The best time to distribute an email newsletter depends on your audience. Morning hours, like 9–11 a.m., often work well as people check emails early. Midweek days, especially Tuesday and Wednesday, usually see higher engagement. Avoid weekends when people may focus less on work-related emails. Time zones matter; schedule emails to match your audience's location. Analyze past email performance to find your best time. Testing different days and times helps optimize results. Consider your audience's habits, like checking emails during breaks or before work. A strategic schedule ensures higher open rates and better engagement.
