Is there any setting or plug-in that sends email notifications when someone comments on a card?

[Sarah Davidson]

My co-workers and I are needing to receive email notifications when someone comments on a card and not just an overall "here's what you missed" from Trello, is there any setting or plug-in that will do this? Thank you.

Hey Sarah,

We do offer email notifications and a new notification will be triggered for you if you are a member of the card that the comment is posted on (or subscribed to the card).

Please also ensure that you have your email notifications set to instant.
