While creating new proofs, there's a moment when you configure proof stages. This part consists of a few actions: inviting reviewers, adjusting stage settings, e.g., deadline, selecting the final status calculation, etc.
There's also an option to select notification preferences for invited reviewers. Near each reviewer inside the proof workflow, there is a notification setting that can be applied independently for each contact.
Here's a short summary for all available notification options:
All comments and decisions - sends out all the activity notifications immediately.
Replies to my comments - send out only notifications related to reviewer comment replies.
Decisions - sends out only decision notifications.
Final Decision - sends out only a final decision notification for the whole proof.
Hourly digest - if you enable Hourly digest for a reviewer, they will get a notification on a full hour as long as there was any activity on that proof. This notification combines all proof of activity in one email.
Daily digest - if you enable Daily digest for a reviewer, they will get a notification with all activities during the 24-hour period. This notification combines activity for that day into one email for each proof. Daily digest notifications are scheduled to be sent out at 9:00 am, Coordinated Universal Time (UTC).
None - it blocks all notifications (apart from New proof to review email & @mention notifications).
Updating notification preferences
If you need to update some notification preferences for an already existing proof, you'll need to enter proof mode, click Edit near the selected reviewer, and then choose a new setting accordingly.
