No. The Mailchimp, FeedBurner, or AWeber dashboard still owns deliverability, opens, and clicks since sends happen there. SleekView Charts adds the WordPress-side dashboard for signups, source pages, and ESP distribution that WP Subscribe does not assemble in its own admin.

It works best when submissions are logged. If only the widget options exist locally, SleekView can still chart configuration (which ESPs are in use, list IDs, instance counts) but trend and per-page charts require a submission log. Most companion code or themes provide one.

Yes. Resolve source page_id to its terms via the wp_term_relationships join, then group by category slug. The dashboard renders a horizontal Bar with categories ranked by signups for content-strategy reviews.

Yes. Dashboard-level filters apply to every chart card. Filter to just Mailchimp signups or just AWeber and every card scopes accordingly, so per-ESP dashboards become one-click switches rather than per-card reconfiguration.

Yes. Aggregations run on indexed columns and avoid full table scans. Sites with hundreds of thousands of submissions render charts in seconds because the Charts engine uses pagination and indexed joins rather than scanning meta.

Yes. Each chart card exposes its underlying row set, which exports to CSV with active filters applied. The export feeds board reports, attribution tooling, and ad platforms without spreadsheet round-trips.

Yes. Each subsite has its own WP Subscribe options and submission log, and SleekView Charts reads the current subsite by default. Network-wide dashboards can be configured explicitly when reporting spans multiple subsites.

It still works. SleekView reads every instance from the widget options array and treats each as a row with a placement label. A single Bar card ranks instances side by side, exposing which sidebar position converts best at a glance.
