Final answer:
A high pass-on rate demonstrates that subscribers value your email content highly and are inclined to share it with others. It is a positive engagement metric that suggests your content is making a significant impact and resonates with your audience.
Step-by-step explanation:
A high pass-on rate indicates that your list values the content enough to constantly share with others. This metric reflects the extent to which your subscribers find the content of your emails worth sharing within their network. A high pass-on rate is a positive indicator of the engagement and values your audience places on the information you provide. It suggests that your content resonates with recipients to the degree that they actively decide to pass it on, thereby expanding its reach and potentially increasing your audience.
An unsubscribe rate or a number of bounces are negative metrics that reflect disinterest or problems with deliverability, respectively. The number of e-mails opened or open through-rate measures different aspects of engagement, such as the initial interest in the e-mail and the subsequent action taken after opening it. However, the pass-on rate specifically concerns the sharing behavior of your audience, which directly reflects the perceived value of your content.
