This simply adds a subscription checkbox to your WordPress comments form to let your visitors subscribe to comments. They will then be notified by email when others comment on the same post. Works automatically upon activation, no settings required.

This plugin focuses on a lightweight footprint and fastest pagespeed. No scripts are added. It simply just works upon activation. All settings are optional.

Easily Switch From Other Comments Subscription Plugins

Your subscribers will be imported for an easy switch from the following listed plugins. This is done automatically upon activation. Your comment subscribers will be migrated from these plugins:

  • “Subscribe To Comments” plugin
  • “Subscribe To Comments Reloaded” plugin
  • “Comment Notifier” plugin

Optional Settings include:

  • You can unsubscribe people, if you wish.
  • You can customize the notification emails.
  • Set a custom “Unsubscribe Page” URL or unsubscribe message.
  • Send a “Thank You” message for first time commentators.
  • Send a copy of EACH notification to emails of your choice.

Special Condition For “Comment Notifier” Plugin Users:

“Lightweight Subscribe to Comments” fixes a major problem with the “Comment Notifier” plugin:

In particular, “Lightweight Subscribe to Comments” fixes this problem.

Lightweight Subscribe to Comments will not subscribe spammers while their comment is pending moderation. Only approved comments will be subscribed. Comments authors in moderation will only be subscribed if, and when, you approve their comment.

The problem is that “Comment Notifier” plugin subscribes the email address as soon as the submitted comment goes into moderation. This means that spammers get added to the list of subscribers, immediately. Later, when you delete the spam comments, the spammer’s email remains in the list of subscribers.

You could have hundreds, even thousands, of spammer email addresses in that list. Then, when you approve a legit comment, your server sends out emails to all of the post subscribers (including spammers), which can cause server overload, among other problems.

This plugin fixes that by ignoring comments in moderation until they are approved by you. This means less load on your server.

Bonus Clean Up For “Comment Notifier” Plugin Users:

This plugin removes spammers from your “Comment Notifier” list.

Upon activation, this plugin will clean up your “comment_notifier” list (database table) by removing all spammer emails (emails of people that do NOT have an approved comment). (This only applies to you if you were using the “Comment Notifier” plugin.) It will also empty your Comments “Trash” and “Spam”. This clean up is only done once, upon plugin activation.


This plugin is translation-ready and includes a .pot file to make it easy to translate.
