There are several methods to measure satisfaction scores in email marketing:
Surveys: Send follow-up surveys to your subscribers asking them to rate their experience with your emails on a scale (e.g., 1-10). Net Promoter Score (NPS): Ask subscribers how likely they are to recommend your emails to others on a scale of 0-10. Click-to-Rate: Measure the percentage of subscribers who click on links within your email. Open Rate: Track the percentage of subscribers who open your emails. Conversion Rate: Measure how many subscribers take a desired action after clicking through your email.
