What is Email Open Rate ROI Calculator?

Email marketing consistently delivers one of the highest ROIs of any digital channel — but only if you are tracking performance correctly. This calculator measures your open rate and revenue per email sent, giving you the data you need to optimize every future campaign.

How to Use This Tool

1. Enter the total number of emails sent in your campaign. 2. Input the total number of emails opened. 3. Enter the total revenue generated from this campaign. 4. Calculate your open rate and revenue per email.

💡 Pro Tip: Subject line testing (A/B split) is the single highest-leverage email optimization. A 5% improvement in open rate on a list of 10,000 means 500 more people see your message every send. Use this calculator to quantify what that improvement is worth in revenue!
