User exit for sending mail to customers

Question

Hi all
I have a requirement where i need to trigger a mail to customer when the shipments are planned for the sales order.
I got a suggestion asking me to use user exits for this. I would like to know is there any user-exit for this.  I came to know a user-exit exists to trigger mail when a purchase oreder is released. Is there any user-exit for triggering mail to customers once the shipmetns are planned for a sales oreder.
