Motivate Your Commenters To Come Back

People come to your blog, some of them comment on your posts. Probably then you will answer on the comment on your blog. But are you sure the person who commented will come back again and see how you value his/her opinion? You can never be sure about that. There is one great plug-in that can show people who never commented before that you really appreciate their opinions and by that opportunity you can invite them to check your blog again.
Comment Relish is a plug-in that allows you to send an e-mail to the person who commented on your post for the first time. If you will formulate the answer in a friendly manner, they will appreciate your care and will be coming back.
