Kaiizen Mail Log

eMail Logs logs every email sent through wp_mail() — WordPress core, WooCommerce, Contact Form 7, WPForms, Gravity Forms, Fluent Forms, and any other plugin that uses the standard mailing API — into a dedicated, indexed database table (never wp_posts), so it stays fast even at hundreds of thousands or millions of logged emails.

Features

• Zero configuration — logging starts automatically on activation.
• Dedicated, indexed database table with a FULLTEXT search index.
• Fast, filterable, sortable admin log table with keyset (seek) pagination.
• Full email viewer: headers, HTML/plain text, attachments, SMTP response, source detection.
• Resend any logged email, with the option to edit recipients/subject/body first.
• CSV and JSON export, filtered or full.
• Optional SMTP delivery — send all WordPress email through any SMTP server (host, port, SSL/TLS, authentication, From email/name), with the password stored encrypted or set via the KAIIZENML_SMTP_PASSWORD constant.
• Send a test email from the admin, with a redacted SMTP conversation shown when something goes wrong.
• Automatic retention cleanup, configurable per site.
• REST API (kaiizenml/v1) and WP-CLI commands (wp kaiizenml list|view|delete|cleanup|export).
• No premium tier, no telemetry, no tracking, no ads, no upgrade nags.
