Email Signals for SFMC Journey Builder: How It Works

Wunderkind captures and processes on-site behavioral data to determine the highest-priority campaign a visitor is eligible for during a session. Starting with real-time event collection, each visit is evaluated against your active campaigns in priority order, triggering a single signal that reflects the visitor's highest-intent action. The criteria outlined below inform which signal is sent to Salesforce Marketing Cloud (SFMC), where the remainder of the campaign eligibility logic resides. 

• Prospect and Customer Status: Visitor status is checked against Wunderkind's internal database, which is populated with your historical customer file during onboarding and kept current with real-time conversion data captured on-site via the conversion pixel.
  • If you are an existing Wunderkind client migrating to Signals, your current prospect/customer status check will be preserved. For example, if prospect and customer status are currently determined via an API call to your ESP, that integration will remain in place.
  • This status is included in our signal payload as UserType
• Send Frequency and Campaign Limits: A 24-hour send limit is enforced at the campaign level, ensuring each campaign is only triggered once every 24 hours for a given user. As a result, a user may receive multiple signals within 24 hours, provided each is for a different campaign. 

  • Wunderkind-provided journeys include cross-campaign priority to determine which campaign is sent to the end user.

• Subscriber Status: Before a signal is triggered, a final subscriber status check is performed in Salesforce Marketing Cloud (SFMC) to suppress opted-out users. This prevents unnecessary journey entries and preserves overall journey performance.

  • If you are an existing Wunderkind client migrating to Signals, your current subscriber status check will be preserved. 

  • If you are a new client onboarding with Wunderkind Signals, A global opt-out check is performed in SFMC using a Subscriber Retrieve Request. If the returned record shows a subscriber status of Unsubscribed, the user will be suppressed from the journey.
