Add Date to Email Campaign Metric Details
Automated email campaigns are designed to send over a long period of time. Available metrics provide insight on performance, but lack the context to measure how that performance may change over time.
Adding date context to the tables when you expand the Email metrics would allow CMs to do this when needed.

- MVP: Send date in each of these metrics
- Ideal: Date of the event for each metric (Delivery, Open, Click, Spam, Unsubscribe)
