Operate an SMS gateway service using the Melrose Labs SMPP SMS Gateway platform. The globally distributed cloud-based SMPP SMS Gateway platform provides API and portal access for your customers to send and receive SMS, and gives you the ability to manage customers, billing, supplier connections and routing.
Use the SMPP SMS Gateway as your SMS switch to start a business in mobile messaging, provide your organisation with its own messaging capability, or upgrade your existing platform with greater reliability, capacity and capability. The platform comprises the SSG Administration Portal and messaging nodes located in the UK, Germany, Singapore, Australia, Brazil and the USA. The txtConsole end-user portal can be used by your customers as an alternative to APIs for sending and receiving SMS, and has a number of applications for marketing, customer onboarding, appointment reminding, staff communication, customer support and more.
For customers with a requirement of up to 100 million SMS/day, we currently recommend the Standard version of the SMPP SMS Gateway.
SSG Administration Portal
Administer your global SSG instance using the SSG Administration Portal. The portal provides many functions, and these are briefly described below. The SSG Management API can also be used to perform a number of these functions.
Connecting to a supplier's SMS gateway / SMSC, creating a customer SMPP account, and sending a message. From portal login to sending messages in under 3.5 minutes.
SMS gateway platforms, such as the Melrose Labs SMPP SMS Gateway, are an essential core element that enable the reliable delivery of SMS messages to and from mobile users. They are used by messaging aggregators to provide SMS services to their customers, enterprises to manage messaging between different parts of the business and upstream messaging providers, and DevOps teams in organisations to develop, test and deploy messaging capabilities.
The SMPP SMS Gateway handles the technical aspects of conveying messages from your customers, via your suppliers and onto mobile users, and allows you to monetise the service and charge your customers for the SMS traffic that they send and receive. Prepay and postpay charging models are supported.
Short Message Peer-to-Peer (SMPP ) is the API that is used to enable your customers to connect with SMPP SMS Gateway and for the gateway to connect with your suppliers. REST, SOAP, HTTP, SMTP and other SMS APIs can be made available to aid integration with customers and suppliers.
txtConsole End-User Customer Portal
The SMPP SMS Gateway includes the brandable/whitelabel txtConsole end-user portal for use by your customers as an alternative to APIs for sending and receiving SMS. It has a number of applications for marketing, customer onboarding, appointment reminding, staff communication, customer support and more. Your customers can also use it to look-up the status of individual messages and to see messaging reports.
