Open Rate

A metric that measures the percentage of recipients who open a specific email out of the total number of emails delivered. It indicates how effective an email campaign is at capturing recipients' attention and encouraging them to engage with the content. The open rate is calculated by dividing the number of opened emails by the number of emails delivered (excluding bounces) and then multiplying by 100 to get a percentage.
