Email Marketing: Most Emails Opened Within a Day of Receipt
By Anna Johnson on July 26th, 2010Whatever your response you get from an email campaign, you’ll likely get the biggest response within the first day of the mail-out. Experian Cheetahmail’s study of 40,000 emails sent in March 2010 shows that the greatest proportion of email opens and transactions occur within a day of recipients receiving the email.
As the results below indicate, 76 to 84 percent of all emails opened are opened within a day of being received. Once a week has passed, almost all emails that will be opened, have been opened.
Emails notifying recipients of an abandoned shopping cart generate the greatest percentage – 84 percent – of all opens within a day of being sent. Meanwhile, when it comes to email-prompted transactions, emails containing time-limited offers elicit the biggest response on the first day after sending (59 percent of all email-prompted transactions), followed by free shipment emails (53 percent) and offers (49 percent).
Here are the percentages of emails opened within 1, 3 or 7 days according to their subject line:

By my personal experience, I’ve found that emails yielded the best results – not only opens but clicks and sales – are the ones that are opened in the first 24h. In addition, sending during business hours and avoiding the Monday inbox clutter is a sure shot at getting better opens.
