What is the sender ID and when is it available?
The sender ID is unfortunately not available in the United States. Messages sent through BulkSMS.com in South Africa will carry one of our reply numbers, so that the recipient will be able to reply to the message and you will receive the reply in your inbox on the BulkSMS.com website and on the BulkSMS Text Messenger. It is also possible to forward replies to an email address. You can set the email address under ‘Email to SMS settings’ on the website.
