When optimizing for conversation in email marketing, what key metrics should you focus on?

When optimizing for conversion in email marketing, focusing on the open and click rates is essential because these metrics directly reflect audience engagement with your email content. The open rate indicates how effective your subject lines are at capturing attention, while the click rate shows how compelling your email content is in encouraging readers to take action. Higher values in these metrics usually suggest that your emails resonate well with your subscribers, leading to increased conversions.

The number of subscribers, while important for overall reach, does not necessarily indicate how well your emails are performing in driving a specific action after the emails are opened. Similarly, while monitoring the unsubscribe rate can provide insights into audience retention and satisfaction, it doesn't directly measure engagement with the content. Lastly, the deliverability rate is crucial for ensuring emails reach inboxes, but it does not provide insight into how recipients are interacting with those emails. Therefore, the most relevant metrics for optimizing conversions focus on engagement, which is best reflected through open and click rates.
