Download Monitor is a download counter that will provide you with detailed statistics of any file downloads on your web site. It also optionally comes with autoresponders to send email to visitors who downloaded files. You can also choose to record additional information from visitors downloading files which you can view at any time. Download Monitor Pro also comes with the ability where visitors can subscribe to a mailing list (when downloading a file). You can then send email with Download Monitor to visitors who downloaded files and have chosen to subscribe to the mailing list.
Lets say you offer software downloads and you would like to know how many times each file has been downloaded. Download Monitor Pro would have recorded all download counts and email addresses (optional) of visitors who would like to be informed of updates or new software releases. You can then use Download Monitor Pro to email visitors who downloaded the file about upgrades or updates. You could also let them subscribe to your newsletter for example and then mail subscribers (visitors who downloaded files) directly from Download Monitor Pro.
