Is your feature request related to a problem? Please describe.
When I receive email notifications, I see the following template:
September 9, 2026, 3:39
User XYZ created file1, file2 and file 3

When there are a lot of files, this gets confusing and is in principle just a long one-liner.

Describe the solution you'd like
I'd like to have the files as list items or with a
between them.
E.g.:

September 9, 2026, 3:39
User XYZ created:
file1
file2
file3

Best those files were sorted alphabetically before they are displayed so all paths are stacked.

Describe alternatives you've considered
None.

Additional context
None.

The issue names no files or tests. Start by locating the immediate email notification template and its rendering entry point; compare output for a notification containing several files. Done means the files are displayed on separate lines or as list items and are sorted alphabetically.
