It depends on their settings. If they commented on a blog that is not their own and you replied to their comment, the only way they’d receive notification is if they check marked the “Notify me of follow-up comments via email”.
If it is their own blog they commented on and you replied to it, they will receive notification of your comment if they have chosen to receive them via email.
There are other means of looking at people’s replies to comments, such as through the Dashboard, and the Notification button at the top of the page.
The topic ‘Comment reply’ is closed to new replies.
