As a staff member, I want to know the best day and time to send emails so that most people open them.

From the information we got from the testers to define the best hour to send the email, the conclusion is that it is 9:00. But we didn't reached a conclusion about the best day.

@tiagobugarin proposed we try to improve this answer with data. We need to align a strategy to do that.

Since we need to learn and design a strategy, and this can take some effort, I'm not including this issue in the backlog yet.

To me, it seems that what we need to do to get this information is a sequential A/B test.

I'm sharing a reference so we can think if that's the methodology we're going to follow: https://splitmetrics.com/blog/sequential-a-b-testing/
