In some cases, it’s necessary to provide a summary of each post in your primary RSS feed while still syndicating 
your content with full text to various parties. Dual RSS Feed Key allows you to enter a secret key to use with 
your RSS feed to display a full text version of a site’s feed to those who have the key.

Try it out on your free dummy site: Click here => <a href="https://tastewp.com/plugins/feedburner-alternative-and-rss-redirect" rel="nofollow ugc">https://tastewp.com/plugins/feedburner-alternative-and-rss-redirect</a>. 
(this trick works for all plugins in the WP repo – just replace “wordpress” with “tastewp” in the URL)
This plugin allows you to easily switch from Feedburner to the FREE (on the <a href="https://follow.it/features-and-pricing" rel="nofollow ugc">basic plan</a>) and better Feedburner alternative follow.it.
Read more why follow.it is the <a href="https://follow.it/?page=3" rel="nofollow ugc">better Feedburner alternative</a>.
The plugin is very easy to use:
<ul>
<li>Step 1: Download, install & activate it</li>
<li>Step 2: Click on “Apply redirect” for all feeds you want to redirect (most likely your main feed, as well as some comments & author feeds you may have)</li>
<li>Step 3: Connect it to a follow.it account to get access to your subscribers, see statistics etc. (see screenshots)</li>
</ul>
Once the redirect is active, your RSS-url will redirect to your new feed page where users can subscribe to your feed.
If you had former Feedburner subscribers, follow the steps as prompted in the plugin to move them over to your new feed (RSS as well as Email subscribers).
If something is not working in the Feedburner alternative plugin, please post a question in the support forum. Thank you!
