Your form can say “Message Sent” while the notification email still has problems.
This plugin keeps an admin-only backup of supported form submissions on your own site, and shows WordPress mail-processing health in one dashboard — fully self-hosted, nothing sent off-site.
Highlights
wp_mail() test.Supported form sources
WooCommerce email monitoring
WooCommerce transactional email uses the WordPress mail pipeline. This plugin therefore records WordPress wp_mail() success/failure events used by WooCommerce and other plugins when mail-event logging is enabled.
Important email status note
WordPress documents that the wp_mail_succeeded action only means PHPMailer processed the request without an error. It does not guarantee that the recipient received the message in their inbox. This plugin intentionally labels this state Sent, not Delivered.
Security and privacy
Lead data is kept in your own site’s database — it never leaves your server. Common password, payment-card, nonce, CAPTCHA and security-token fields are intentionally omitted. Email bodies are not stored in the mail log.
After activation, review Settings > Privacy if your site needs to disclose local form-submission storage.
