Hiya,
We have a complete workflow in HubSpot that sees a Landing Page host a survey (form), with prompts to fill in that survey going through SMS and email if not fille dout in a certain time.
However, we have an external mailhouse printing a unique QR code onto letters that starts this process. What we want is at the point that someone lands on the LP with the survey, to know that they came from their unique QR code and therefore attribute their survey answers to their HubSpot record. The HubSpot LP address will be in the code and we can ask for certain things to be put in the link.
We are dealing with 25k of records, so it needs to be a smooth process. We don’t want to gate the survey by asking people for their email address in order to identify them!
Help appreciated!
