How to send bulk WhatsApp Messages Effectively?

Table of Contents

More and more brands and companies are turning towards WhatsApp as a marketing or customer engagement platform. Hence it becomes essential for them to send WhatsApp bulk messages to their customers.


Sending bulk WhatsApp messages to your target audience saves time and effort. In addition, it enables you to market your products and services effectively. Unfortunately, finding a reliable bulk WhatsApp message sender is difficult because most are unofficial tools.


Using such unofficial 'Bulk Message WhatsApp' tools may permanently ban your WhatsApp business number. 

What are Bulk messages?

Bulk messages are marketing messages sent to a large number of people (including potential clients) on WhatsApp at the same time.


Bulk messages on WhatsApp save you time and effort because you don’t have to type out and send messages to each recipient. Such messages help you make the most of your resources and are a perfect way to disseminate information quickly.


There is no cap on the number of people who can receive notifications. If you use the WhatsApp API, even people who have not saved your WhatsApp number can receive messages from you.


You can include images, videos, and as many characters as possible to make your messages more meaningful. Then, using variables in your message template body, you can personalise WhatsApp bulk messages to reach out to customers at scale.


If you send personalised messages to customers, your brand will be perceived as trustworthy and reliable.

Use cases of WhatsApp bulk messages

Companies use WhatsApp’s bulk messaging not just for user engagement but for a variety of purposes, including:


  • Making announcements about new products launched
  • Sharing offers and discounts to promote products
  • Keeping customers up to date on upcoming events
  • Reactivating dormant or inactive users

How do I send bulk WhatsApp messages?

  • Use WhatsApp’s Official APIs to send messages

An example of #2 is using WATI. WATI is an automated software built on top of the official WhatsApp Business APIs and designed to send WhatsApp messages in bulk directly from a PC/Laptop simply and effectively.

How do I send bulk WhatsApp messages without getting banned?

While it may seem appealing to send a specific message to a large group of people at once, you must be careful not to spam your customers.


If you use WhatsApp’s platform to promote your products in bulk, you risk having your account suspended or banned, which is against their terms of service. WhatsApp has established strict guidelines to safeguard its users’ interests. So they may ban any company that’s engaging in mass spammy promotions.


That is not to say that bulk messages are not permitted. You can enjoy this feature’s benefits with no risk if you follow the rules. However, if you don’t do it correctly, WhatsApp may block your phone number, losing potential customers.


We’ve also noticed that regular WhatsApp Business app numbers are far more easily banned. In contrast, WhatsApp Business API numbers are rarely, if ever, banned.


WhatsApp Business API allows you to send bulk messages to avoid this. In addition, the enhanced version of WhatsApp Business helps rapidly growing businesses streamline their communication.

What You Should Know Before Sending a Bulk WhatsApp Message

WhatsApp introduced phone number tiers, status, and quality ratings to protect its users from spam and promote high-quality bulk messages.

Phone Number Tiers

The tier of your phone number determines the total number of recipients you can send bulk messages via WhatsApp API. Therefore, the higher your phone number tier is, the more new contacts you message in 24 hours.

Phone Number Status and Quality Rating

Your phone number’s status and quality rating can affect your ability to send bulk messages on WhatsApp. A phone number’s status must be ‘Connected’ to send unlimited WhatsApp bulk messages.


If your phone number is reported or blocked, its rating falls low. As a result, its status will be changed to Flagged. You cannot upgrade your number’s messaging tier while it is Flagged. For example, suppose the quality rating does not improve within seven days. In that case, the status will revert to Connected, but with a lower messaging limit.


Your number will be assigned the Restricted status if it reaches its messaging limit while having a low-quality rating. A Restricted WhatsApp phone number can only answer incoming calls and send WhatsApp bulk messages to new unique Contacts.


To maintain a high-quality rating, only send high-quality WhatsApp bulk messages relevant to your Contacts.
