  • Intelligent Traffic Distribution
    Evenly distribute your outbound SMS and MMS traffic across phone numbers in your number pool. In-country numbers are given higher priority by default.
  • Source Number Queueing
    A dedicated rate-limiting queue per source number ensures that you never exceed the per-number message sending rates applicable in the US and Canada.
  • Priority Select
    Priority-based selection of short codes and automatic fallback to long code numbers based on destination.
  • Intelligent Message Encoding
    Automatically replace Unicode characters with similar GSM characters to ensure message delivery to destination networks that don’t support Unicode.
