This simple plugin automatically sends a notification email to commenters when someone replies to their comment. This feature can be enabled automatically by the site admin, or through an opt-in/opt-out checkbox below comment section on frontend. It’s best to use it with an email-sending plugin like WP Mail SMTP, and with SMTP or transactional email service like SendGrid or Mailgun. Sending from your server via PHPmailer can cause deliverability issues (email notfications caught in spam). I loved the original plugin Comment Reply Notification (by @denishua) for its simplicity but it was abandoned and stopped working years ago. So I forked and revived it to work with the latest PHP and WordPress. I also improved some wording, removed unnecessary author links in the email notifications, and also keep it more updated. Credits to Denis who first hacked it 5 years ago, and later Walter for fixing string escapes. Features: Feature modes – disabled, author/admin replies only, automatically, checkbox opt-in. Edit email notification – subject and message. [year] shortcode for dynamic year in email templates. Developer-friendly hook for adding custom shortcodes. Fixes issue with email notifications for moderated comments. Can delete plugin options – after deactivation.

This plugin allows visitors to subscribe to get answers to their comments via e-mail. Warning 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. Sending e-mails does not work? The plugin uses the standard WordPress e-mail function. If you have problems getting e-mails sent, you might try using plugins like https://wordpress.org/plugins/wp-mail-smtp/ to improve sending e-mails from your site. Customizing the layout of the checkboxes The label next to the checkboxes don’t contain a whitespace. Depending on your theme you might want to add a custom style like this to get a space between the checkbox and the label: input#cren_subscribe_to_comment, input#cren_gdpr { margin-right: 0.5em; } The plugin does not add this style be default as it depends on your theme if this is neccessary. Customizing the email template To customize the email template, copy the “templates” folder to your theme folder (a child theme should be used to avoid losing the custom templates when the theme is updated). 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: https://github.com/arnowelzel/worpdress-comment-reply-email-notification/tree/master/templates 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. Modifiying HTML output Using the filters cren_gdpr_checkbox_html and cren_comment_subscribe_html you can modify the HTML output of the checkboxes if needed. Example: add_filter('cren_gdpr_checkbox_html', function(string $html_output, string $label_text, string $privacy_policy_url): string { $html_output = ' ' . $label_text . ' * ( Privacy Policy ) '; return $html_output; }, 10, 3); add_filter('cren_comment_subscribe_html', function(string $html_output, string $label_text, bool $checked_default): string { $checked = $checked_default ? 'checked' : ''; $html_output = ' ' . $label_text . ' '; return $html_output; }, 10, 3);
