A couple of people asked recently how I send those automated emails that thank people for commenting. The answer is quite simple, it is a fantastic plugin called Comment Relish
Comment relish is a WordPress plugin developed to send an e-mail message to users who comment on your website who have never commented before.
A simple and elegant solution!
The way I use it is to thank commenters for their feedback and remind them of the subscription options. I don’t track how many people take it up but I think the thank you alone is well worth it 🙂
