What are Bulk WhatsApp Messages?
In simple words, these are messages that are sent to a large number of people on WhatsApp at one go.
There is no restriction to the number of people who can receive notifications other than your number’s messaging tier with WhatsApp. Even people who have not saved your WhatsApp number can receive messages from you, if you're using WhatsApp API.
Bulk messages on WhatsApp help you save time and effort as you don't have to individually type out and send messages to each one of the intended recipients. These messages help you make the most of your resources and are a great way to distribute information instantly.
You can include images, videos and add as many characters as you want to make your messages more meaningful. WhatsApp bulk messages can be personalized to reach out to customers at scale using variables in your message template body.
By sending personalized messages to customers, your brand will be perceived as being reliable and trustworthy.
Use Cases of Automated Bulk Messages on WhatsApp
Businesses use WhatsApp’s bulk sending feature for a lot of purposes such as:
Keeping customers informed about upcoming events
Making announcements on new products launched
Promoting products by sharing offers and discounts
Reviving inactive or dormant users
Sharing order updates with customers and keeping them informed at all times
Real-world example:
A fresh foods company in South Africa sends a bulk WhatsApp message every morning to all its customers who will receive the fresh food in the next 3 hours. Earlier the same company would take an hour to manually send 100 messages. With bulk messages using WhatsApp API, that's reduced to 1 minute.

How to send bulk messages on WhatsApp without getting banned?
While the idea of sending out a particular message to a large group of people at once is appealing, you must be careful not to spam your customers.
There is a risk of getting your account suspended or banned if you take to the mass promotion of your products on WhatsApp's platform, which is a big no-no according to their terms of service. WhatsApp has laid out strict rules to protect the interest of its users. Any business that is seen indulging in mass spammy promotions can get ousted from the platform.
By all means, it does not mean that bulk messages are not allowed. As long as you play by the rules you can enjoy all the benefits of this feature with absolutely no risk. If you fail to do it the right way, you could end up getting your number blocked by WhatsApp — which translates to losing potential clients.
We have also noticed that regular WhatsApp Business app numbers get banned far more easily, whereas WhatsApp Business API numbers rarely get banned, if ever.
To evade this WhatsApp lets you send bulk messages through WhatsApp Business API. This is the advanced version of WhatsApp Business, launched to help fast-growing companies streamline their communication.
With access to WhatsApp Business API, you can send bulk automated messages to 1000s of customers who have given their consent via opt-in to receive messages from your business. DelightChat is one such WhatsApp bulk sender software you cna use to achieve this.
