This add-on will cycle through orders on a regular time interval and generate tickets and send the email for those orders where the order has been paid and tickets do not exist. Please see our documentation for usage warnings. https://wpraffle.com/docs/raffle-ticket-cron/basic-instructions/
This should only be used and setting should be set based on server capacity. If you have inefficient or cheap shared hosting and you set it to run every few seconds – it can create significant server load for sites with large order quantities. If you have a raffle running now and have a lot of orders – be aware – this will send emails from WooCommerce for all the orders that get adjusted. That is a function of WooCommerce. This plugin will use the WooCommerce hook to create the trigger and filter of changing the order status per the woo guidelines. That will tell our raffle plugin that the order is paid and the tickets get generated and email is sent. Please contact us if you have questions before purchasing.
