When you update the status of a Post, you'll see this option to "Notify all voters":
If you save with notifications enabled, voters will get a custom-branded email like this. The email will include any images/screenshots you add to the update as well:
Things to know:
Only users with access to the Board will get notified. If a voter does not have access to a Private Board, they will not receive status change emails for posts on that Board.
There is an unsubscribe link at the bottom if they wish to stop receiving updates like these.
If a user replies directly to the email, the reply is not recorded on the Post.—They need to click the "View Post" button in the email to add their comments or navigate to the Post page.
Canny Admins will not receive a status update email, but status changes are included in your Admin Reports as a digest!
This is an easy way to notify everyone of progress on a feature they care about. Closing the feedback loop has never been more simple!
