According to MailerMailer, 74.5% of emails are opened within the first 24 hours and 84.3% occur within the first 48 hours. This theory provides an insight on how the emails are being opened by your recipients. This data is based on aggregate statistics from over 300 million email messages sent by a sampling of over 3,000 permission based email senders. So the implication of this theory is that when you are sending an email you should start seeing the results within duration of 2 days. This is a very important data as far the success of the email marketing is concerned. So, when you design a newsletter with a given idea and you want to test the same with another idea then you don’t have to wait for a week to know which email campaign was successful. You can check out its success rate just within 2 days. So your email campaign’s success just lies within these first two days when you sent your newsletter.
