Hi Andy,
Thanks for testing the plugin and for the detailed explanation.
The plugin stores UTM parameters in cookies when a visitor first lands on the site with UTM values in the URL. Once stored, the values should persist for up to 30 days and be attached to Contact Form 7 submissions even if the visitor browses multiple pages before submitting the form.
On some managed hosting environments such as WP Engine, aggressive page caching or JavaScript optimization can occasionally prevent the tracking script from running on the initial page load.
I’ve recently released version 1.5 which improves cookie handling and compatibility with caching environments. Could you please try updating the plugin and testing again?
If the issue persists, it would be very helpful to know:
• which page the visitor first lands on with UTM parameters
• whether any JavaScript optimization or script delay features are enabled
With that information I should be able to reproduce the issue and provide a fix.
Thanks again for the report!
