Bulk SMS is the process of sending a large number of text messages to many people instantly. Instead of using a mobile phone to send messages one by one, businesses use a bulk SMS sender platform that delivers messages through powerful gateways. This ensures that customers receive important information quickly and without delay.
Sometimes this is also called Bulk SMS , which simply means the same message is sent to a group of users at the same time. For example, an e-commerce site can send delivery updates, a school can share exam schedules, or a bank can deliver OTPs for secure logins.
To make the process smarter, companies often use a bulk SMS API. This allows apps and websites to send messages automatically. For example, when you log into your account, the OTP you receive is sent through such an API. It can also be used for payment confirmations, appointment reminders, or promotional campaigns without manual effort. 
The biggest advantage of bulk SMS is that it is fast, affordable, and effective. SMS has one of the highest open rates compared to any other channel, which means almost every customer will read it. It works on any phone, even without internet, making it a reliable communication method for every business.
In short, bulk SMS is not just a messaging tool—it is an essential part of modern business communication. Whether for security, marketing, or simple updates, it helps organisations stay connected and build trust with their customers.
