My suggestion is to do this with an email signup form, Mailchimp double-opt in and auto responder emails. You can use WordPress, another type of CMS Dropbox, or just a regular website.
Once they have confirmed their email, in the final thank you response email you will send them a link to the file and a password. You can change that password however infrequently you choose – password protected pages aren’t indexed, and people who are going to share the material will do so as soon as they have it anyway.
