Hi, Carmen!
Great question! If a reviewer has an Articulate ID and is logged in to their account, they can mute notifications; however, if they don't have an Articulate ID, they won't see this option. In this case, they will receive notifications for comments they've created, they're mentioned in, and have already replied to. For now, you may consider resolving the comments you've worked on. This shouldn't send an email alert to your stakeholders.
If you export the comments as .csv, you can add a column to the sheet in Excel for your indication that the comment was resolved, and email the final sheet to stakeholders.
