Comment Reply Email Notification


This plugin notifies a comment author via email when someone replies to his comment.


  • PHP 7.0+
  • WordPress 4.4+


This plugin uses the „wp_insert_comment“ hook, therefore, everytime a comment is created, a notification is likely to be sent. If you are importing comments into your blog, it’s a good idea to disable this plugin.

Customizing the email template

To customize the email template, copy the „templates“ folder to your theme folder. The plugin will look for templates on the „/wp-content/themes/[THEME]/templates/cren/“ folder; if a custom template is not found, then it will fallback to the default template.

Templates folder on GitHub:

Changing the subscription checkbox label

The checkbox label can be changed with the cren_comment_checkbox_label filter. This way you can update the text to your taste and keep the plugin updated.

Changing the GDPR checkbox label

The GDPR checkbox label can be changed with the cren_gdpr_checkbox_label filter. This way you can update the text to your taste and keep the plugin updated.

How to install the plugin:

  1. Upload the ZIP file to your WordPress installation directory
  2. Extract the ZIP file contents to the /wp-content/plugins directory.
  3. Plugin aktivieren.
  4. For better results, setup a plugin to send emails using SMTP.


Works great, only lacks Double-Optin-feature for GDPR

The plugin works great so far, but it lacks the feature of a double-optin-mail to verify the email-adress of the commenter. If that and the customization of the sender email adress would be added, I will give 5 stars 🙂 Have a nice day everyone!

Working on multisite!

Simple and the best plugin! And also it is working well on WPMU. I really appreciate it! Thank you so much for this awesome plugin... Regards!

It works fine if you take some time tweaking it.

Hi, Thanks for the plugin. First I realized uninstall and reinstalling keep all of the setting. Please be kind enough to clean up the settings when uninstalled. Update: He replied that he will work on it Also, template, with some tweaking, you can make customized email.

Good and simple!

U have a little bug in your Plugin. Check the subscription checkbox by default <= This setting in the Adminsection will be ignored. It is always enabled! change your function from function cren_get_default_checked() { return cren_get_option('cren_subscription_check_by_default', true); } to function cren_get_default_checked() { return cren_get_option('cren_subscription_check_by_default', false); } Currently, the checkbox is always checked.
