When we are emailing to contacts from IFS we sometimes include links, that take them to some pages at our website. Some of these pages have opt-in forms, where we expect New users to enter their email.
But when a contact, that is already in IFS, gets there, we should not make the user submit the opt-in form again.
Is that technically possible?
- We could use links like http://example.com/page/?contactId=12345
- API script at our side would recognize ‘contactId’ parameter and:
- Hide IFS opt-in form if contact id is valid
- Fill in all cookies required by IFS for tracking purposes
That would work even if email link is clicked on a device, different from one, that was used for original opt-in
Is there any way of doing that?
