What is the difference between WhatsApp Business App and WhatsApp Business API?

The main difference between WhatsApp Business App and WhatsApp Business API lies in their use and functionality. The WhatsApp Business App is designed for small businesses and allows direct communication with customers, but it is limited to one-on-one interactions and does not support bulk messaging. On the other hand, the WhatsApp Business API is designed for medium and large businesses that need to manage high message volumes, automate responses, and send bulk messages officially. Unlike the app, the API enables advanced integration with CRM and marketing platforms like 360NRS, and is subject to stricter policies and approvals to ensure message quality and user privacy.

Is it legal to send bulk messages via WhatsApp?: Explanation of regulations and policies

Yes, it is legal to send bulk messages via WhatsApp as long as the platform’s policies and regulations are followed. WhatsApp requires businesses to obtain users' explicit consent before sending them marketing or transactional messages. This includes complying with privacy regulations, such as the GDPR in Europe, which requires personal data to be handled securely and with proper consent. Messages must be relevant and provide real value to the user to avoid being perceived as spam. Complying with these regulations ensures that the use of WhatsApp is beneficial for both the company and the user, while avoiding potential penalties or account blocks.

How much does it cost to send bulk messages on WhatsApp?: Factors that affect the cost

The cost of sending bulk messages on WhatsApp varies depending on several factors. First, the price depends on the rate WhatsApp applies per country, which can differ by region. Additionally, costs may increase depending on the message volume and level of personalization required. Other factors that can affect the cost include the type of message (transactional or promotional), the service provider used to manage the API, and any additional features such as automation or chatbot usage. Tools like 360NRS enable companies to manage these costs efficiently, optimizing campaigns to maximize ROI.

Can I send bulk messages without the user's consent?: Importance of permission and privacy

No, sending bulk messages without user consent goes against WhatsApp policies and privacy regulations. To protect user privacy, WhatsApp requires businesses to obtain explicit user consent before sending messages, especially if they are promotional in nature. Obtaining consent not only ensures legal compliance but also improves the customer relationship by demonstrating transparency and respect. Additionally, companies that fail to comply risk blocks and sanctions from WhatsApp, affecting their ability to communicate with users in the future.

What does it involve to send bulk WhatsApp messages?

¿A que nos referimos con WhatsApp masivo?
Mensajes en masa a través de WhatsApp Business API

Sending bulk WhatsApp refers to sending a high volume of messages simultaneously to multiple users through the WhatsApp Business API platform.

This API is the official WhatsApp solution for companies that want to manage mass communication campaigns in a formal and efficient way. Unlike the standard WhatsApp app, the API allows businesses to send messages at scale, segment audiences, and automate message flows while maintaining personalized and relevant content for each user.

The WhatsApp Business API is designed to integrate with marketing platforms like 360NRS, providing companies with the ability to handle messages securely, comply with privacy regulations, and respect each user's permissions.

In this way, bulk WhatsApp messaging becomes an ideal multichannel strategy for companies seeking to leverage the platform's power without compromising user experience or violating WhatsApp's usage policies.

Benefits of sending bulk WhatsApp in marketing
Impact on reach, engagement, and customer retention

The use of mass WhatsApp presents a number of strategic benefits in the multichannel marketing arena, particularly in terms of reach, engagement and customer retention

Extended reach

WhatsApp has over 2 billion users worldwide, allowing businesses to reach a vast audience regardless of location. Bulk messages sent through the API have an almost instant delivery rate, ensuring campaigns reach all recipients quickly and efficiently. This differs from other communication methods that may be subject to more reach limitations.

High engagement

Messages sent via WhatsApp have significantly higher open rates compared to other channels such as email marketing. Users are accustomed to continuous interaction on this platform, which increases the chances that a message will not only be opened but also read and, in many cases, responded to. This engagement allows companies to interact more closely and personally with their customers. This creates a positive and relevant experience for the user.

Customer retention and loyalty

By enabling more direct and personalized communication, bulk WhatsApp messages can help companies build long-term relationships with their customers. Campaigns specifically designed to retain users, such as exclusive promotions or personalized thank-you messages, are just some examples of their potential. This approach not only helps improve brand loyalty but also encourages positive word of mouth. Satisfied customers tend to recommend services to their contacts.

By using the WhatsApp Business API and platforms like 360NRS, companies can maximize these benefits. They structure marketing campaigns that not only reach customers but also create meaningful and lasting connections with them.

What is the purpose of sending bulk WhatsApp messages?

Special promotions and offers:
How to grab customer attention with effective campaigns

One of the most powerful uses of bulk WhatsApp messaging is promoting offers and special campaigns aimed at capturing customer attention immediately. Given the high open rate on this platform, businesses can use the channel to effectively communicate discounts, exclusive promotions, and flash sales.

The key to a successful promotional campaign on WhatsApp is timing: sending the message at the optimal moment to capture the customer's attention and guide them toward a purchase. Moreover, personalization plays a key role, enabling customers to receive tailored offers based on their preferences or purchase history. This increases the chances of conversion.

Reminders and notifications via WhatsApp

Reminders and notifications:
Examples of companies using bulk WhatsApp to manage appointments or events

Sending reminders and notifications via bulk WhatsApp is a widely used strategy in sectors like healthcare, education, and financial services. Companies in the medical field, for example, can send appointment reminders to patients to reduce cancellations or no-shows.

Educational and training platforms also use this type of messaging to remind students of their classes or exam dates.

This strategy not only improves punctuality and organization but also demonstrates commitment and customer care, strengthening the relationship with users and enhancing the company’s reputation.

Customer support at scale:
Ability to handle multiple customer inquiries at once

As the demand for quick and efficient customer service grows, bulk WhatsApp becomes a practical solution to handle multiple customer inquiries simultaneously.

Through the WhatsApp Business API, it's possible to integrate the messaging system with artificial intelligence tools and chatbots, allowing businesses to manage common questions automatically and in real time. This is especially useful in sectors with a high volume of daily interactions, such as e-commerce and banking.

With bulk WhatsApp, companies not only resolve inquiries promptly but also relieve the burden on their support teams, optimizing resources and time.

Loyalty and retargeting:
Strategies to attract and retain customers with personalized messages

Bulk WhatsApp is a valuable tool for implementing retargeting and customer loyalty strategies. Thanks to the ability to segment and personalize messages, businesses can send content tailored to each user's interests and previous behavior. For instance, a customer who abandoned their shopping cart may receive a personalized reminder, or a loyal customer might receive a thank-you message with an exclusive discount.

These practices not only increase retention rates but also foster trust and loyalty with the customer, boosting long-term brand value.
