WP Maintenance Mode (formerly by Designmodo, now Frontity) hides the site behind a holding page while collecting emails from visitors who tap the subscribe form. The emails are written to a serialized array under wpmm_subscribers in wp_options, with no admin screen beyond a CSV export and a count.

SleekView Charts reads that same option, parses the timestamped entries, and renders the list as live chart cards. Total subscribers in the current window become a Number KPI. Sign-ups per day become an Area trend. Domain breakdown of opt-ins (gmail.com vs company.com) becomes a Bar chart that tells you whether the lockdown caught new prospects or known users coming back to check in.

The dashboard updates straight from the option, so every save in WP Maintenance Mode refreshes the chart cards. Maintenance windows themselves can be charted from the wpmm_settings option that stores the activation timestamp, giving operations a clear record of how often the site was locked and for how long. No CSV, no spreadsheet, no manual count of who signed up while the site was offline.

WP Maintenance Mode has one of the highest-converting holding screens in the WordPress ecosystem because everyone with an email field on a lockdown page gets a few extra opt-ins. The plugin captures that data, stores it, and stops there. Counting subscribers happens in WP Admin.

Trending sign-ups requires CSV gymnastics. Comparing two lockdowns means manually filtering by date in Excel. None of that work is hard, but none of it gets done because the friction kills the habit.

SleekView Charts reads the same wpmm_subscribers option the plugin already maintains and turns each row into something a dashboard can render. Total subs in the current window, daily trend, domain split, and activation overlap all become cards on one screen. Marketing checks the dashboard, ops checks the dashboard, agencies show the dashboard to clients, and the CSV stays in the export folder where it belongs.
