If email templates have not been modified we can Revert to the Default templates, which should clear the template cache and thus the missing .CSS files would be cached again:
From Email templates
Reverting templates to default
If something isn't right with your modified templates, you can bring the default ones by clicking Revert to default. Here's what happens when you do it:
Jira copies the default templates from its resources to the Jira shared home directory.
The default templates overwrite any existing templates in
<Jira-shared-home>/data/templates.After a successful revert, we clear the template cache, so the default templates are applied right away.
This should result in all of the Notification emails being formatted correctly
