Practical end-to-end examples using the Google Analytics addon. The main walkthrough proves how much revenue an email campaign generated: turn on UTM tagging with utm_campaign set to the {{campaign_name}} token, send the campaign, then in GA4 open Reports → Acquisition → Traffic acquisition and switch the dimension to Session campaign, where your campaign name appears beside its sessions, key events and revenue. A second example uses utm_content to settle which call-to-action works — tag a header button as header_button and a footer link as footer_link, then group by Session manual ad content to see which placement actually drove the clicks and the sales. A third compares two campaigns by giving each a distinct utm_campaign through a per-campaign override, so a subject-line or send-time test can be judged on revenue rather than opens. A fourth, advanced example builds an engagement funnel from GA4 server events using an Exploration over email_sent, email_click and your purchase event. The page closes with why data might not appear: GA4 takes 24 to 48 hours to finish processing, debug-mode traffic is excluded from standard reports, custom events never populate standard reports without an Exploration or key event, and unsubscribe and system links are deliberately never tagged.
