Hi @Ajaz Khan ,
is it expected behavior or is there a way to get all the emails to show up in the review?
This is actually the expected behavior and as far as I know, currently there is no option available to get all results show up in the preview.
As indicated in the name "Review sample", it's just a sample of the search result, rather than the complete search result. So, only some randomly selected items would display in the preview.
