Newsletter Analytics: Beyond Open Rates

Your email platform tells you:

• 45% open rate
• 12% click rate
• 500 clicks this week

What it doesn't tell you:

• How many clicks became customers?
• Which issues drove the most revenue?
• What's each subscriber actually worth?

TrackFox connects your newsletter to revenue.
