hello my events site sells, I'm using node uc checkout for the sale of the events, but I want to send a reminder email as type 4 hours before the event begins. the truth and I searched the site and have not found something similar, is the first time I use ubercart.
Anyone know how to send an email 4 hours before the event begins?
It is important to note that the date selected by the user through a datetime field (this is possible because node checkout)
please any help is good
Thank you very much
