In the response, "status" will either be "queued" or "unsubscribed". A "queued" status is a successful response and means that the message should be sent within seconds. An "unsubscribed" status means that the message will not be sent, as the customer has previously unsubscribed from messages from your business.
Please always include a country code (such as +1 for US) in all API calls to us.
We prevent multiple identical messages from being sent to a single customer within 7 seconds to preserve a great SMS experience.
If you send a message to a new phone number, the API will automatically create a new user.
