Send emails directly from client-side JavaScript without exposing credentials. Use Zapier to handle email sending securely from the browser.

This solution leverages Zapier’s Catch Hook to receive data from your JavaScript and send emails without server-side code or exposed credentials.

Preparation

Create your Zap with “Catch Hook - Send Outbound email”, i.e. https://zapier.com/app/editor/template/62

Zapier Catch Hook setup for sending emails

Zapier will give you an URL to send your data, such as https://hooks.zapier.com/hooks/catch/123456/abcdef/

Walkthrough

You can then call from your JavaScript:

var data = {
  email: "[email protected]",
  data1: "123",
  data2: "456",
};
try {
  var xhr = new XMLHttpRequest();
  xhr.open("POST", "https://hooks.zapier.com/hooks/catch/123456/abcdef/");
  xhr.send(JSON.stringify(data));
  console.log("Pushed to Zapier successfully!");
  alert("Success");
} catch (e) {
  console.error(e);
  alert("Error");
}

Validation & troubleshooting

Monitor all your calls from a single place:
