What Is An SMS Gateway?

An SMS gateway allows a CRM, computer or e-mail to send and receive text messages through telecommunication network providers. Messages are routed through Short Message Services (SMS) mobile networks such as Telstra, Verizon and Vodafone. Most SMS Gateways support various SMS formats.

Applications of an SMS Gateway include:

  • Web SMS with contacts uploaded without software
  • E-mail SMS integrating SMS with e-mail programs
  • API SMS Services utilising CRM software

Within UK, text message gateways will either directly route to the major providers such as Optus, Telstra, Vodafone or aggregators. This will impact the speed and prices of text messages sent.

It should be noted that short message service (SMS) also known as a “text message” has a limit of 160 characters when send to another device. This means that messages exceeding this character limit will be split into multiple parts which may lead to higher sending charges.

What British Regulation Should I Consider?

When sending any text message campaign within UK, you must meet the Data Protection Act (2013).  Within UK the law states that no company can send legally unsolicited electronic messages. This applies to text messages through gateway with any message requiring:

  1. Consent – The receiver must have provided consent to receive text messages or be an existing customer who has an existing business relationship
  2. Identify – All text messages need to identify what business they came from
  3. Unsubscribe – There needs to be functionality to unsubscribe from future business SMS correspondence (2 way SMS). A company needs to ensure any such request is processed within five days.

From a compliance aspect, the SMS provider needs to feature a strong privacy policy, be SPAM compliant, have extensive terms and conditions and clear acceptable use policy. To learn more about direct marketing compliance you can view the UK direct marketing website created by the commonwealth.

Tips For Sending Business SMS Messages

Research has shown that short text messages perform the best. While 160 characters can exist within a text message, short and sharp messages that don’t require scrolling receive the optimal open rates and engagement. Try to only provide a single message, whether a greeting, reminder, offer or referral.

A mobile is personal so understand an individual’s personal space. Unexpected bulk SMS messages can be intrusive so ensure they are functional and courteous but not too familiar. Customisation tools can help maximise relevance but there is always a line an advertiser shouldn’t cross. Also, understand when the recipient will receive the text and reliability of the gateway. Nobody wants to receive a text at midnight!

Don’t over-use the bulk SMS marketing channel – Infrequent and brief messaged from businesses will ensure that users don’t unsubscribe from the communication. Use other channels such as e-mails to regularly update e-mails but avoid text messages for such communications.

Make sure you have a legitimate reason to send SMS messages – Ensure every message passes on useful information, acts as a reminder or clarifies an arrangement. As long as it has a legitimate use to an individual they will be happy to receive more text messages in the future.

Using A Premium SMS Provider

If your business send SMS messages to customers, clients, stakeholders or staff, then a premium direct gateway carrier is for you. Your message will be delivered directly to major text message service providers (such as Telstra & Optus). A text message gateway allows a computer to distribute or accept business SMS marketing transmissions to or from a telecommunications network. Most messages are usually routed into the mobile phone networks. ClickSend is one such example of an SMS gateway provider using a direct carrier.SMS API Text Message Gateway

What is an SMPP Gateway?

As a level-7 TCP/IP protocol is ensures speedy SMS message delivery. The SMPP can receive and send messages from mobiles including CDMA, UTMTS, GMA and UMTS phones.

How Can An British Business Integrate An SMS API?

Utilising an API is common practice by British businesses that have large-scale text message requirements. Developers connect to the SMS gateway through their preferred API from SMPP, Java, .NET, PHP or SOAP. Most providers will support SDKs through sample cost, documents and reusable libraries. Make sure the provider you choose has support levels that match your understanding of an SMS API as you may need a hands-on provider.

When setting up your API, the British SMS provider will provide you with sample code. This will allow you to connect to a SOAP API regardless of SMS API language you prefer. A provider like MessageMedia has samples o Java, GitHub in C3, Bash & Python as well as PHP. Other languages such as C++, Ruby and Powershell can also be utilised. Just talk to their support team when you first join and talk to their specialist SMS API technical support software person.

What Are The Benefits Of An SMS API Integration To A Text Message Platform?

API integration is so popular because:

  • Two-Way Messaging: The ability to send messages to the major British SMS networks and receive replies from the users.  
  • Message Tagging: A two-way SMS feature that reports on the exact application that an outbound message reply corresponds to.
  • Delivery Reporting: Track your text messages exact time they are received to handsets providing you a full delivery audit-trail.
  • Validity Period: Specify just how long a text message should be valid for so after this time, if the SMS has not been delivered it doesn’t get delivered.
  • API Web Push: Get real-time delivery of inbound text messages to a URL for quick replies of staff, customers unlike polling that can take time to validate
