When you receive a text message, your phone always tells you something about where the SMS comes from. Either it says the name of a company or product you’re using, or a number from who has sent it, or even a combination if it’s a number that you have stored in your phone and it is replaced by your phone with the name under which you have that number saved! This is what we call the originator.
The amount of characters available to use as the originator depends on whether it’s a name or a number. If you’d like to enter your company name for example, this can be up to 11 characters. This is a limit that’s inherent to SMS as a format - so we can’t change this, unfortunately. There is no official minimum of characters that you should use but most phones can’t display 1 or 2-character originators; we recommend using between 3 and 11 characters.
It is NOT possible for the recipient to respond to this message directly. If your number is included in the message or if they’ve saved your contact information separately, they would be able to respond.
If you are sending out your messages with a phone number as originator, this can be up to 17 digits long. Keep in mind that you are sending messages from a global application: if you send a message to your US based recipients without the correct country prefix (738-134-5553) or to your UK recipients (0754849375) as originator, their phones will interpret these as internationally formatted Russian numbers (+7 prefix).
