In platform email updates

With the introduction of featurebase, new workflows, and benefits for producers the current email communication the platform sends out feels outdated and incomplete.

We should update the emails to be more inline with our brand voice and more relevant to our actual workflows.

The existing email templates are linked here:

We should:

1. Propose updates and re-writes to all emails (we shouldn’t skip any)

2. Identify if any can be removed - and if so whether they need to be replaced

3. Identify if we want to add new emails

4. @Stephanie van Dee and @Olivia de Seze should have the final say

5. @Rhys Davies will give the final thing to the developers to implement

6. Set up a monthly 30 minute check-in to see if anything needs iterating over.
