Limitation of this method is that you can only add at maximum of 100 members per month (Maximum tasks for Free Zapier Account). Please use viaSocket to increase maximum member to 3,000 In this tutorial I will guide you to collect users’ email from Caldera Forms and add them to Mail Chimp Subscriber List.

The Work Flow of this method is using Zapier to make a webhook to receive data from Caldera Forms, then submit those data to Mailchimp.

Making a Zapier Task

Firstly, you need to create a Zapier Task (a Zap). Every Zap need at least 1 Trigger and 1 Action.

1/ Set up Webhooks Trigger

Press Continue, we are done with Zapier part.

Trigger Webhook from Caldera Forms

In order to send data to Zapier, we need to trigger this webhook after user press submit on our contact form

Email will be replaced by actual email from users.

1/ Create a form to collect email from users

This is an easy part, just make a form with 2 fields:

  • Email field – Check this field’s ID, something like: fld_9099843
  • Submit Button

2/ Trigger Webhook after form submitted

In order to trigger webhook, we use an event from Caldera Forms cf.form.submit

This event will trigger any script after 1 Caldera Forms is submitted. This is complete code snippet.


// Use jQuery via $j(...)
  $j(document).on( 'cf.form.submit', function () {
    var $emailClient = $j("#fld_9099843_1").val(); 
    var $url = "";
    var $urlFull = $url + $emailClient;  

    var sendEmail = {
      "async": false,
      "crossDomain": true,
      "url": $urlFull,
      "method": "GET",
      "headers": {}
    $j.ajax(sendEmail).done(function (response) {

    //end of submit trigger
//end of ready
