 ### Available SnsMessage methods
 
-- `create([])`: Accepts an array of key-values where the keys corresponds to the methods below and the values are passed as parameters.
-- `body('')`: Accepts a string value for the notification body. Messages with more than 140 characters will be split into multiple messages by SNS without breaking any words.
-- `promotional(bool)`: Sets the SMS attribute as the promotional delivery type (default). Optimizes the delivery for lower costs.
-- `transactional(bool)`: Sets the SMS attribute as the transactional delivery type. Optimizes the delivery to achieve the highest reliability (it also costs more). 
-- `sender(string)`: Sets the SMS sender id. It can be up to 11 characters with no spaces.
