I have a campaign for which a contact can sign up via either SMS or email. If the contact wants to sign up via SMS, the email address is not required.
After signing up, the contact gets an email or SMS (based on the selection) with a link to a survey.
The issue I have is that for a contact who accessed the survey via the link in the SMS, the posted survey is not linked to his contact record in CRM.
Is there any way to make this link?
