This plugin helps you tailor your notifications and alerts to the users interests. 
Automatically send a new post notification or email digest to all users subscribed to one of its categories, tags, or authors. 
For each post published, you might not want to send an email to your entire email list. 
This plugin will help you segment subscribers to send targeted emails. 
Send an email grouping together the latest blog posts relevant to users preferences. 
Store locally and send with the provider of your choice, or store and send with mailchimp.
Grow your mailing list and collect subscribers interests : Insert a subscription and category/tag selection form anywhere on your website. 
Send highly relevant emails automatically : Notify users when a result for one of their searches, or a post under a category or they’ve marked as relevant to their interests, has been added. 
Decide how often you want to send an email digest of published posts : Email frequency matters. You can group together a few blog posts to send at your desired frequency.
<h3>Examples</h3>
You can add a subscription form offering multiple choice categories anywhere you want, if you want to segment your users by post category or tag of interest. 
Or, for your signed up users, you can track their recent search queries to be able to notify them if a new post matching one of them has been published.

This plugin is designed for administrators to share the task of moderating comments and publishing posts marked as “Pending Review”. It is NOT designed to notify non-admin subscribers of new comments or posts.
The plugin adds checkboxes to the WordPress profile page, allowing you to setup notifications for these events:
<ul>
<li>a comment is added</li>
<li>a comment is held pending approval</li>
<li>a post is pending review, </li>
<li>a post is published</li>
</ul>
If you have permission to edit other users, you can also setup notifications for them… so when you go on holiday, you can set a colleague to receive the comment notifications while you’re away.
Users can only receive notifications for comments if they have the authority to moderate comments, and can only receive post notifications if they have the authority to publish posts.
