The addons are made for the GD Mail Queue Pro, and there are no plans to have addons supported in Lite/Free version.
Most email sending plugins start by replacing wp_mail() function in WordPress making it hard for other plugins to do anything related to email sending. GD Mail Queue plugin doesn’t replace this function (or any other WordPress function), and it is relying on that core function to intercept and determine if the email should be turned in HTML or added to the queue.
But, GD Mail Queue has support for SMTP email sending, and you can add your SMTP server information for plugin to use for all emails and/or queue emails. If you need to use REST API for email sending or you want to use predefined SMTP sending services through PHPMailer, GD Mail Queue Pro supports several popular email services using official REST API libraries and SMTP sending to.
All plugins that send emails to various services using REST API or some other API to connect to services, are always replace wp_mail() function making it impossible for my plugin to detect emails and work with them. Also, GD Mail Queue can’t use third-party plugins to send emails, because there is no universal interface for this that all plugins can implement and use.
If you use BuddyPress HTML emails feature, it will work as expected, and GD Mail Queue will handle these emails without turning them into HTML. You can also use an option in GD Mail Queue to force BuddyPress to send plain text emails and GD Mail Queue will turn them into HTML emails.
