I thought I found a workable solution yesterday (3/15) by including fields collected from the form (email, company name, etc) within the copy on the Thank You page, using the personalization tokens.
It worked well for contacts that already had been established within our database. The personalization torkens worked, and my Google team said that would work!
However, for brand new contacts that moved through the form, it appears HubSpot couldn’t process their data quick enough to include the personalization tokens within the Thank You page. Therefore, back to square one. I informed the Google team and my rep said several other clients were encountering the exact same issue.
I hope to receive some resolution from Google on this soon. When I do, I will provide an update on this thread.
