Email Open Rate Calculator
Measure the effectiveness of your email subject lines by calculating the percentage of opened emails.
Email Open Rate is the first hurdle in any email marketing campaign. It measures the percentage of delivered emails that were opened by recipients, primarily reflecting the strength of your subject line and sender reputation.
Open rates are critical for ROI because if an email isn't opened, it has zero chance of converting. A high open rate ensures that your promotional content reaches the audience, maximizing the value of your existing subscriber list and the effort spent on content creation.
