Unify Your Analytics: The CRM-Driven Campaign Tracking Playbook

Are your marketing analytics a mess? When different team members use inconsistent tags like 'facebook', 'Facebook', and 'fb' for the same campaign, your data becomes fragmented. This makes it impossible to get a clear view of channel performance in Google Analytics, leaving you to guess about your marketing ROI and misallocate your budget.

This playbook provides a step-by-step guide to building a 'CRM-Driven Marketing Hub.' By integrating a free HubSpot CRM with the affordable MailerLite email platform, you create a powerful, centralized system for tracking.

This closed-loop system connects your marketing sends directly to lead capture and conversions in your CRM, giving you a crystal-clear view of what's actually working.

Integration Logic

  • CampaignFlow Connector

    This integration creates a three-way data flow. First, new or updated contacts in HubSpot that meet specific criteria (e.g., a custom property is set) are automatically added as subscribers to a designated MailerLite group for email nurturing. Second, all links in MailerLite campaigns are automatically tagged with custom UTM parameters, allowing Google Analytics 4 to precisely track user traffic and behavior from these campaigns. Finally, key conversion events tracked in Google Analytics 4 (like purchases or form submissions originating from a MailerLite campaign) are sent back to HubSpot. This updates the original contact record, for example, by changing their lifecycle stage to 'Customer' or creating a new deal, thus closing the loop and providing clear ROI.
