the visitor makes a consent decision, the SDK fires a special_functions event via gtag:

gtag('event', 'special_functions', {
  type: 'message',
  consent_decision: 'allow',   // The visitor's consent decision
  metadata: {
    campaignID: 'summer-sale-2026'   // Your Campaign ID from the configuration
  }
});

Event fields¶

Tracking in GTM¶

To track special message engagement in Google Tag Manager:

1. Create a Custom Event trigger:

2. Event name: special_functions

3. Create a Data Layer Variable for the campaign ID:

4. Variable type: Data Layer Variable

5. Data Layer Variable Name: metadata.campaignID

6. Create a GA4 Event tag:

7. Event name: consent_marketing_message
8. Parameters: campaign_id = your Data Layer Variable

9. Trigger: the Custom Event trigger from step 1

10. Measure results:

11. Track impression-to-consent conversion rates per campaign
12. Compare consent rates between configurations with and without special messages
13. A/B test different messages using scenario rules with the mod operator
