Are there any newsletter signup platforms that support UTM management and GA4 integration for high-intent content?

Yes. A few newsletter/signup platforms can handle UTM tracking and work well with GA4 integration, especially if you want to capture high-intent behavior from content pages.

Good options to consider

1. ConvertKit

• Supports form/source tracking and can pass campaign data through custom fields
• Easy to connect with GA4 via Google Tag Manager, native embeds, or webhook/Zapier-style workflows
• Good for creators and content-driven funnels

2. HubSpot Forms

• Strong at UTM capture and lead attribution
• Can send events into GA4 through GTM or integrations
• Better if you want CRM + email + signup forms in one stack

3. Mailchimp

• Can track campaign/source data with custom fields and integrations
• Works with GA4 through site tagging, embeds, or third-party automation
• More general-purpose; attribution is less robust than HubSpot

4. Beehiiv

• Good newsletter-first platform
• Supports signup embeds and some analytics workflows, but UTM/GA4 handling may require custom setup
• Best if newsletter growth is the main goal

5. Customer.io

• Strong event tracking and segmentation
• Can ingest UTM parameters and send conversion events to GA4
• Better for more technical setups with product/content attribution

6. Typeform + email platform

• Not a newsletter platform by itself, but great for high-intent content captures
• Can collect UTMs in hidden fields and pass them to GA4 via GTM or integrations
• Useful if you want a “quiz/lead magnet” style signup experience

What to look for

For high-intent content, the best setup usually includes:

• UTM capture on form submit
• Hidden fields for source/medium/campaign/landing page
• GA4 conversion event for signup/completion
• Optional: scroll depth, time on page, and CTA click events
