Thank you for your reply.
I was unable to add UTM tags.
I tried adding UTM tags using the steps below and then running aggregation in Looker Studio, but the aggregation was unsuccessful.
Are there any additional steps I need to take in addition to the steps below?
1. Add the Google Tag Manager code to the "Edit Page Meta Tags" section of the Marketo thank you page.
2. Insert UTM parameters into the link in the email.
3. Click the link in question.
4. Check whether aggregation was successful in Looker Studio.
I checked step 4, but aggregation was not successful.
If you know of any solutions, please let me know.
Thank you in advance.
