Works with all CF7 form types and shortcodes No plugin install, no PHP edits Free tier · no card

Works with every CF7 form on your site.

Any Contact Form 7 form, anywhere on your WordPress site. Shortcode-embedded, in widgets, on landing pages, in popups. No per-form configuration. Works with Flamingo, the official storage add-on, but doesn’t require it.

The CF7 attribution problem

An email arrives. That’s the whole product.

Contact Form 7 is deliberately minimal. It sends you a notification email with the field values. There’s no source data anywhere. Not in the email, not in Flamingo, not in the database.

CF7 is great at what it does. Attribution just isn’t what it does.

How it actually works

One snippet on your WordPress site. Source on every CF7 submission.

  1. 01
    Lead Source captures the visitor’s real source, campaign, and page journey when they land on any page of your WordPress site. UTMs, referrer, ad click ID, full session journey.
  2. 02
    When the visitor submits a CF7 form, Lead Source intercepts the submission client-side and forwards the form data and source to your Lead Source inbox. Alongside CF7’s normal email notification.
  3. 03
    CF7 keeps doing what it does. Sending the notification email, writing to Flamingo if you have it installed, running your existing CF7 actions. Lead Source adds the source data in parallel without touching CF7’s flow.
  4. 04
    No PHP, no plugin install, no functions.php edits. Just the snippet in your site header.
The snippet

One line, before the closing </head>.

<script async src="https://cdn.leadsource.co/track.js" data-site-id="YOUR_SITE_ID"></script>

Drop this in your WordPress theme header (or use a plugin like Insert Headers and Footers). Lead Source auto-detects all CF7 forms on the page and binds the source data on submit. No per-form configuration.

Three-step install

Done in five minutes.

01

Add the snippet to your WordPress site

Easiest path: install Insert Headers and Footers (or any equivalent), paste the script into the “Scripts in Header” box, save. Comfortable in PHP? Drop it into your theme’s header.php before </head>.

02

No CF7 configuration needed

Lead Source detects every CF7 form on every page automatically. No shortcode changes, no plugin install, no functions.php edits. Existing CF7 setups work as-is.

03

Submit a test form

Open one of your CF7 forms with a UTM in the URL (e.g. ?utm_source=google&utm_campaign=test) and submit. You’ll see the new lead in your Lead Source dashboard with the source, campaign, and page journey. Alongside the CF7 email that lands in your inbox.

Common questions

Questions, answered.

Do I need to install a WordPress plugin for this?

No. The Lead Source snippet is plain JavaScript. It goes in your site's , no plugin required. The easiest way to add it on WordPress is via a header-and-footer plugin, but that's not Lead Source. It's just the standard way WordPress sites inject scripts.

Does this work with Flamingo?

Yes. Lead Source runs in parallel. CF7 still writes to Flamingo for storage, and the source data lives in your Lead Source dashboard. Flamingo gets the form fields; Lead Source gets the form fields plus the source.

Will this break my existing CF7 actions or integrations?

No. Lead Source captures form submissions client-side without intercepting or altering the CF7 submit flow. Email notifications, Flamingo logging, Mailchimp connections, and any other CF7 integrations keep working as before.

What about CF7 forms inside popups or modals?

Works. Lead Source binds to CF7 forms whenever they appear in the DOM, including dynamically-loaded popup forms from plugins like Popup Maker or Elementor popups.

My host blocks third-party scripts. Can I self-host?

The Lead Source snippet is served from our CDN by default. For locked-down hosts or stricter CSP setups, contact us. We can issue a self-hosted version of the tracker that lives on your domain.
