The request
“Add this tracking code to our email newsletter opt-in placements. Keep the current styling and button design exactly as they are. Nothing on the front end should change.”
Attribution was missing on signups. The forms themselves were fine.
The approach
We added the tracking to every opt-in placement across the site so signups are attributed correctly, leaving the visible forms untouched.
What we shipped
Tracking added to all opt-in placements
Form styling unchanged
Attribution verified on test signups
