How to subscribe to an entry and get notified by email in case of new comments?
I really like the idea of using a simple plugin like Like to keep track of what entries users are interested in.

But instead of writing the code to integrate with Postmaster, I’d probably just use Craft’s API directly to send the mail after new entries are saved in your comments section.

The Like plugin and Craft API you need to look into:


entries.onSaveEntry event
getLikesByElementId()
sendEmailByKey()
