Post SMTP routes WordPress emails through Gmail, Microsoft 365, Brevo, Mailgun, SendGrid, Amazon SES, or any SMTP host you wire up, and writes every send into wp_post_smtp_logs with mailer, status, retry count, recipient, subject, and the mailer response. When deliverability hiccups, this is the data that tells you what is happening, often hours before the provider's status page admits the issue.

The default Post SMTP log shows status badges per row but no sortable dashboard. SleekView Charts reads the same table and surfaces the answers as cards. A Number on total sends. A Pie on mailer so route share is one glance. A Bar on retries so messages stuck in retry loops rank themselves. An Area on sent_at so an outage shows up against the calendar.

Bulk resend turns recovery into a single click from the matching Table view. After the provider outage clears, filter to failed-since-outage, select all rows, and resend through Post SMTP's own retry logic. The mobile app keeps doing what it does. SleekView is the WP Admin analytics and ops layer.

Post SMTP is often the only honest source of truth for outbound mail health on a WordPress site. The log captures route, status, retry count, and timestamp before anything else upstream catches an issue. SleekView Charts turns wp_post_smtp_logs into a dashboard with KPI numbers, mailer share, retry distribution, and trend, so ops can detect SMTP outages hours before the provider admits them and decide on route migrations with data instead of vibes.

The plugin keeps owning the SMTP routing. SleekView owns the analytics on top.
