Frequently Asked Questions

1. What is an SMS API?

An SMS API is a tool that lets your app or system send and receive text messages automatically. It helps businesses deliver OTPs, alerts, and promotions quickly and reliably, without manual work.

SMS marketing is sending marketing messages directly to customers’ phones via SMS or text message. Sometimes you might hear SMS marketing referred to as text message marketing. SMS marketing covers promotional messages such as product announcements, discount offers, abandoned cart reminders, and more.

Bulk SMS is when you send SMS to a large list of recipients. To send bulk SMS, you need:

  1. A reliable SMS service provider to handle large volumes.
  2. The right number type—e.g., A2P 10DLC (10-digit verified business numbers), short codes (5- or 6-digits), or toll-free numbers for high throughput.
  3. Meaningful, personalized messages so recipients engage rather than ignore or block you.
  4. Explicit opt-ins—only send messages to people who’ve expressly given permission.

A2P SMS (Application-to-Person SMS) refers to text messages sent from software or an application to a user’s mobile phone.

Common examples include OTPs, alerts, reminders, and promotional messages. It’s widely used by businesses for automated, high-volume communication.
