Opt-In Downloads (formerly Subscribe & Download) is a plugin that allows you to distribute files via subscription. If people want to download something from your site or third party sites, they have to submit their contact information. Once submitted, you will receive a download link via email. Very simple workflow. All submitted data is stored in a database and/or can be sent to popular email marketing providers such as MailChimp, iContact, GetResponse, etc. All stored data can be exported as a CSV file and used with any other information system. Opt-In Downloads is the perfect way to extend the functionality of your website.
