I noticed on my forum that when a category is muted, topics from that category still show up in summary emails.
This is unexpected behavior because my assumption is that muted categories, which is defined as never being notified about new topics in this category, wouldn’t show up in the summary emails either.
Here’s an example of a user who has muted “Internal Comms”
When I previewed their summary email, Internal Comms showed up.
I propose that summary emails do not include topics from muted categories unless that specific topic within a muted category has a different status.
