Measuring email deliverability involves various metrics, such as:
Bounce Rate: The percentage of emails that couldn't be delivered. A high bounce rate can indicate list quality issues. Open Rate: The percentage of recipients who open your email. Although not a direct measure of deliverability, low open rates can signal deliverability issues. Click-Through Rate (CTR): The percentage of recipients who click on links in your email. Low CTR can indicate poor content relevance or deliverability issues. Spam Complaints: The number of recipients who mark your email as spam. High spam complaints can severely impact your deliverability.
