Add an Attribute

To retain more information about your subscriber, add an attribute. An attribute gives you more information to use when targeting or excluding subscribers from your sends.

You need to know this information to create an attribute:

• The name of the attribute
• The data type of the attribute
• Any applicable default value
• Whether the attribute accepts send time values
• Any required picklist options
• Minimum and maximum lengths
• Whether the attribute is required
• Whether the attribute is read-only
• Whether the attribute is hidden

You can’t create an attribute using the name of an existing attribute. After an attribute is added to a list, it’s available in all lists.
