What Is An SMS Marketing API?

When one researches the features and services provided by SMS marketing providers, the SMS marketing API, and the efficiency of this is always discussed. But what is an API? An API is an acronym for Application Programming Interface, which is an IT software allowing a programmer to formulate a computer program that will make it easier to send text messages to recipients in a quick and effective manner. An API may be for a web-based system, operating system or database system. Basically, it is a system that makes it easier for the programmer to gather and send information systematically. For example, the client may send an email with the text message required to be sent and the API file will give the developer an ability to copy files from one area to another without the developer have to understand the total file system operations.

Different SMS Marketing providers emphasise that an API is more than an exchange of text and image message service (SMS MMS) but a powerful software platform to simplify the text messaging service and ensure full and reliable delivery of bulk SMS messages.

How Does SMS Marketing Work?

To start the process, the client needs to upload a file that has all the names of people that wish to be contacted. This may include the email address or the mobile phone numbers. A business must ensure that these audiences want to be conducted through the ability to opt-in, whether this be through sending short codes or sign up forms.

After this, the SMS gateway API will go through the following process:

  1. The details are exported from an email program to the SMS marketing API platform. It can be established as an online calendar containing appointments or reminders. The data format is processed using platforms such as Google, Outlook.com, Yahoo, or iCloud. A two-factor authentication is often required.
  2. The marketing text message can be edited at any time and a business can work out when the message needs to be sent, whether it straight away or in a few days time.
  3. As an SMS marketing client, one can monitor the marketing effectiveness by the take up rate. Whether large or small business, such valuable information is extremely cost effective and the SMS API software has the ability to send delivery reports for analysis.
  4. The process can be completely automated or a business can opt to manually verify each text message before it is sent to add another form of personalization.

SMS Marketing Benefits

The leading SMS marketing API providers were analyzed and rated in accordance with their level of features in the graph below.

What Should You Look For In An SMS Marketing Service?

Firstly, a business must ensure that the SMS gateway provider follows the laws, regulations, and best practices around any SMS marketing activity. The SMS marketing provider must be anti-SPAM compliant and should have their own privacy policy in place for the security and confidentially of all parties involved. As the mobile marketing industry is highly personal, it is a heavily regulated communication channel, thus businesses must ensure they are following the rules to reduce the likelihood of running into trouble. For example, a company must gain permission from their audiences (in other words, enable them to opt-in), whether this be through a form, or texting a short code to a dedicated number.


From a marketing perspective, please do not use words like ‘free’ unless you have a free to end user condition. All promotions and communication should include name, description, conditions and the ability to opt-out if required.

Thirdly, SMS marketing providers should have short codes, which are five digit numbers used for SMS messaging, and one should not be made to purchase but rather use the providers codes. Such services can be established for automatic replies to incoming SMS, therefore you should not be charged for inbound messages.

It is best practice for a business to track specific keywords of a campaign to gather data and analytics for measuring success. Tools like the Google keyword planner can assist with this. Additionally, a business should be able to follow the mobile phone numbers being contacted to to determine whether they opt-in and opt-out of the marketing or promotional campaign.

Overall, reliability of the SMS marketing API provider is at the upmost importance. Reliability of an SMS company can be measured by their statement of an uptime guarantee, which should be at least 98%. This will mean that the provider’s success rate is almost at 100%. The core SMS providers have been outlined and rated below based on reliability.
