Attributes
Attributes are the properties associated with an object. When used, they specify that you want to return only that property.
To reference an object's attributes, you simply append the object name with a dot “.” For example, if you want to insert a person's information into an email, you might specify:
Example
{{ subscriber.first_name }}
The preceeding example will return the first_name
attribute (in this case it is a custom field value) of the subscriber object if it is set, or nothing if it is not.
Subscriber Attributes
Subscriber attributes are typically any custom field associated with the subscriber object. Some common custom fields might include subscriber data like:
first_name
last_name
postal_address
city
zip_code
business_name
Essentially, whatever data you choose to collect and associate with your subscribers can be used in Liquid as attributes.
