- Emails posts should be not explorable by the rest of the frontend similarly to the draft or scheduled posts. Email posts should also keep the content gating, so that specific parts of content can still be gated based on the post's visibility setup
- A separate frontend router was chosen to implement this part of the system instead of a moutable express app due to increased complexity to introduce the latter approach.
- All "sent" email-only posts will be accessible through the `/email/:slug/` route

- The frontend route `/email/:uuid` is aliased to the preview as a temporary solution. It fulfills the premise of the email-only post anyway - not being accessible publicly and only shared through email.
- The tests for the new route are missing as adding them was way more problematic than I envisoned. They are in the works and will be added as a follow up commit next.
