Topic: Issue with Assigning and Segmenting Custom Fields in Lists

Hello,

I'm not entirely sure if I understand how custom fields are supposed to add values to existing emails within a list. When I attempt to search for emails by segmenting based on custom fields I’ve recently assigned, I don’t seem to find the expected results.

For example, I have 1600 emails on a list. Yesterday, I sent an email to a random 500 of these emails and set a specific custom field for them. Today, I tried to segment the list to find those emails that don’t have this custom field by using "contains [EMPTY]" in the value field, but it didn’t work. Then I created a new custom field with the value set to [EMPTY] (and also tried "0"), but the segment still didn’t find anything.

When I manually check each email in the list, I can see that the value shows as [EMPTY] for those that don’t have the custom field, yet the segment search isn’t able to locate them.

Any insights on how to resolve this would be greatly appreciated!

If you add a custom field for a list then all subscribers will have that custom field. If you want to have a empty value for a custom field then you need to leave that custom field empty and don't insert [EMPTY] as value.
This is example how a empty custom field will look:

Then if you try to make a segment by this custom field and get all the subscribers then check this picture from bellow:

!!!!!! Make sure that after you create a custom field your sync-lists-custom-fields command is running. As you can see the info message after the custom field is added and form submitted.

When I create a new custom field, I only get the message "Your form has been successfully saved!"
