Comment Notifier

You may want to have a look to Comment Plus as well. Comment Plus is an evolution of Comment Notifier that includes Comment Image.

Comment Notifier leta readers to subscribe a post comment thread and receive an email each time other users add comments.

Keep discussions  on fire!

Comment Notifier is a very simple plugin to install and configure. Visitors will have a “subscribe” checkbox to be notified when new comments are added on a specific post. Hence, subscription is “post based”: users subscribed won’t notified of each comment!

Comment Notifier create his own table on database and manage the subscriptions in it.

Email sent can be freely composed in the configuration panel with simple tag to customize each email: subscriber name, post title, post permalink, author name, comment excerpt.

And if you have the extras installed, you can do much more!

The subscription checkbox can be added automatically by Comment Notifier. If you need a better control on the theme layout, you can add the checkbox by hand. The configuration panel has the instructions you need.

I’m using this plugin in all my blogs!


Comment Notifier can be greatly improved with some of extra features:

  • insertion of last blog post links
  • insertion of configurable random ads of affiliate link
  • insertion of related post list

The picture below shows one of my notification emails:


As you can see it contains a list of posts (may be too much, but it’s just an example to show how it works).

When the extras are installed you can use tags like “last_posts”, “related_posts” and “ads” in the email body. Those tags are configurabile in the admin panel, as viewable in the picture below.


Where is the advantage of those extras? Notifications are emails that users usually just scan to see if the comment is of interest and then delete them. Adding useful content to those emails can bring you more traffic or help to sell a little more via affiliate links.

Extra features are sold for a small price: 4.99 $. Read my general license and then you can buy it here (temporary not available, I’m sorry).

You have to install Comment Notifier before use the extra features and Other Posts (which is included).


Remember to ask you questions here.


Comment Notifier is available on WordPress Plugin Directory:

and can be update directly from your plugins panel.


Specific and more verbose release notes can be found in posts under the tag “comment notifier versions“.


Rememeber to ask you questions here.

Automatic subscription checkbox insertion seems not to work.

Your theme needs to call a specific WordPress action (“comment_form”) just after the comment form. The comment form usually is into the “comments.php” file of your theme. If this file is missing, WordPress uses the “comments.php” of the default theme. If this call is missing, you need to add it or to insert the checkbox by hand.

  1. Hi Stefano and thanks for the great plugin!

    Do you think it would be possible to insert link to the left comment and not simply the post URL into the notification email?

    That would be a very neat feature!


  2. Hi Admin, the plugin is sending Blank Emails to all subscribers. Some of my reader reported that they are getting Blank Email. I think this problem is associated with “Comment Notifier” plugin, kindly look at into this matter.

    Thank You

  3. Stefano,
    thanks for the plugin. I didn’t get the plug in yet. I do see the check box below a comment but when posting a comment I do not receive an email. Coming to your page I see you use the same theme as I do (what a coincidence). I don’t see ID); ?> in my comments.php. Did you add it or is it somewhere else? Where?



  4. I have a need to give an author the option to subscribe to the comments on a post they are typing on the composition page as the post is being typed.

    Then when clicking post, the post will be submitted and the author will be subscribed to any subsequent comments made to the post.

    The scope is this: I have a WordPress theme being used as a ticket/support system and I need the customers to be able to submit their tickets (posts) and also automatically be subscribed to the ticket comments (replies from myself, the tech) without having to go through the extra step of viewing the ticket after it’s posted and then choosing to subscribe to comments on it.

    Can I do this? If so, how?
    I’d also like to be able to hide the check box to subscribe and have it checked by default if possible, thereby subscribing myself and customers to the comments without them seeing the check box and being able to un-check it.

  5. Hi Stefano, happy new year!

    Just a suggestion of an idea that came to my mind today. I’m not sure if it would be possible, but would be very useful and cool if when I see the comments on Word Press, the comment would have some icon, character, informing that this comment is subscribed into Comment Notifier, otherwise it doesn’t show this character/icon.


  6. I like the way this plug-in works much better than the Subscribe to Comments derivatives (which don’t give you enough control over the email content). However, I would really like to see you add a double opt-in feature, as I have a lot of spammers signing up to it with false emails on my blog (don’t ask me why they would do this, but they do!).
