Messaging Services is a free feature designed to make it easier to send messages at-scale, as well as across multiple countries.
In simple terms, a Messaging Service is a container for multiple message senders (e.g. phone numbers, Alphanumeric Codes). Messaging Services are required under A2P 10DLC to send message in the United States.
When sending messages internationally, the Country Geomatch feature automatically selects the Omnihub phone number in your Messaging Service to match the country of your recipient's phone number.
The Sticky Sender feature ensures the same From phone number is selected every time you send a message to a particular end-user. This allows you to consistently send messages to your user from a single, recognisable phone number.
