This plugin is really neat. It’s not as much as a security plugin but it will help you protect your content until the reader will subscribe to your email campaign, which is really great.
Opt-In Content Locker is a plugin that allows you to lock important content on your WordPress website and display it for subscribed users only. All you need to do is to wrap protected content with shortcodes [optinlocker]...[/optinlocker].
If people want to view this content, they must submit their name/e-mail. After submission, all the locked content becomes visible.
Very simple workflow. All submitted data is saved in a database or/and can be re-submitted to MailChimp, AWeber, GetResponse, iContact, Campaign Monitor, Mad Mimi, Benchmark, Sendy and MyMail. All saved data can be exported as CSV-file to be used with any other newsletter systems.
Opt-In Content Locker is a perfect way to extend the functionality of your website.
