When running affiliate email campaigns, tracking deliverability metrics can help you understand how many people are actually receiving your emails. The most common metric to watch is the bounce rate. A high bounce rate means many emails aren’t getting delivered. Also keep an eye on your open rate, because if people aren’t opening your emails, it could mean they are landing in the spam folder. Another important one is the spam complaint rate. If too many people report your emails as spam, it can damage your sender reputation. Your click rate is also useful, as it shows how many people are interacting with your content. Watching all these together gives you a clear picture of your deliverability health. If something drops suddenly, it could be a sign to review your email practices. What would you look out for if you were checking your own email campaign’s performance?
