Notification emails go to spam when using Subscribe To Comments Reloaded

Subscribe To Comments Reloaded is a useful plugin which enables commenters to sign up for e-mail notification of subsequent entries. This plugin includes a full-featured subscription manager that your commenters can use to unsubscribe to certain posts or suspend all notifications.

However, notification emails will go to spam in some cases. For example, Gmail mail server might recognize your notification emails as spams.

Specifying an email address with your domain name as the sender email address will help to avoid this issue. For example, if your domain name is '', you might be able to '' as a sender email address. It's fine if this email address does not exist.

How to prevent your emails from being spammed

Under the Notifications tab of WordPress Dashboard > StCR, you can enter the Sender email address field. And you can add your active email address to the Reply To field.

(Similarly, when you cannot receive notifications emails sent from Contact Form 7, you can set an email address with your domain name as the sender email address to avoid email delivery failure.)

In some themes, Subscribe To Comments Reloaded will not work properly. I enabled this plugin with Avada, the Subscribe select drop-down list did not appear. In the theme Publisher used on this blog, the Manage Subscription page did not work as expected. For this reason, I hid the option to subscribe all comments from the drop-down list.

Subscribe comments in WordPress

To hide the "All" option from the select drop-down list, you can add 'display: none;' to the wp_subscribe_reloaded.php file under the folder /wp-content/plugins/subscribe-to-comments-reloaded:

<option value='yes' " . ( ( get_option( 'subscribe_reloaded_default_subscription_type' ) === '1' ) ? "selected='selected'" : '' ) . "style='display:none;'>" . __( "All", 'subscribe-reloaded' ) . "</option>

You know, it's not a good idea to modify the plugin source files since the changes will disappear when the plugin is updated. It's possible to hide the "All" option with the following CSS code:

select#subscribe-reloaded > option:first-child + option {
display: none;

I used the Disqus comments system for years on my Korean blog. However, due to some issues, I recently reverted it back to WordPress default comments system. Google may or may not index Disqus comments. The comments on my blog were not indexed. So I decided to use WP default Comments system.
