This would be very beneficial. Our clients are always asking what time
their emails are opened most, to optimize delivery time. We'd like a way
to group any delivery based on the hour of day, rather than a full
report of every hour of every day in the time-span for the report is
generated. If the data flowed into Analytics with the proper time, with
more granular or grouped/calculated metrics, we could easily provide
these insights to our clients.
