The list of who opened an email and at what time is good, but it would be even better if the open times were available as a bar graph or some type of graph. Each bar could represent an hour (8am-9am, 9am-10pm, etc.), this way we could see which hour had the highest open rate. Keep the list of people and their emails--that's good and needed for times when we need to group together the people that actually open our emails. Please, PLEASE consider adding a bar graph feature. Thanks!
