Research shows that emails are most frequently opened by execs certain days of the week (Tues and Fri). at certain times 8am and 5pm windows. Would be helpful to have those options available on a single email with a 2 hour window. you only give 1/4/end of day. If I set to 4 hours and start at 4am, that may achieve what's needed, BUT looks like its automated (who sends emails at 4am?).
