I'm a little confused about this one.
We are wanting to put quite a few custom fields on our newsletter subscription lists and to make segments based upon these values.
- general list for park viewers (easy, simply subscribed)
- add field to indicate they are interested in events with pets.
How would a user be able to change this value? Would it be a case of unsubscribing them, and resubscribing them?
We have a subscription/unsubscription form on our pages, but I can't work out how they would be able to see what they had already selected.
Please ask any questions if this doesn't make sense.
If you include a link to the preference center in your campaign, that will allow your subscribers to edit their preferences and fill in details in those custom fields.
