Identified during the [1] weekly call on 2026-03-11. Two related but distinct data integrity problems are causing GA4 to underreport email-driven traffic and conversion activity.
GA4 shows only 5 sessions attributed to the email channel despite an active ABM campaign with ~60% open rates and ~30% click rates across 101 accounts. A large portion of the ~886 "Direct" sessions are suspected to be email visits that were not properly tagged.
UTM parameters are missing or malformed on some links inside the ABM email sequences. When a recipient clicks a link without UTM tags, GA4 cannot identify the traffic source and falls back to "Direct."
"It's a policy in our organization that we use UTM links on every link, but I say that some of them don't get done sometimes." — Mark Hope
Audit all links in active HubSpot email sequences and ensure every link carries correct UTM parameters:
| Parameter | Expected Value (example) |
|---|---|
utm_source |
hubspot |
utm_medium |
email |
utm_campaign |
abm-sequence-1 |

The only event marked as a GA4 key event is the "Schedule a Demo" button click. No other user actions (form fills, downloads, video plays, etc.) appear as key events in GA4 reporting.
Additional conversion actions (e.g., lead form submit, newsletter signup) were configured in Google Tag Manager as Google Ads conversions only. They were not simultaneously marked as GA4 key events. This means:
"I think it's only tracking on the ads goals as conversions rather than on GA4 showing the organic key events." — Justin Dwyer
| Conversion Action | Google Ads | GA4 Key Event |
|---|---|---|
| Schedule a Demo click | ✅ | ✅ |
| Submit a lead form | ✅ | ❌ |
| Newsletter signup | ✅ | ❌ |
| Video plays | ❌ | ❌ |
| Document downloads | ❌ | ❌ |
| Phone calls | ❌ | ❌ |
Implement 5–6 new conversion actions in GTM and mark each as both a Google Ads conversion and a GA4 key event:

The two issues compound each other. Without sufficient conversion data in GA4 and Google Ads:
