Documentation

Plan Campaigns skill: CX Enterprise Coworker for Marketo Engage can now turn a campaign brief into a complete Marketo Engage program setup document. The document includes folder structure, smart campaigns, email configurations, tokens, and a QA checklist. This helps teams launch campaigns faster and standardize program setup. The skill is configurable via markdown.

Coming soon

Callable Agents: Create AI agents that run as a flow step in your smart campaigns and act on a lead record based on instructions you write in plain language. For example, an agent can normalize a lead's data or flag likely bots, then write the result back to fields on the lead. This brings judgment-based lead processing into your campaigns without custom code.

Coming soon

Clone to This Program/Folder: Cloning operations across Marketo Engage now consistently offer a "This Folder" or "This Program" option as a first choice when choosing the destination of the cloned asset. Choosing this option clones the asset to the parent program or folder of the current asset.

Coming soon

Instant alert on CRM sync: Enabling or disabling the native CRM sync for an environment now triggers a notification to users who are subscribed to the CRM notification channel.
