When emails appear greyed out and aren't populating properly, this could be due to a few reasons:
1. If you're using "write to table" functionality, the value might not be formatted correctly as a list. Try adding the list through the "Other data from this table" section.
2. You might be experiencing a front-end performance issue. Try clearing your cache and refreshing your screen.
3. Changes to source filters won't automatically update existing data. Clay doesn't reprocess previously generated data automatically, even if the source preview shows new filters.
To resolve this, you'll need to either delete and re-run the step or duplicate the table with the updated source.
