I doubt we need that to be honest as search on new modmail is already rolled out.
Thoughts?

I'd say we can skip the search part, yep.

We can skip the search, but we should make sure whatever we're using to send modmail alerts would still work with new modmail too.

[AlMcKinlay]

This is done, right?

Here's the latest on new modmail, but tldr yes mostly

Also, I think we should also add [Notification] to the beginning of FHQ notifications so that they land in the correct section:
