Within the days of the week, the time of day also plays a crucial role. Studies suggest the following optimal times:
10 AM: This is often considered the peak time for email opens, as people have settled into their workday and are checking their inboxes. 1 PM: Around lunchtime, people often check their emails, making this another good time to send. 6 PM: After work hours, people might check their emails one last time before ending their day.
