Your Email Campaign ROI % represents the return on investment (ROI) from your email marketing campaign. It tells you how much profit you earned for every dollar spent. A positive ROI means your campaign generated more revenue than it cost — a sign of effective outreach and strong audience engagement. A negative ROI indicates that your campaign cost more than it earned, which may point to issues with targeting, messaging, or conversion. Example: An ROI of 150% means you made $1.50 in profit for every $1.00 spent on your campaign.
