To implement SMS marketing campaigns, many businesses require the ability to send messages only one way - where the recipient can't reply to the sender.  Sinch’s one-way SMS includes multiple offerings that will cater to your specific needs, that is, local or global, sending transactional or promotional SMS.

Alphanumeric sender IDs

 

To send 1-way SMS messages, you need to use an alphanumeric sender ID.  This is an 11 character code that allows you to send one way messages as well as being a brand identifier.
