Downloadable Product with Updates??

I have several different downloadable products (zipped Excel files) and I will be updating the files every couple of months. I would like to send an email notifying prior customers that their file has been updated and reactivate the download links.

First of all, is this possible?

I don't see a way to send emails to customers based on the product they purchased. Also, I would need to be able to reactivate download links.

Maybe I could send an email blast to all customers with a generic message asking them to login to download the updates. The main question then would be how to reactivate all download links in a somewhat efficient manner.

If anyone has dealt with downloadable products and updates I would greatly appreciate your input.

Thanks!

Are you planning to use the same filename or a new filename for these updates?

I would prefer to use the same file name. The updated file would be the file that new purchasers would get as well. In terms of work, changing the file name would mean changing each product (40 or so) in the product attributes right?

Personally, I would get some custom code written for this ...

If you want to update all Orders with 1 upgraded filename, then it could go through the steps that you would have to take of finding all of the orders_products_download records and update them based on orders_id and reset them based on individual Order Dates ...

You could also do this manually by doing a search on the Customer ... Orders ... for the Product Name and then edit each one ...
