This is the Blogger help info:
Thank you for your patience. I'm happy to
inform you all that the email notifications for comments capability is
now functioning with some additional improvements:
What's changed:
When an email address is added in the Comment moderation (Settings > Posts, comments and sharing > Comment moderation), Comment Notification Emails (Settings > Email > Comment Notification Email), or Email posts to (Settings > Email > Email posts to)
fields, notifications are not necessarily enabled as they were before.
Instead, if an email address is added to these fields, an email is sent
inviting the email owner to either accept or decline the subscription.
If the owner accepts, they will receive email notifications on new
posts/comments. If the owner declines, the email address will be
immediately removed from the field in their Settings.
Please note that when you enter an email alias that includes multiple members (for example: myc...@googlegroups.com), all members of the group will receive the invitation to either accept or decline the subscription.
When
email notifications are sent, an unsubscribe link will also be
available at the bottom of the email, should the recipient(s) wish to
opt-out. Therefore, if any member of a group alias clicks the
'Unsubscribe' link, the entire group alias will be unsubscribed.
