What Is An SMS Marketing API?

When one researches the features and services provided by SMS marketing providers, the SMS marketing API, and its efficiency 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 SMS API might use rest API Systems use java, python, json, PHP, as well as many other programming languages and can 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 the ability to copy files from one area to another without the developer having to understand the total file system operations.

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

How Does SMS API 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 email addresses or mobile phone numbers. A business must ensure that these audiences want to be conducted through the ability to opt-in, whether this is through sending shortcodes or sign-up forms, or OTP codes with a custom sender ID.

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

  1. The details are exported from an email program to the SMS campaigns on SMS marketing API platforms. 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. Two-factor authentication is often required.
  2. The marketing text message can be edited at any time and an SMS service provider or business can work out when the message needs to be sent, whether it is straight away or in a few days’ time.
  3. As an SMS text marketing client, one can monitor the marketing effectiveness by the take-up rate. Whether a 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 API Software Features

There is a lot that goes into sending a simple text message to a target consumer from a business’s chosen system. Luckily for American businesses, SMS marketing API software makes the process easy, and doesn’t require extensive information. Reliable, customizable, and scalable to your needs, an SMS API service is a way for developers to connect to a Bulk SMS gateway. This means the client can SMS-enable a website or a system process (such as an email to SMS database) to send and receive text messages in various ways.

The features of an SMS marketing API integration include:

  • Sending and receiving text messages through a reliable telecommunication carrier
  • Sending transactional SMS or SMS Confirmation or OTP messages.
  • Knowing which message has been sent to a given point of contact
  • Having the ability to receive incoming SMS from customers on android, iOS, and even WhatsApp.
  • Tracking messages with the time of day the message was distributed and received on the mobile phone
  • In the case of receiving information that a message has not been delivered, the ability to take appropriate action by continuing to deliver the SMS by a certain time
  • Knowing it is the real-time delivery of inbound SMS which is great for companies that need responses from customers or staff.

 

What Should You Look For In An Cheap SMS Marketing API?

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 its 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 can’t just automate, but must ensure they are following the rules to reduce the likelihood of running into trouble. For example, a company must gain permission from its audiences (in other words, enable them to opt-in), whether this is through a form, or texting a short code to a dedicated number. Some SMS API providers also have specific prices related to toll-free numbers, which needs to be checked across each provider.

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 shortcodes, which are five-digit numbers used for SMS messaging, and one should not be made to purchase but rather use the provider’s codes. Such services can be established for automatic replies to incoming SMS, therefore you should not be charged for inbound messages.

Overall, the reliability of the SMS marketing API provider is of the utmost importance. The reliability of an SMS company can be measured by its 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.
