I'm searching for ways to grant access to download a file, only after subscibe to a newsletter. What are the best practices or your experiences to do solve this task?
It's about a Wordpress website. So far I did this steps:
A Popup (boxzilla) with the newsletter subscription (Mailchimp) appears after user clicks a button
Now the user have to fill out the email field.
The mailchimp registration will follow, after clicking submit
now I'm planning to write a script, so that the click also starts the download (jquery.onclick() ?)
But I want also to track, if a user filled out the email field or not. Everything possbile with little coding, but is that the best practice? I could see that kind of registration often on other sites. How they are doing that? Maybe there exists also a good plugin to handle all this stuff including tacking?
hanks in advance for your help
