Since Magento 1.9, all transactional emails were being queue and sent with cronjob. That is really good, but what I am concern here is about is there anyway to manage them.
How and where Magento save them? I think core_email_queue serve for this one.
I tried to find which part/modules in Magento core handle this job (queueing email and setup cronjob to send). But unfortunately, I can't.
Long-live bloody poor Magento documentation!
Any help will be appreciated. Thank.
