Automatically Notifying Customers of Out of Stock / Incomplete Orders

[fut]

As time goes by, the amount of orders that remain in my "Not In Stock" status build up. Once an order I receive is deemed out of stock, I send an e-mail to the buyer via the Order's page. Often, the buyer will not reply to the e-mail, or forget, for whatever reason.

 

I'd like for my system to send these e-mails automatically after I do it the first time. Simply put, all the orders that are in my "Not In Stock" or "Incomplete" status should be automatically updated, once a day, to send the same e-mail I sent earlier. This way, the buyer continually receives this important notification e-mail and has a higher chance of giving a response.

 

Is there a contribution for this, or some code I can use to achieve what I am looking for?

 

Thanks!

Can anyone help me? Is this even possible?
