Site popup

Hi! Does anyone know how to create a popup before entering a new page? For example, I want to share content on a page but only for those that enter their emails. Ideally, when someone clicks to go to the page to access the content, they'd be prompted to add their email, enter, and then access the content on the next page. Thank you! 

You mean popup will appears on specific page only?

It will always appears when users reload the page?

It will disappear forever if users entered their email?

Is that right?

@tuanphan The popup will appear only when users click a button to view the prompts on the next page. The popup will disappear for good when users enter the email, even if they reload the page. 

Essentially, I want to offer free content, so when a user clicks to access the free content on the next page, they need to enter the email in the popup before viewing the free content and the page loading. Once the email is entered, they are taken to the next page (free content) and they do not have to enter their email again for future use.
