There’s a good chance your email to a friend will be opened. But marketing emails are very different. If you sent a marketing email on say Saturday afternoon, then chances are this message will not be read when the typical recipient opens their email app to a deluge of messages on Monday morning. This infographic from the team over at Get Response shows some better open time ‘windows’ and gives some insight as to the best time to send.
One stat I like: Emails achieve their best results (open rates) within the first hour of delivery.
