I’m in the process of setting up a Preference Centre to allow users to manage their subscription preferences (via a link at the bottom of our automated emails). It makes sense for the user to click the link in their email and to have all relevant data pre-filled: their name, email address, and any current preferences they’re subscribed to.
I’m using a custom field to hold info on which list they’re subscribed to. However I’m having an issue with prefilling the custom field when the user has more than one checkbox selected.
Here are some example links:
- List 1 - prefilling only “list1” works as expected
- List 2 - prefilling only “list2” works as expected
- List 1 and List 2 - prefilling both “list1” and “list2” does not work, both are unselected
Is there a way to fix this? I’m not sure how I can format that personalization tag any different. If there’s a different way to achieve this I’m all for it, I just can’t figure it out.
