WP Mail Bank routes outbound mail through a configured SMTP host with optional fallback chains. Configuration sits in wp_options under wp_mail_bank_options including host, port, encryption, from-name, and reply-to. When the bundled logger is on, per-send rows land in wp_mail_bank_log with recipient, subject, status, SMTP response, and timestamp.

The default admin separates routing settings, the test-mail tool, and the log viewer into three tabs. There is no saved-view layer, no per-source filter, no bulk retry. Auditing why a specific recipient never received a notification means reading the log line-by-line and copying SMTP codes into a search.

SleekView reads the log table directly, exposes routing rules as a row-level configuration view, and joins recipient to source plugin where the field is populated. Bulk retries flow through the plugin's own send handler so wp_mail filters fire.

Sites that route outbound mail through a primary plus fallback chain gain reliability at the cost of observability: each send may have taken the primary, the fallback, or both. WP Mail Bank's log captures that data in wp_mail_bank_log, but its own viewer is a flat list. There is no saved-view layer, no route-aware filter, no bulk retry.

Operators end up scrolling through pages of rows when a fallback-used spike or a 5xx run actually needs to surface as a single saved cohort. SleekView reads the same table and exposes route, status, and SMTP code together. Support can answer per-recipient questions in one screen.

Site admins can edit the routing chain as a row-level configuration. Ops can watch fallback-used counts climb as the primary host starts to degrade, a leading indicator that beats waiting for complaints. The plugin's own retention, retry, and validation logic still owns those concerns; SleekView simply gives the existing data the workspace it has lacked.
