SleekView for Post SMTP
Post SMTP captures every send and every failure across Gmail, Microsoft 365, Brevo, or any SMTP host. SleekView turns wp_post_smtp_logs into the workable view your ops team can actually live in.

Post SMTP routes the mail and stores the proof. The default log is the bottleneck.
Post SMTP runs 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 full 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 the badges are not sortable across columns and there is no saved failed-only view for daily ops triage. SleekView opens the same table with sort and filter on every column, including mailer and retry count. A pivot by mailer over the last 30 days tells you whether to migrate to a different SMTP or stay where you are.
Bulk resend turns recovery into a single click. After the provider outage clears, filter to failed since the outage start, select all rows, and resend through Post SMTP's own retry logic. Customer emails land before breakfast instead of trickling through manual one-row resends. The mobile app keeps doing what it does. SleekView is the WP Admin layer.

Features
What SleekView gives you for Post SMTP
Cross-mailer comparison
Group by mailer to see which provider has the best delivered rate this month before committing to a single SMTP for the next year of transactional mail.
Bulk resend
When a provider outage clears, select every failed row from the window and resend in a single batch through Post SMTP's own retry logic and gateway.
Chronic-failure detection
Sort by retry count descending and the addresses bouncing on every send float to the top, ready for cleanup before they hurt sender reputation.
Audience
What ops teams use it for
Outage recovery
Provider went down at 2am. Filter to failed since 2am, hit bulk resend, and every customer email lands before breakfast without manual one-row work.
Mailer benchmarking
A pivot by mailer over 30 days tells you whether to migrate to a different SMTP, renegotiate with the current one, or stay put with confidence.
Support escalations
Customer claims an email never arrived. Search the recipient, see the mailer response and timestamp, reply with hard data instead of guesses.
The bigger picture
Why mailer benchmarking changes deliverability decisions
Most WordPress sites end up running Post SMTP through a single mailer because the setup wizard makes that the easy path. The result is that deliverability decisions get made on vendor marketing copy rather than on actual delivery data from your own traffic. Post SMTP is already capturing every send response, including the mailer-specific status code and retry count.
The data exists. What is missing is the workable view that lets ops compare mailers over time. A pivot by mailer over the last 30 days reveals which provider quietly bounces three percent of your transactional emails to a specific TLD, which one throttles you on Black Friday, and which one stays solid through a holiday weekend.
That is the data that should drive the migration decision, not the vendor's case study deck. The same view also supports outage triage in real time. When the provider's status page is still green but your failed-only view is filling up, you have ground truth ten or fifteen minutes ahead of the public incident report.
The combination of historical benchmarking and real-time triage turns Post SMTP from a delivery utility into a real ops surface, with no extra logging code and no extra moving parts.
Questions
Common questions about SleekView for Post SMTP
Yes. SleekView reads the same wp_post_smtp_logs table both the free and Pro versions populate. Every column the free plugin captures becomes available, including receiver, subject, mailer, status, retries, the full response, and the timestamp. Pro features that add extra fields surface automatically once they exist in the table.
 No. SleekView reads the log and triggers Post SMTP's own resend logic when you click resend, so retries follow the plugin's rules and the configured gateway. The view never bypasses the plugin's send pipeline. Failed sends that get retried through bulk resend behave exactly as they would if you clicked resend on each row individually.
 Yes. The full mailer response is one click away from the row in the drawer view, and you can search inside it. This matters when a provider returns a specific reason code that explains the failure, or when you need to copy a response into a support ticket with the mailer to escalate a deliverability issue that is not your fault to fix.
 SleekView is a WP Admin view. The Post SMTP mobile app keeps doing what it does, alerting you to failures from your phone. The data both tools share remains in sync because both read from the same wp_post_smtp_logs table. Acknowledging a failure in one does not prevent you from triaging it in the other.
 Yes. Each site has its own wp_post_smtp_logs table and SleekView opens them per site without cross-site mixing. A network admin can switch between sites to see each site's mail log. This matches Post SMTP's own per-site logging model and keeps deliverability data properly scoped to the site that produced it.
 Yes. SleekView checks WordPress capabilities, so you can scope read or edit access exactly where you want it. Ops gets the failed-only view with bulk resend. Support gets read access for lookups. Developers get the full response view for debugging. Each role sees only what it needs without giving everyone full site admin.
 The plugin has a configurable retention setting that defaults to a number of days, after which logs are pruned. SleekView reflects whatever is in the table, so the retention setting still controls history depth. If you need longer history for audit purposes, increase the retention in Post SMTP settings, and SleekView surfaces the longer history immediately.
 SleekView row actions can call any registered WordPress hook, so if Post SMTP exposes a test-send action you can wire it up. The action then runs through Post SMTP's own send pipeline using the configured mailer, exactly as the plugin's built-in test send does. The result lands as a new row in the log immediately, ready for inspection.
