Mailster keeps subscribers in wp_mailster_subscribers with sent, opens, clicks, and bounce counters aggregated per recipient. Lists, actions, and forms each live in their own tables, which gives Mailster a CRM-style schema underneath its sender. The default admin presents the data through subscriber and campaign screens, with the deeper aggregates clicks-deep.

SleekView Charts reads the schema and renders chart cards on one dashboard: Number for total subscribed, Donut for status mix, Bar for engagement-per-list, Area for daily new subscribers. The same custom subscriber fields Mailster supports become chart groupBy dimensions, so personalization data drives reporting as well as sending.

The dashboard refreshes as Mailster writes new sends and events, so the daily list-health view and the pre-send segment check both work off the same surface without manual rebuilds.

Mailster has the schema for serious reporting (subscribers with per-recipient stats, list assignments, custom fields, action history), but the default admin presents the data through narrow screens that make weekly synthesis a tab-hopping exercise. SleekView Charts treats the schema as what it is: a CRM-style data model that benefits from a fast dashboard combining Donut, Bar, and Area cards on one surface. The email marketer building the next campaign sees the segment health in seconds.

The growth lead spots bounce-class trends before they tank deliverability. The support team answers tickets from the dashboard rather than per-row lookups. Mailster keeps doing what it does well; the people running campaigns get a one-screen reporting layer that matches how they think.
