Bulk SMS

Large quantities of SMS need the right provider and systems.

Bulk SMS is the sending of large quantities of SMS messages. This typically involves the use of an SMS gateway such as the Tyr SMS Gateway, located in the United Kingdom (UK), to send SMS to mobiles. Bulk SMS is usually associated with marketing campaigns and large broadcasts to customers, staff or other stakeholders.

Bulk SMS is the name given to the sending of a large number of SMS messages to a broad audience. It allows businesses to deliver SMS messages safely, quickly and directly to their customers worldwide. Use it for competitions, marketing campaigns, notifications to employees, promotions or events. Its ability to send a high volume of messages at the same time is what defines Bulk SMS.

How to send SMS

SMS can be sent programmatically from an application using SMS APIs and libraries or SDKs, by using an SMS text messaging add-on or extension to software (e.g. Microsoft Excel), by using an application with in-built SMS text messaging capability or by using a SaaS (software-as-a-service) application through your web browser. An example of a SaaS application for sending bulk SMS for marketing purposes is the Melrose Labs Campaign Solo service for SMS text marketing. Programming or scripting languages such as Python, PHP, Node.js, Go and others can be used with SMS APIs such as SMPP and REST to send and receive SMS.

How bulk SMS works

An SMS gateway allows an application to send and receive Short Message Service (SMS) messages to and from telecommunication networks. The vast majority of messages are routed by SMS gateways into mobile phone networks. An SMS gateway typically sits between the end user application that needs to send/receive SMS and a mobile network's Short Message Service Center (SMSC). Such gateways provide their customers with a choice of SMS APIs, including HTTP, SMTP, Short Message Peer-to-Peer (SMPP) and Web Services. Providers of SMS gateway services include SMS aggregators (such as the Melrose Labs Tyr SMS Gateway, located in the UK) and mobile operators. SMS gateways operate using software such as that provided by the Melrose Labs SMPP SMS Gateway.

When sending bulk SMS, an individual mobile can receive a single SMS or multiple SMS comprising a long message. When receiving a long message (aka concatenated SMS), the message is displayed to the mobile user once all parts comprising it have been received by the user's mobile. Bulk SMS can be used to deliver Rich Messaging via a link in an SMS, where the message contains an image, text, audio, video and CTAs. It can also be used to initiate a dialogue with the mobile user involving Conversational Chatbots.


The Melrose Labs SMSC Simulator can be used to simulate an SMSC and the delivery to mobiles of a bulk SMS campaign. Simulation can be used to test the performance of your sending application and its behaviour. Inbound messages from mobiles to your application can be generated to simulate responses from the mobile users receiving your campaign message.

Melrose Labs SMPP Implementation Testing can be used to simulate a messaging application and the submission of messages as part of a bulk SMS campaign. Simulation can be used to test the performance and SMPP compliance and capability of your SMSC, SMS gateway or SMPP server and its behaviour. Load testing can be performed where one or more simulated clients submit messages to your server-under-test and allows you to determine the SMS/sec and submit_sm/submit_sm_resp latency.
