1 second is too long for a message to be marked as read after display

1 second is too long for a message to be marked as read after display. I’d like to define this in MS instead of seconds. I think 400-600ms would be the sweet spot for me if eM Client let me set it that granularly.

Hi Abdul, this is not possible, but if 1 second is too long, you can set the interval to 0, and your messages will be marked as read right after the click.
We’re not considering making this option in milliseconds.

Thank you for understanding,
Paul.
