open rate
noun1
Business, Marketing Internet A measure used by marketers as an indication of how many people "view" or "open" the electronic mail they send out.
- You calculate your open rate by using your non-bounce rate instead of the total e-mails sent because your open rate indicates the strength of your e-mail's identity and content apart from the strength of your deliverability.2011, John Arnold, E-Mail Marketing For Dummies, John Wiley & Sons, →ISBN:
