Introducing SleekFlow AI : Building The Ultimate GPT-4-Powered Customer Experience

In 2023, it is common for businesses to broadcast messages through SMS by integrating a text message API or SMS messaging API. However, a SMS messaging API can be quite costly for brands that are expanding fast, not to mention that the engagement rate is much lower as compared to WhatsApp. Moreover, if your business is looking to communicate with international customers out of the country, SMS broadcast is definitely not a viable solution. As businesses continue to explore new and more effective ways of reaching out to their customers, they start looking for SMS alternatives or solutions that are more effective than the SMS messaging API. 

While SMS has been the go-to communication channel for businesses for a long time, there's now a new player in the game: Messaging API for WhatsApp. As one of the most popular SMS alternatives, the Messaging API for WhatsApp offers a more versatile, secure, and cost-effective solution, which is quickly becoming the preferred mode of communication for businesses all over the world.

WhatsApp has an open rate of 98%, much higher than email with only around 20%.

What is a Messaging API?

A Messaging API, or a text message API, is a tool that enables businesses to send and receive messages from their customers on their own business platform. As an SMS alternative, Messaging API for WhatsApp makes it possible for businesses to integrate their WhatsApp Business account into their communication workflows without using a third-party interface from a WhatsApp BSP, allowing for automated messaging, chatbots, and other advanced WhatsApp Business features on their app while keeping 100% control over customer data.

How to use Messaging API as an SMS alternative

For businesses who are looking for an alternative to SMS 2fa or an alternative to SMS OTP, Here are some of the benefits of using a text messaging API over SMS:

One-time notifications

Messaging API is a great alternative to SMS OTP as it supports one-time notifications that are perfect for delivering timely and important messages to customers. One-time notifications can be used to send reminders, appointment confirmations, flight updates, and more. With a Messaging API for WhatsApp, businesses can also track the delivery status of these notifications, ensuring that customers receive them on time on their preferred instant messaging app.

2-factor authentication (2FA)

2FA is an additional security layer that requires users to verify their identity by entering a code that is sent to them through a messaging app. This process helps prevent unauthorized access to user accounts and information. In this case, WhatsApp can be used as an alternative to SMS 2FA as it offers end-to-end encryption for all conversations, making it secure for businesses and customers to communicate. A text messaging API for WhatsApp, as an SMS alternative, can provide a secure 2-factor authentication process, which is crucial for businesses that deal with sensitive data. 

WhatsApp Broadcast for promotional marketing

A text messaging API for WhatsApp supports WhatsApp broadcast, a feature that allows businesses to send promotional messages to a large number of customers at once. On the WhatsApp Business Platform, businesses can reach a wider audience and increase their chances of generating leads and conversions using personalized broadcast messages. Similar to other instant messaging options, this SMS alternative has an open rate of 98%, much higher as compared to emails. This feature also enables businesses to segment their customers based on demographics, preferences, and interests, ensuring that their messages are targeted with high accuracy.
