/**

 * @param static_segment *(optional but either `static_segment` or `options` is required)*

 * An array of emails to be used for a static segment.

 * Any emails provided that are not present on the list will be ignored.

 * Passing an empty array will create a static segment without any subscribers.

 * This field cannot be provided with the options field.

 *

 * @param options *(optional but either `static_segment` or `options` is required)*

 * The conditions of the segment. Static and fuzzy segments don't have conditions.
