    Long Message Concatenation

    Plivo’s Message API allows you to send SMS messages that exceed 160 characters. Plivo takes care of transmitting long messages with the appropriate metadata to ensure they are delivered as one intact message on the recipient’s handset.

    Delivery Report Notification

    Receive real-time delivery notifications for SMS messages that you send. You can also track delivery rates and review the performance of your account.

    Opt-out Handling

    Plivo automatically handles SMS opt-out if your Plivo number receives replies with an opt-out keyword. The following keywords are supported for opt-out:

    • Stop
    • Cancel
    • End
    • Quit
    • Unsubscribe

    SMS Data Redaction

    You can redact the sensitive information pertaining to Outbound as well as Inbound SMS messages. Enabling message redaction will make sure that the contents of the messages are redacted on Plivo servers, along with any debug logs.

    Outbound: To redact the content and destination number of an outbound SMS, set the ‘log’ request parameter of the Send SMS API request to ‘false’.

    Inbound: Enable this feature from your Plivo Console.

    Intelligent Message Encoding

    Plivo replaces Unicode characters with similar GSM characters to ensure message delivery to networks that do not support Unicode.
