How to Track UTMs in Sendinblue form

UTM attribution overview

This guide explains How to Track UTMs in Sendinblue form with HandL UTM Grabber. It helps you pass lead attribution into your CRM, email platform, or marketing automation workflow and keep the marketing context needed for accurate reporting across forms, bookings, signups, and sales.

Add Contact Attributes

Go to Settings > Contacts atributes

Add all the UTMs and other parameters from UTM Grabber as shown below. Native WP Shortcodes

Add the fields in your form

You can add the new fields in your form using "Add a new field" feature

Or simply copy paste the following code, anywhere in the form

<p class="sib-UTM_CAMPAIGN-area"> 
<input type="hidden" class="utm_campaign" name="UTM_CAMPAIGN"> 
</p>
<p class="sib-UTM_SOURCE-area"> 
<input type="hidden" class="utm_source" name="UTM_SOURCE"> 
</p>
<p class="sib-UTM_MEDIUM-area"> 
<input type="hidden" class="utm_medium" name="UTM_MEDIUM"> 
</p>
<p class="sib-ORGANIC_SOURCE-area"> 
<input type="hidden" class="organic_source" name="ORGANIC_SOURCE"> 
</p>
<p class="sib-TRAFFIC_SOURCE-area"> 
<input type="hidden" class="traffic_source" name="TRAFFIC_SOURCE"> 
</p>

NOTE: interestingly the wrapper div is required :)

We have added only some UTMs, organic_source and traffic_source as an example. You can add as much fields as you wish.

Make sure the class variable matches with our naming convention here Native WP Shortcodes As long as you maintain that, our plugin will be able to aitofill the fields.

After that you can test and go to Sendinblue to confirm

Send Brevo Sendinblue UTMs via Zapier or Webhook

UTM attribution overview

This walkthrough covers sending full UTM Grabber data from Brevo Sendinblue to Zapier, Make, or your own webhook. Handy when you need gclid, fbclid, first-touch fields, or custom params alongside the lead or order.

For the primary setup, see the main Brevo Sendinblue guide.

When a webhook makes sense

Native fields in Brevo Sendinblue often stop at basic UTMs. A webhook lets you push everything UTM Grabber stores without trimming values or losing click IDs.

Thank-you page script

Paste this on your confirmation page. Swap in your Zapier or Make hook URL.

<script>
var qvars = {};
window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m, key, value) {
    qvars[key] = decodeURIComponent(value.replace(/\+/g, ' '));
});
qvars = Object.assign({}, (typeof handl_utm !== 'undefined' ? handl_utm : {}), qvars);
setTimeout(function() {
    var data = new URLSearchParams(qvars).toString();
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open('GET', 'https://hooks.zapier.com/hooks/catch/YOUR_ID/YOUR_KEY/?' + data, true);
    xmlHttp.send(null);
}, 1000);
</script>

Full pattern explained in Triggering Zapier on Thank you Page.

Quick Zapier / Make checklist

1. Create a Catch Hook trigger and copy the URL
2. Run a test conversion with UTMs in the landing URL
3. Confirm gclid, utm_source, and email (if present) show up in the payload
4. Map fields into your CRM or spreadsheet
