To create a custom field, go to “Subscribers”. Click “Fields”. Here you can see all of the available default fields. To create your own, click “Add new field”. Give it a name and choose the type of field. “Text” - for any word your subscriber might need to put in. Like a name, city or an item. “Number” - for things like phone numbers. Date for birthdays or any kind of anniversaries. Click “Create”. Your new custom field is now live! This can be used in Autoresponders and when collecting new subscribers.
Quick note: There is a difference between default fields and the ones you create yourself. You can rename or delete the fields you create. However, you can’t delete the default fields.
