Email Open Rate Calculator
The email open rate is a key metric for measuring the success of your email marketing campaigns. It represents the percentage of recipients who opened your email out of the total number of emails successfully delivered. A higher open rate generally indicates that your subject lines are compelling, your audience is engaged, and your sender reputation is strong.
Calculating your open rate is straightforward. You need to know the total number of emails sent and the total number of unique opens your email received.
Calculate Open Rate
function calculateOpenRate() {
var emailsSent = parseFloat(document.getElementById("emailsSent").value);
var uniqueOpens = parseFloat(document.getElementById("uniqueOpens").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(emailsSent) || isNaN(uniqueOpens)) {
resultDiv.innerHTML = "Please enter valid numbers for both fields.";
return;
}
if (emailsSent <= 0) {
resultDiv.innerHTML = "Total emails sent must be greater than zero.";
return;
}
if (uniqueOpens emailsSent) {
resultDiv.innerHTML = "Unique opens cannot be greater than total emails sent.";
return;
}
var openRate = (uniqueOpens / emailsSent) * 100;
resultDiv.innerHTML =
"Your Email Open Rate is:
" + openRate.toFixed(2) + "% ";
