What It Does

The GD Mail Queue plugin adds a mail queue system that intercepts all emails sent through the wp_mail function. It processes emails based on predefined rules, allowing each recipient to receive their email individually. The plugin can convert plain text emails into HTML format and provides options to customize the email templates.

The mailer component of the plugin controls the entire process, including intercepting wp_mail calls, wrapping emails in HTML, and managing the queue based on the number of recipients. This ensures that all WordPress system emails, such as registration and password resets, are sent as HTML.

The queue operates through CRON jobs, allowing you to configure how many emails are sent in a batch while preventing PHP timeout issues. It uses PHPMailer for sending emails, with additional options for customizing the sender details and using SMTP.

The plugin also features an advanced email logging system, storing relevant data for each email, including attachments. Users can view logs, retry sending failed emails, and access detailed previews of sent emails. Security features include sanitizing email content to strip malicious elements.

GD Mail Queue Pro offers additional features such as REST API based email sending engines, integration with third-party SMTP services, and enhanced logging and dashboard functionalities. The plugin is designed to work seamlessly with the default WordPress wp_mail function and is not compatible with plugins that replace it.
