Gist Notifications is an Always Be Closing (ABC) feature that periodically sends you an email notification when someone has posted a comment on one of your gists. GitHub does not notify you when someone posts a gist comment. The notifications are sent in a batch digest once every 24 hours. If there are new comments then you’ll receive an email.
The emails will have the following format:
The following GitHub gists authored by [username] have new comments:
[user1] commented 3 hours ago
This is a gist comment.
[user2] commented 1 hour ago
This is another gist comment.
Gist Notifications is unable to monitor private gists. This limitation is caused by a bug in the GitHub API. To unsubscribe from these emails go to the configuration dashboard and disable the “Gist Notifications” feature.
