Our New Plugin: Email Commenters
We brought you a brand new free WordPress plugin to send emails to your post commenters, it's a very simple one.
There is a similar plugin Email Commenters with the same motto, but it hardly solves the issue simply. It just puts an email icon on at the admin bar and clicking that link goes to your email client. And it didn't work for me.
So here's the plugin, just select all posts or select a single post and click next. All the email addresses will be fetched and will be added to the Bcc list. Compose your mail and give a subject, hit send. Easy as pie.
You can select a single post or all posts.
