  1. InternetbusinessA 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.
