YITH WooCommerce Cart Messages writes every cart upsell message as a yith_cart_message custom post in wp_posts. Each message carries a trigger type (Referer, Minimum Amount, Deadline, Product in Cart, Category in Cart) and a payload, persisted under _ywcm_message_* postmeta keys including _ywcm_message_type, _ywcm_message_text, and the trigger-specific value. The default admin lists messages one at a time and exposes no roll-up of the message catalog.

SleekView Charts reads the same wp_posts and wp_postmeta rows. A Number card counts active cart messages across the catalog. A Donut splits messages by trigger type so the marketing team sees whether referer-based, threshold-based, or category-based triggers dominate. A Bar ranks the products and categories most frequently used as triggers, and an Area chart trends message creation over time so the catalog growth story becomes obvious.

The dashboard does not replace the YITH editor. Marketing still drafts messages in the YITH UI. SleekView Charts adds the missing inventory layer: which messages exist, which triggers they use, which products they target, and when the catalog grew. Stores running dozens of cart messages across seasonal campaigns and evergreen offers replace mental bookkeeping with a single dashboard.

Cart upsell messages accumulate the way email automations do: one well-intentioned campaign at a time, each with its own trigger and its own product targeting. YITH writes every message cleanly to wp_posts and persists its trigger in wp_postmeta under predictable keys. The data shape is excellent.

The default admin presents the list chronologically and exposes none of the inventory questions a marketing team eventually needs to answer. Which trigger types do we lean on most? Which products carry too much upsell weight? When did the catalog grow versus shrink? Stores running seasonal campaigns and evergreen offers in parallel build mental models that the chart layer can actually verify. SleekView Charts reads the YITH custom post type and the trigger postmeta keys and renders the four cards that turn the message catalog into a measurable system.

Active messages as a Number, trigger types as a Donut, top triggering products as a Bar, and creation-over-time as an Area trend. The plugin already collects the data. The dashboard makes the strategy visible.
